Solve inequality -8x+4≤36.

BigorU [14]

$\bf{-8x+4\leq 36 }$

Subtract 4 from both sides.

$\bf{-8x\leq 36-4 }$

Subtract 4 from 36 to get 32.

$\bf{-8x\leq 32 }$

Divide both sides by −8. Since −8 is <0, the inequality direction is changed.

$\bf{x\geq \dfrac{32}{-8} }$

Divide 32 by −8 to get −4.

$\bf{x\geq -4 \ \ \Rightarrow \ \ \ Answer }$

What is the value of x?

Licemer1 [7]

Answer:

D. 16

Step-by-step explanation:

1. Because these are vertical angles (opposite pair of angles that are formed by intersecting lines), these are congruent. That means (8x-8) = (7x+8).

2. (Solving)

Step 1: Subtract 7x from both sides.

$8x-8-7x=7x+8-7x$
$x-8=8$

Step 2: Add 8 to both sides.

$x - 8 + 8 = 8 + 8$
$x = 16$

Step 3: Check if solution is correct.

$8(16)-8=7(16)+8$
$128-8 = 112+8$
$120 = 120$

Therefore, the answer is D. 16.
