We are trying to find miles/hour, which shows that we are going to be dividing the total number of miles by the total number of hours. Thus, in this case, the miles/hour rate will be:

He drove 40 miles in one hour.
She will use 42 purple beads.
Explanation
We will use a proportion to solve this.
The ratio of blue to purple beads is 4:3, or 4/3.
We know she uses 56 blue beads and an unknown amount, x, of purple beads. This gives us 56/x.
Together, we have
4/3 = 56/x
Cross multiply:
4*x = 3*56
4x = 168
Divide both sides by 4:
4x/4 = 168/4
x = 42
Answer:
one , i guess....
because the conjecture is only true if it satisfies all the cases.
Answer: f(x)=(x+2)(x−4) because you can see when each factor is equal to zero.
Step-by-step explanation:
No because 3 x 4 = 12 and 8 x 4 ≠ 24
