Answer:

Step-by-step explanation:

Given the 2 equations

- 8x + 8y = 8

3x - 8y = - 18

Adding the 2 equations term by term gives

(- 8x + 3x) + (8y - 8y) = (8 - 18), that is

- 5x + 0 = - 10, that is

- 5x = - 10 → D

Answer:

-5x = -10

Step-by-step explanation:

Take the x terms, y terms and constants separately.

x: -8x + 3x = 3x - 8x = -5x

y: 8y + (-8y) = 8y - 8y = 0

Constant: 8 + (-18) = 8 - 18 = -10

Take all sums together

-5x + 0 = -10

-5x = -10

List 3 values that would make this inequality true 4n <_ 12

timama [110]

Divide both sides by 4 to get

$4n \le 12$

$\frac{4n}{4} \le \frac{12}{4}$

$n \le 3$

So we can pick n to be 3 or it can be less than 3

Three values we can pick are: n = 0, n = 1, n = 2

Or we could pick: n = 1, n = 2, n = 3
