5(x-4) = 3x +4 What is the solution to this equation?
Answers
Answer:
x = 12
Step-by-step explanation:
1. Distribute:
5(x-4) = 5x - 20
2. Set equal to each other:
5x - 20 = 3x + 4
3. Simplify both sides:
5x - 20 = 3x + 4
-3x+20 = -3x+20
2x = 24
4. Solve:
2x/2 = 24/2
x = 12
5x+4=3x−4
Move all terms containing x to the left side of the equation.
2x+4=−4
Move all terms not containing x to the right side of the equation.
2x=−8
Divide each term by 2 and simplify.

how to use the gcf and distributive property to find each some: 32+48, 15+57, 98+14, 55+88
Answers
Answer:
For the first two:
16(2+3)
3(5+19)
Step-by-step explanation:
To find the gcf, you must list the factors of both numbers, and whichever one is greatest, you would put on the outside. Like 16 is the gcf of 32 and 48, so that number remains on the outside. Now, for the inside numbers, 16 times what equals 32? 16 times 2. 16 times what equals 48? 16 times 3 equals 48. Put those in the parenthesis, and put an addition sign in between them.
The use of greatest common factor and distributive property to find the sum is discussed above.
What is the distributive property of addition?The distributive property of addition state that -
a x (b + c) = (a x b) + (a x c)
Given are the following expressions -
32+48
15+57
98+14
55+88
We will first factor out the highest common factor and then apply the distributive property as follows.
[1]
32 + 48
8(4 + 6)
(8 x 4) + (8 x 6)
32 + 48
80
[2]
15 + 57
3(5 + 19)
(3 x 5) + (3 x 19)
15 + 57
72
[3]
98 + 14
14(7 + 1)
14 x 7 + 14 x 1
98 + 14
112
[4]
55 + 88
11(5 + 8)
11 x 5 + 11 x 8
55 + 88
143
Therefore, the use of greatest common factor and distributive property to find the sum is discussed above.

One week, Ellie earned $72.50 at her job when she worked for 5 hours. If she is paid the same hourly wage, how many hours would she have to work the next week to earn $232.00?
Answers
Answer:
16 hours
Step-by-step explanation:
Set up an equation the shows the amount she is paid for a certain amount of time. Assuming she is paid the same hourly wage:
[tex]\frac{72.50}{5}=\frac{232}{x}[/tex]
Solve for x. Cross multiply:
[tex]72.50x=1,160[/tex]
Isolate the variable. Divide both sides by 72.50:
[tex]\frac{72.50x}{72.50}=\frac{1160}{72.50}\\\\ x=16[/tex]
Ellie would need to work 16 hours to earn $232.00

1. SEASONING A health food store sells seasoning blends in bulk. One blend contains
20% basil. Sheila wants to add pure basil to some 20% blend to make 16 ounces of her
own 30% blend. Let b represent the amount of basil Sheila should add to the 20% blend.
Answers
Answer:
2
Step-by-step explanation:
From the question, One blend contains 20% basil.
Then here we have 20/100= 0.20
Sheila wants to add pure basil to some 20% blend to make 16 ounces of her
own 30% blend.
(30/100)B =(20/100)B +(amount Sheila want to add to make 16 ounces)
amount Sheila want to add to make 16 ounces= (30/100)B - (20/100)B
= 0.5B
amount Sheila want to add to make 16 ounce= (16-B)
0.5B= (16-B)
B=14
If substracted from the 16ounce we have 2.

Marco earned $360 helping his grandfather at his business,He spends 1/4 of his earnings on a gift for his mother and put 2/3 of the rest into a savings account.How much does he have left over for fun?
Answers
Answer:
$90

$360 is the total
1/4 was spent on the gift
so 360 times 1/4 is 90
360-90=270
we then do the same with this
270 times 2/3 equals 180
270-180=90
$90 left for fun

Step-by-step explanation:
If the perimeter of a rectangle is equal to perimeter of equilateral triangle. The one side of triangle is 4cm and breadth of rectangle is 3. Find the area of square.
Options
100 cm sq.
50 cm sq.
9 cm sq.
14 cm sq.
Answers
Answer:
Option : 9cm sq.
Step-by-step explanation:
Perimeter of equilateral ∆= perimeter of rectangle
side of ∆ = 4cm
perimeter of equilateral ∆ = 3 ( side) which is = 3 (4cm)
= 12cm
when, perimeter of rectangle = 12 cm
breadth = 3cm
length =?
since, perimeter = 2 ( l + b)
12 = 2 ( l + 3 )
12/2 = l + 3
6 = l + 3
therefore, length = 3cm
Area of square = (side)^2
Side = 3cm
Area = 9cm sq.
What is the absolute value of -20?
Use the number line to answer the question.
0-20
OO
O 20
O 40
Answers
Answer: |-20| = 20
Step-by-step explanation:
The absolute value of any number is always going to be that number in it's positive form. In this case, even if it was 20 the absolute value would still be 20. The absolute value is the number's distance from 0. So even if the integer is negative or not, it's distance will still be the same. Hope this helps !
The absolute value of -20 is 20.
To find the absolute value of -20, use the number line representation. The number line helps us visualize the position and magnitude of numbers.
At zero and move to the left. We first locate -20 on the number line. Starting from zero, 20 units to the left, which lands us on the point representing -20.
To find the absolute value, disregard the sign and consider only the magnitude measure the distance from zero to -20 without considering the direction the distance from zero to -20 is 20 units.

Find the equation of a line parallel to y=6x-4 and through point (-2,14)
Answers
Step-by-step explanation:
Substitute the slope from original line (3 in this case) into the equation of the line
$ y = \red 3 x + b $
Step 2
Substitute the given point (1, 7) into the x and y values
$ y = \red 3 x + b \\ 7 = \red 3 (1) + b $
Step 3
Solve for b (the y-intercept )
$ \begin{align*} 7 &= 3 (1) + b \\ 7 &= 3 + b \\ -3 & -3 \\ \hline \\ 4 &= b \\ \end{align*} $
Step 4
Substitute this value for 'b' in the slope intercept form equation $ y = 3x + 4 $
