The answer is 3 of each. 3X7=21; 14X3=42, and 42+21= 63.
The answer is forty five.
First you gotta distribute.
4 (1.75y - 3.5) + 1.25y
4 * 1.75 y = 7
4* (-3.5) = (-14)
7y - 14 + 1.25y
Combine like terms
8.25y - 14
Ok so ratios
height:shadow =60:24
fractionify
60/24=5/2
5:2 is ratio
if shadow of tree=4 then what is height
5:2=x:4
multipliby 2
10:4=x:4
x=10
10 feet
