Idid all of them except for i need ive been trying for hour d:

#1 solve:
8+4/5 (15+2x)=-12
what should we do first?

finish solving it and what do you get for x?
a. -20
b. 5
c. -2

2.) solve. (short answer)

x + 4.5 = -6.7

3.) solve for x. 3/5 x=9

what should we do first?

finish solving it and what do you get for x?

a) 27/5
b) 30
c) 15

4.) solve for s. q=-6r+5s+3

5.) solve the inequality for x. (short answer)
-20 < -10 + 5g
make sure g is not the left for your final answer!

6.) solve the inequality for x. (short answer)
x+2.1≥8.4

7.) solve. (mc)
-25m < 125

8.) write an inequality that can be used to represent this situation, where x represents olivia’s sister’s age. (short answer)
olivia is 6 years older than her sister. the sum of their ages is no more than 28 years.

bonus: what is the oldest age her sister can be?

9.) solve for m. (multiple choice)
|m - 3| + 5 = 11
m = 19
m = -13 or 19
m = -3 or 9

solve for y. show all your work
3.2(5 – y) + 66.3 = 80 – 1.5(3y – 7)

solve the inequality and show all your work!
10x ≤ 4(3x + 2) - 14
