Answer:
7 hours
Step-by-step explanation:
We have that the value of the review of a bicycle has the following function:
v = 14 + 9 * t
where t is the time in hours
if we know that Aara paid a total of 77, that is v = 77, we can calculate the value of t, replacing:
77 = 14 + 9 * t
solving for t:
t = (77 - 14) / 9
t = 7
that is to say that Sara left the bicycle in a total of 7 hours

Answer:
with what
Step-by-step explanation:
I can't really see the question
M + s = 10 or s = 10 - m
<span>3m + 2s = 23 </span>
<span>substitute first equation into second equation: </span>
<span>3m + 2(10 - m) = 23 </span>
<span>3m + 20 - 2m = 23 </span>
<span>m = 3 </span>
<span>using first equation: </span>
<span>s = 10 - 3 = 7 </span>
<span>check using second equation: </span>
<span>3(3) + 2(7) = 23 </span>
<span>9 + 14 = 23 checks </span>
<span>He hit 7 stationary and 3 moving targets.</span>
Step-by-step explanation:
In this problem, we need to arrange 150 chairs in rows for a school play. You want each row to have the same number of chairs.
We can find the prime factorization of 150 as follows :
150 = 2, 3, 5, 5
150 is not a perfect square. 144 is a perfect square and 12² = 144. So, there are 12 possible arrangements.
