Answer:
Question #4: Option A, 2 2/5
Question #5: Option C, x = 18
Step-by-step explanation:
Question #4
Step 1: Multiply both sides by 3
1/3b = 4/5
1/3b * 3 = 4/5 * 3
b = 12/5
b = 5/5 + 5/5 + 2/5
b = 2 2/5
Answer: Option A, 2 2/5
Question #5
Step 1: Multiply both sides by 3/2
2/3x = 12
2/3x * 3/2 = 12 * 3/2
x = 18
Answer: Option C, x = 18
