Answer:
180 CDs
Step-by-step explanation:
So if Sam has 84 CDs, and the ratio from Sam to Alice is 7:8, we can do 84/7=12 so each number is equal to 12. Then we add up 7 and 8 and get 15, so we do 15*12 and we get 180.
Step-by-step explanation:
3.38 ×
is the scientific notation of 3,380,000
Subtract 8 from both sides and then multiply both sides by -5
V = -5
