How many batteries are in a pack?
You would take that number and divide it by 8.34. That would give you the price per battery. From there you can figure out how many batteries you can buy with only $3 and how much money would be left over.
Answer:
Add 7 to both sides
Step-by-step explanation:
You would need to add 7 to both sides to cancel out the 7 on the right side of the equation to get x one step closer to being by itself.
Then you would get 4x = -8.
Next divide by 4 on both sides to get x by itself so do the inverse operation of what 4 was doing to x.
x = -2
Answer:
p(4)=3
Step-by-step explanation:
p(4)=3(4)-9=12-9=3
The answer is $85.50
57 x 50% or 57 x .5 = 28.50
Add $28.50 to $57 and you get $85.50
