Answer:
You need to get a 95 on the next test to have a 90 grade average.
Step-by-step explanation:
(85 + 90 + n)/3 = 90
<u>Step 1: Multiply both sides by 3</u>
(85 + 90 + n)/3 * 3 = 90 * 3
85 + 90 + n = 270
<u>Step 2: Subtract 85 from both sides</u>
85 + 90 + n - 85 = 270 - 85
90 + n - 90 = 185 - 90
n = 95
Answer: You need to get a 95 on the next test to have a 90 grade average.
Answer:
0
Step-by-step explanation:
Since we're multiplying by 0, the entire product becomes 0.
step 2 would be 10
step 4 would be 10x-x = 9x =7
x = 7/9
None? Idk if that is the correct answer or not because I don’t feel like doing it
