Answer: 7 multiple choice questions and 8 free response questions
Step-by-step explanation: m is the number of multiple choice questions and f is the number of free response questions.
m+f=15
m+2f=23
You can subtract the first equation from the second, and get f=8
m+8=15
m=7
Answer:
the mean is 8
Step-by-step explanation:
added them all together and divided by 7
A. Expanding the given expression, you have
balance = 75r^2 +150r +75
B. For r=0.10, the balance after 2 years is 75*1.1^2 = 90.75
C. The difference between $120 and 90.75 is $29.25. You need $29.25 more to buy the bicycle.
