Answer: X would equal -7

Step-by-step explanation: First off, we cross multiply. So 374/(x-10) = -22/1 would be: 374 = -22(x-10). We then get 374 = -22x +220. You would subtract 220 from both sides then divide by -22 to get x. You could then substitute -7 in for x, to check your answer.

X= 48 is the correct answer. You can always plug in 48 back into the original equation and make sure it works.
48-23+84+48+23=180

-4(3+n)>-32 Please Solve just like the picture

$n$

The number line is shown in figure attached below.

Step-by-step explanation:

We need to solve the inequality $-4(3+n)>-32$ and find value of n.

Solving the inequality:

$-4(3+n)>-32$

Multiplying -4 with terms inside the bracket.

$-12-4n>-32$

Adding 12 on both sides:

$-12-4n+12>-32+12$

$-4n>-20$

Divide both sides by -4 and reverse the inequality:

$n$

The number line is shown in figure attached below.

The number line starts with 5 with unfilled hole because n is less than 5 and moves towards left of the number line, because all values less than 5 are included in number line.
