Answer:
60 hours
Step-by-step explanation:
We want Joanna's total savings to be ...
bank account + gift + earnings = 1000
300 +100 +10h = 1000
10h = 600 . . . . subtract 400
h = 60 . . . . . . . .divide by 10
Joanna needs to babysit for 60 hours to earn the money she needs.
The answer is D f(x)=2(4^x)+3
Step 1-Distributive Property
8c-72=12c-2-4c
Step 2-Combine Like Terms
8c-72=8c-2
Step 3-Divide both 8c's by 8
-72=-2 -72 does NOT equal -2 so this equation has no solution...Hope this helps have a great Day!!!
