Each car in a rental fleet is either red or white, and there are 75 cars total. There are three more white than twice the number of red cars. How many cars are white?
How do I solve this?
W = 2R + 3
R + W = 75
Substitute 2R+3 for W in the second equation and solve for R. Insert that value into the first equation to solve for W.
Given that rectangle MNOP rectangle STUV, what is the length of TU?
First, do your own post rather than adding on to another.
Second, you have insufficient data.
