To eliminate the y-terms and solve for x in the Fredy steps, by which constants should the equations be multiplied by before adding the equations together? First equation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

i agree because i see the other persons thinking is clear

(8+64)^2= 5184 < answer

step-by-step explanation:

2^3 = 8

4^3= 64

(8+64)^2 = 5184

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
