Answer:
7(0.75) = 5.25
f = 7
Step-by-step explanation:
Ok I almost have the answer. Do you want me to explain how I did it?
Since he got 24 quizes in 6 weeks that means he gets 4 every week
24/6=4
so what is 32/4=?
32/4=8
the answer is 8
Answer:
2
Step-by-step explanation:
Find the greatest common factor of 8, 18, and 70.
Since we are looking for the Greatest Common Factor of the numbers given, we begin by factoring the numbers. It is usually easiest to start with the smallest number. Also, if there is a number that has obvious factors. In our case, satisfies both of these:
8=2⋅2⋅2 In fact,
8 only has one unique factor! If there is to be a common factor (other than
1 ) it must be
2. We now need to check that both
18 and 70 have 2 as a factor:
18=2⋅9
70=2⋅35 Therefore, 2 is the GCF of 8, 18 and 70.
