(1.) 4(x +2)=28
(2.) 2(x+4)=28
what dose x repsent
Simplifying
4(x + 2) = 28
Reorder the terms:
4(2 + x) = 28
(2 * 4 + x * 4) = 28
(8 + 4x) = 28
Solving
8 + 4x = 28
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8' to each side of the equation.
8 + -8 + 4x = 28 + -8
Combine like terms: 8 + -8 = 0
0 + 4x = 28 + -8
4x = 28 + -8
Combine like terms: 28 + -8 = 20
4x = 20
Divide each side by '4'.
x = 5
Simplifying
x = 5
2. 2 (x+4)=28
Simplifying
2(x + 4) = 28
Reorder the terms:
2(4 + x) = 28
(4 * 2 + x * 2) = 28
(8 + 2x) = 28
Solving
8 + 2x = 28
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8' to each side of the equation.
8 + -8 + 2x = 28 + -8
Combine like terms: 8 + -8 = 0
0 + 2x = 28 + -8
2x = 28 + -8
Combine like terms: 28 + -8 = 20
2x = 20
Divide each side by '2'.
x = 10
Simplifying
x = 10

Julie says that the most amount of time spent on homwork is 1 1/2 times the least amount of time spent on homwork who is correct explain
Required Data :
1 3/4, 2 1/2, 2, 2 3/4, 1, 1 3/4, 1 1/4, 3, 3 1/4, 3 3/4, 2, 2
Answer:
Julie is Incorrect
Step-by-step explanation:
Given the data:
1 3/4, 2 1/2, 2, 2 3/4, 1, 1 3/4, 1 1/4, 3, 3 1/4, 3 3/4, 2, 2
Arrangement in ascending order :

The least amount of time spent is : 1
The most amount of time spent is : 3 3/4
From Julie's assertion, that the most amount of time spent is equal to 1 1/2 the least amount of time spent.
Most amount of time = 1 1/2 * least amount of time
3 3/4 = 1 * 1 1/2
15/4 = 3/2
However, 15/4 ≠ 3/2
Hence, Julie is incorrect

3x 3x
9514 1404 393
Answer:
x = 5
Step-by-step explanation:
Perhaps you want to solve for x the rational equation ...
(2+5x)/(3x) = (7x -18 +2x)/(3x)
Multiplying by 3x and collecting terms, we have ...
2 +5x = 9x -18
20 = 4x . . . . . . add 18-5x to both sides
5 = x . . . . . . . . divide both sides by 4
The solution is x=5.

Assumed the base is a square
Find the height:

Basically there are two ways to find out the value of y. I'm gonna show you the both ways.
First one :
Find out the value of x first :[tex] \large{ \tt{x + 25 \degree + 35 \degree = 180 \degree}} \text{(Sum \: of \: angles \: of \: a \: triangle)}[/tex]
⇾ [tex] \large{ \tt{x + 60 \degree = 180 \degree}}[/tex]
⇾ [tex] \large{ \tt{x = 180 \degree - 60 \degree}}[/tex]
⇾ [tex] \large{ \tt{x = 120 \degree}}[/tex]
Now ,Find out the value of y[tex] \large{ \tt{x + y = 180 \degree}} \text{(Sum \: of \: angle \: in \: a \: straight \: line})[/tex]
⤑ [tex] \large{ \tt{120 \degree + y = 180 \degree}}[/tex]
⤑ [tex] \large{ \tt{y = 180 \degree - 120 \degree}}[/tex]
⤑ [tex] \boxed{ \large{ \tt{y = 60 \degree}}}[/tex]
Another way :
[tex] \large{ \tt{y = 35 \degree + 25 \degree}} [/tex] ( Exterior angle is equal to the sum of two non - adjacent interior angles )
↦ [tex] \boxed{ \large{ \tt{y = 60 \degree}}}[/tex]
➝ [tex] \large{ \boxed{ \boxed{ \tt{Our \: Final \: Answer : \underline{y = 60 \degree}}}}}[/tex]
