First, you need to distribute the right side of the equation : 8n - 2
Now the equation is : 20 - 7n = 8n - 2
Add 2 to both sides : 22 - 7n = 8n
Add 7n to both sides : 22 = 15n
Divide both sides by 15 : ( I had to round this one) 1.5 = n
To make both sides of the equations equal and balanced.
0.25=25/100=1/4. 1/4×84=84/4=21. The answer is 21
Answer:she need to do at least 3 hours of babysitting.
Step-by-step explanation:
you subtract how much she already has, 3$ from 25.50 and then you divide how much she makes in one hour of babysitting by how much money she needs so 22.50/7.50=3
5 tens because 6 tens plus 5 ones is equal to 65 and x tens plus 15 ones is equal to 65 also so it would be 5 tens because 5 times 10 equals 50 then plus 15 equals 65 so 65=65
Answer: 5 tens
Hope This Helps!!!
