Translate the phrase into a variable expression: twice the sum of a number and 5
Answer:
'Twice the sum of a number and 5' can be translated into variable expression such as:
2(n + 5)Step-by-step explanation:
Given the phrase
Twice the sum of a number and 5
First, let us breakdown the English Phrase
Let the number be = n
The sum of a number 'n' and 5 = n + 5
now, twice the sum of a number and 5 can be determined by multiplying (n+5) with 5.
Thus,
'Twice the sum of a number and 5' can be translated into variable expression such as:
2(n + 5)What is the greatest common factor (GCF) of 72 and 96?
Answer: GCF is 24 ^-^
Answer:
The first step to find the gcf of 72 and 96 is to list the factors of each number. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36 and 72. The factors of 96 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48 and 96. So, the Greatest Common Factor for these numbers is 24 because it divides all them without a remainder.

Claudia invests $4000 in an account that compounds continuously at a rate of 3.5%. How much money will he have in her account after 10
years?
Answer:
$5,400
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3.5%/100 = 0.035 per year,
then, solving our equation
I = 4000 × 0.035 × 10 = 1400
I = $ 1,400.00
The simple interest accumulated
on a principal of $ 4,000.00
at a rate of 3.5% per year
for 10 years is $ 1,400.00.
need assistance with the following
149.50 + 15x
I am solving for x
Answer:
You can't
Step-by-step explanation:
This is just an expression that has been simplified. You would be able to solve for x if this was an equation.
149.5 +15x=149.5 +15x get variables to one side
-15x
149.5=149.5
there the same
So there are no for x that can make this equation true

During the spring sale at a store, a sweater was marked down from $50 to $20. By what percent was the sweater decreased?
Group of answer choices
A. 60%
B. 50%
C. 30%
D. 150%
Step-by-step explanation:
Decrease in price = $50 - $20 = $30.
Percent of decrease = ($30/$50) * 100% = 60%. (A)
Based on the original price and the price the sweater decreased to, the percentage discount was 60%.
What was the Percentage Discount?The percentage reduction can be found as:
= (Original price - Discount price) / Original price x 100%
Solving gives:
= (50 - 20) / 50 x 100%
= 60%
In conclusion, the correct answer is option A.

a car traveling 100 miles in 2 hours has a unit rate of _miles per hour ?
Answer:
Unit rate of 50 miles per hour.
Step-by-step explanation:
We know that the car can travel 100 miles in 2 hours.
We can divide the 100 miles by how many hours there are to make it "per hour".
Showing you so it makes more sense...
100/2 = 100 ÷ 2
= 50
Double checking because why not...
50 x 2 (hours) = 100

15,500 for 7.5 years at 4.2% annual compound interest. Find the interest earned:
Answer:
$4882.50
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4.2%/100 = 0.042 per year,
then, solving our equation
I = 15500 × 0.042 × 7.5 = 4882.5
I = $ 4,882.50
The simple interest accumulated
on a principal of $ 15,500.00
at a rate of 4.2% per year
for 7.5 years is $ 4,882.50.
Answer:
$5602.78
Step-by-step explanation:
For for compound interest is A = P(1 + r/n)^(nt) where A is the new total, P is the amound invested, t is the number of years, r is the rate of interest and n is the number of times each year the interest is figured. In your problem, P = 15500, r = .042, n = 1. t = 7.5. So, substituting in we get
A = 15500(1+.042/1)^7.5(1)
A = 15500(1.36146...) = 21102.78
Therefore the interest earned is 21102.78-15500 = 5602.78

Step-by-step explanation:
If there are 2 boys and 5 altogether, means there are 3 girls. The ratio of boys to girls would be 2:3.
Look at all the first and second options as fractions to make things simpler. Simplify the fractions and see which ones are equivalent to 2/3
4/10 = 2/5 FALSE
8/12 = 2/3 TRUE
Options 3, 4, and 5 are comparing boys to all students, so whatever matches the ratio 2/5 is true.
10/25 = 2/5 TRUE
20/30 = 2/3 FALSE

How do you know what the solution is to a system of equations by graphing?
Answer:
I'm not 100% sure but I think if you graph them all
where they intersect is the solution
Answer:
The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.

We solve the above question using Lowest Common Multiple Method.
Find and list multiples of each number until the first common multiple is found. This is the lowest common multiple.
Multiples of 6:
6, 12, 18, 24, 30, 36, 42
Multiples of 15:

Therefore,
LCM(6, 15) = 30
Therefore, the NEXT time he will be cleaning his room and washing his windows on the same day is in 30 days time
The area of a rectangle is 8w +18 square feet. The length of the rectangle is 2 feet. Use factoring to
write an expression to represent the width of the rectangle.
Pls help ASAP
Answer:
The expression that represents the width of the rectangle is 4w + 9
Step-by-step explanation:
The formula of the area of the rectangle is A = length × width
Let us solve the question
∵ The area of a rectangle is 8w + 18 square feet.
∴ A = 8w + 18
∵ The HCF of 8 and 18 is 2
→ Divide each term of the area by 2 to get 2 as a common factor
∵ 8 ÷ 2 = 4 and 18 ÷ 2 = 9
∴ A = 2(4w + 9)
∵ The length of the rectangle is 2 feet
→ Substitute it in the formula of the area above
∵ A = 2 × width
∴ A = 2 width
→ Equate the two right sides of the area
∴ 2 width = 2(4w + 9)
→ Divide both sides by 2
∴ The width = 4w + 9
∴ The expression that represents the width of the rectangle is 4w + 9

Give the other guy a brainliest they deserve it :)
Step-by-step explanation:
Molly's hair was 20 inches long. Three years later it was 53 inches long. What was the percent increase, to the nearest hundredth, of Molly's hair length.
Find how much it grew:
53 - 20 = 33 inches.
Divide the amount it grew by the original length
33/20 = 1.65
Subtract 1:
1.65 - 1 = 0.65
Multiply by 100 for percent:
0.65 x 100 = 65%
The percent increase is 65%

Acompact disc box is 11.5 cm long,7 cm wide and 1.5 cm tall. What is the total surface area of a stack of five such compact disc boxes?
Answer:
1,172.5cm²
Step-by-step explanation:
Total surface area of a box = 2(LW + WH + LH)
L is the length = 11.5cm
W is the width = 7cm
H is the height = 1.5cm
Substitute
TSA = 2(11.5(7) + 7(1.5) + (11.5)(1.5))
TSA = 2(80.5+10.5+17.25)
TSA = 2(117.25)
TSA = 234.5cm²
Hence the total surface area of a stack of five such compact disc boxes will be 5(234.5) = 1,172.5cm²
Factor out the greatest common factor.
14x2 - 4x
Answer:
The greatest common factor of 14x² - 4x is: 2x
Step-by-step explanation:
Given the expression
14x² - 4x
The first step is to factor out the greatest common factor from each term
14x² = 2 · 7 · 14 · x · x
4x = 2 · 4 · x
so
G.C.F = 2 · x
G.C.F = 2x
Therefore, the greatest common factor of 14x² - 4x is: 2x
Is your estimate larger or smaller than the actual number of liters in a gallon? Explain how you know.
Question:
There are 33.8 fluid ounces in a litre. There are 128 fluid ounces in a gallon. About how many litres are in a gallon?
Is your estimate larger or smaller than the actual number of litres in a gallon? Explain how you know
Answer:
It is larger
Step-by-step explanation:
Given
[tex]33.8\ fl\ oz = 1\ litre[/tex]
[tex]128\ fl\ oz = 1\ gallon[/tex]
Required
Estimate number of litres in a gallon
[tex]33.8\ fl\ oz = 1\ litre[/tex]
[tex]128\ fl\ oz = 1\ gallon[/tex]
Cross Multiply
[tex]128\ fl\ oz * 1\ litre = 33.8\ fl\ oz * 1\ gallon[/tex]
[tex]128 * 1\ litre = 33.8* 1\ gallon[/tex]
Divide both sides by 33.8
[tex]\frac{128 * 1\ litre}{33.8} = \frac{33.8* 1\ gallon}{33.8}[/tex]
[tex]\frac{128 * 1\ litre}{33.8} = 1\ gallon[/tex]
[tex]3.78698224852\ litre = 1\ gallon[/tex]
Approximate
[tex]3.787\ litres = 1\ gallon[/tex]
The estimate is larger than the actual litres to gallon conversion because, in standard units of conversion;
[tex]3.785\ litres = 1\ gallon[/tex]

Oceanside Bike Rental Shop charges a 15 dollar fixed fee plus 9 dollars an hour for renting a bike. Melanie paid 60 dollars to rent a bike. How many hours did she pay to have the bike checked out ?
Answer:
5 hours
Step-by-step explanation:
First, you have to subtract the fixed fee of $15 to the total amount that Melanie paid. This has to be subtracted since one has to pay for this every time he/she rents a bike.
$60 - $15 = $45Next, you have to divide $45 by $9/hour in order to know how many hours Melanie rented the bike.
$45 ÷ $9/hour = 5 hoursTherefore, Melanie had the bike checked out for 5 hours.
Answer:
Step-by-step explanation:
$60 cost minus fixed fee of $15 equals $45
$45 divided by $9 equals 5...she had it for 5 hours.
