Can you help me solve 13 please 100 points

Answer 1

Answer:

Option A, 70

Step-by-step explanation:

Step 1:  Find the Science grade

(95 + 85 + 90 + 80 + x) / 5 = 84

Step 2:  Multiply both sides by 5

(95 + 85 + 90 + 80 + x) / 5 * 5 = 84 * 5

95 + 85 + 90 + 80 + x = 420

Step 3:  Combine all of the numbers

95 + 85 + 90 + 80 + x = 420

350 + x = 420

Step 4:  Subtract 350 from both sides

350 + x - 350 = 420 - 350

x = 70
