4.5(4-x) + 36 = 202 - 2.5(3x + 28)

Distributive property

18 - 4.5x + 36 = 202 - 7.5x - 70

Combine like terms

-4.5x + 54 = -7.5x + 132

Add 7.5x to both sides

3x = 78

Divide both sides by 3

x = 26

Is 15b+4=25.6 equivalent to 0.6+15b+4=25.6

pychu [463]

No because
15b + 4 = 25.6
15b = 21.6
b = 1.44

0.6+15b+4 = 25.6
4.6 + 15b = 25.6
15b = 21
b = 1.4

The answers are not the same therefore they are not equivalent.

Galina-37 [17]

Answer: 283

Step-by-step explanation:

To do this, it is helpful to get an equation you can use to solve any term.

This equation is:

$13 + 9(n-1)$

So simply plug in 31 for n to get

$13+9(31-1)$

$=13+270$

$=283$
