Greetings from Brasil...
According to the statement of the question, let X be any number. If this number X has to be less than 15, we can write:
X < 15The number is less than 15 and it can be represented by x < 15.
It is given in the question that a number is less than 15.
We have to represent it by translating inequalities.
How will we represent 10 times of x ?
The answer will be 10x.
Let's assume the number is X.
⇒ X < 15 (as per the question)
< symbolic is for less than i.e., X is less than 15.
X represents an unknown value, i.e., numbers less than 15 are 14, 13, 12,...etc.
Thus , if a number is less than 15 , it can be represented by x < 15.

9n - 6 = 5n + 18
Solve
Answer:
n = 6
Step-by-step explanation:
9n - 6 = 5n + 18
Subtract 5n from each side
9n-5n - 6 = 5n-5n + 18
4n -6 = 18
Add 6 to each side
4n -6+6 = 18+6
4n = 24
Divide each side by 4
4n/4 = 24/4
n = 6

Which rays are part of line BE?
Ac and
O AB and AĖ
AC and AB
AB and F
Answer:
We are given a diagram with different rays and lines.
Note: A line can be extend more and more upto infinitely length from both of the ends but a ray can be extend from end only.
We need to find the rays for the line BE.
We can see BE line has a point A in between line.
So, we can name the rays formed with end point A as AB and AE.
Therefore, AB and AE rays are part of line BE.
So, the correct option is 2nd option :
AB and AE.

Mkay, let's do this.
If x = 5 we can replace all the x-values with 5. Like so,
[tex]5^{2} + 2[/tex] alright, now [tex]5^{2} = 25[/tex] then add two.
For the bottom it's just 5+4=9 we've now got a new fraction.

Calculate the length of segment RS¯ with midpoint, M, if RM=5x and MS=x+12.
Answer:
So M is the midpoint of RS lmbo
Step-by-step explanation:
What you have here are lengths of two equal segments, expressed as different algebraic expressions.
you just set those two expressions equal, and solve for x. Then plug that x into EITHER of the two expressions, to get the equal lengths of RM & MS.
the volume of the truck is 162 yards. To find how many cubes will fit in each dimension, divide that length by the side of the cube
Answer:
180 cubes would be fit inside the truck
Step-by-step explanation:
well we know 1 cube is 1/10 of a yard
so let’s make it a easier number and say 10 cubes is 1 yard (you multiply 10 on each side, as long as you multiply the same number, which can be any number but I use 10 since it’s easier, on both sides, it’ll be the same thing.
so 162/10=16
So 16, 10 cubes si we multiply those two and you’ll get 160.
But there’s 2 yards not filled yet, we know that 1 yard is 10 cubes, so 2 yards would be 20 cubes.
so 160+20=180
180 cubes

A garbage company recycles ½ tons of plastic every 3 minutes. At this rate, approximately how many tons of plastic does the company recycle in two days?
Answer:
Total number of minutes in 2 days = 2880
Total time used for recycling garbage in 2 days = 2880/3 = 960
If 3 minutes = 1/2 tons
Then 960 minutes = 960*1/2 = 960/2 = 480
Therefore 480 tons of garbage where recycled in 2 days

what is equivalent to (10+7r-r^2)+(-6r^2-18+5r)
Answer:
- 7r² + 12r - 8
Step-by-step explanation:
Given
(10 + 7r - r² ) + (- 6r² - 18 + 5r) ← remove parenthesis
= 10 + 7r - r² - 6r² - 18 + 5r ← collect like terms
= - 7r² + 12r - 8
The expression (10 + 7r - r² ) + (- 6r² - 18 + 5r) is equivalent to - 7r² + 12r - 8 after applying the property.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that:
The expression is:
(10 + 7r - r² ) + (- 6r² - 18 + 5r)
Using distribution property:
After applying the above property the expression can be written as:
10 + 7r - r² - 6r² - 18 + 5r
Adding like terms:
- 7r² + 12r - 8
Thus, the expression (10 + 7r - r² ) + (- 6r² - 18 + 5r) is equivalent to - 7r² + 12r - 8 after applying the property.

As an aid to the establishment of personnel requirements, the director of a hospital wishes to estimate the mean number of people who are admitted to the emergency room during a 24-hour period. The director randomly selects 64 different 24-hour periods and determines the number of admissions for each. For this sample, X = 396 and S = 100. Using the sample standard deviation as an estimate for the population standard deviation, what size sample should the director choose if she wishes to estimate the mean number of admissions per 24-hour period to within 1 admission with 99% reliability, what size sample should she choose?
Answer:
Sample size n = 16
Step-by-step explanation:
We use the formula for Margin of Error for the question
Margin of Error = z × Standard deviation/√n
Margin of Error = 1
z score for 99% confidence interval = 2.576
Standard deviation = 100
1 = 2.576 × 100/√n
1 × √n = 257.6
√n = 257.6/1
n = √257.6
n = 16.049922118
Approximately = 16
Therefore, the sample size = 16

Which polynomial is in standard form?
Answer:
C
Step-by-step explanation:
Standard form is [ ax² + bx + c ]
The exponents and variables determine what comes first. In [ 11x³ - 6x² + 5x ], we can see that the exponents are going from greatest to least and the last number doesn't have an exponent so it goes last. Essentially we can think of this as sorting each part from greatest to least using exponents -> variables -> number to determine that.
Best of Luck!
how can you tell whether a square root of a whole number is rational or irrational
Answer:
Real numbers have two categories: rational and irrational. If a square root is not a perfect square, then it is considered an irrational number. These numbers cannot be written as a fraction because the decimal does not end (non-terminating) and does not repeat a pattern (non-repeating).Step-by-step explanation:
Solvefor x. x+3/5 =2
Answer: x=7/5 or 1 2/5
Step-by-step explanation:
Given
x+3/5=2
Subtract 3/5 on both sides
x+3/5-3/5=2-3/5
x=10/5-3/5 (This is to convert 2, as a integer, to a fraction in order to ease the
x=7/5 operation)
