7 0

Greetings!

$12-3(x+1)=30$
Distribute the Parenthesis.
$12-3x-3=30$
Combine like terms.
$9-3x=30$
Add -9 to both sides.
$(15-3x)+(-9)=(30)+(-9)$
$-3x=21$
Divide both sides by -3.
$(-3x)/-3=(21)/-3$
The Answer Is:
$x=-7$

Hope this helps.

Write an inequality from (–5) to (–1) inclusive

skad [1K]

Answer:

$-5\leq x\leq -1$

Step-by-step explanation:

This is a compound inequality that basically states that the X value is greater than or equal to -5, but less than or equal to -1. It is inclusive, because it includes both numbers and therefore should have an equal to sign ( $\leq or \geq$ ) instead of just less than or greater than ( < or >).
