Answer:

Does this problem have a picture, I just need to make sure I am seeing everything correctly thanks!

Step-by-step explanation:

a. -4 and 4b + 4 = 4b

-4 and 4b + 4 = -4 + (4b + 4) = 4b + (4 - 4) = 4b + 0 = 4b

b. 3x and 1 - 3x = 1

3x and 1 - 3x = 3x + (1 - 3x) = 1 + (3x - 3x) = 1 + 0 = 1

Put the values of the variables in place of the variables in the expression, then do the arithmetic.

$8p+3q-18\\\\=8\left(\dfrac{1}{2}\right)+3(7)-18=\dfrac{8}{2}+21-18\\\\=4+21-18\\\\=25-18\\\\=\bf{7}$

Use inverse operations and properties of equality to isolate the variable m+31=307

otez555 [7]

ANSWER

$m = 276$

EXPLANATION

The given equation is

$m + 31 = 307$

We add the additive inverse of 31 which is -31 to both sides of the equation to get,

$m + 31 + - 31= 307 + - 31$

Simplify;

$m +0= 307 - 31$

$m = 276$
