Answer:
i believe the answer is -2n=5
Step-by-step explanation:you subtract the 3n with the n and -2n cant go into 5
First one
20=n/5+10
minus 10 both sides
10=n/5
times 5 both sides
50=n
2.
hmm
expand
p(x)=2x^2+5x+3-3x-3n
p(x)=2x^2+2x+3-3n
it looks like the coefients of the x terms are divisble by 2
because
if we have
p(x)=2(something)
the p(x) is divisible by 2
therefor that factor is 2 or -2
find what value of n works
so
3-3n=a multipule of 2
we are given
-3,-2,0,2
try each
3-3(-3)=3+9=12, that's divisble by 2
3-3(-2)=3+6=9, that's not divisible by 2
3-3(0)=3, that's not divisble by 2
3-3(2)=3-6=3, that's not divisble by 2
the onnly one that woks is when n=-3
answer is A

Explanation is in the comments by the way.
Answer:
0.95 miles per minute
19 miles in 20 minutes
Step-by-step explanation:
To find out how many miles traveled in a minute, we will divide 57 by 60, because there are 60 minutes in an hour, and there were 57 miles traveled in a hour. This gives you the rate of miles per minute (0.95), and to get the answer for 20 minutes, just multiply 0.95 by 20 (19 miles).
