Answer:
You must drive 5 hours
Step-by-step explanation:
First we have to calculate how much we have to cover
v = velocity = 65 mi/h
t = time
d = distance
v = d/t
t = d/v
d = 700mi - 375mi
d = 325mi
t = d/v
t = (325mi) / (65mi/h)
t = 5h
The equation would then look like this:
t = (700mi - 375mi) / (65mi/h)
I think the question is
Find the value of c so that (x-5) is a factor of the polynomial
The other factor is going to be some quadratic. We can say a few things about its coefficients but let's start by saying in general it's
Equating respective coefficients,
so we get
Answer: -37

Answer:
a) 3x-5=16
b) 30cm
Step-by-step explanation:
a) 5(x-1)=2(x+8)
5x-5=2x+16
5x-2x-5=16
3x-5=16
b) solving the equation gives x=7
put x=7 into first line, 5(7-1)=30cm
to check we can place it into second one as well
2(7+8)=30cm
20 - 4 - 2 = 14. A negative number is just like subtracting it.
