Answer:
B
Step-by-step explanation:
Solve the inequality using inverse operations to isolate x.
13x > -5 Divide by 13 on both sides
13x/13 > -5/13
x > -5/13
D. 10 x 62
If one row needs 62 bricks and there's 10 rows, you multiply them to get how many bricks nick needs
Part A: Charlie's answer is incorrect
In step 2 of Charlie's answer he subtracted 5 from each side. Since 5x is multiplication, he must DIVIDE each side by 5 to get x by itself. The problem should have worked out like this...
Step 1: 5x = 30
Step 2: x = 30/5
Step 3: x = 6
Part B: There is only 1 solution for this problem.
