x = 6
Step-by-step explanation:
To find x we set up an equation as so:
[tex]\frac{4.5}{x} =\frac{6}{8}[/tex]
Then we solve by multiplying 4.5 by 8 and 6 by x
[tex]6x=36[/tex] Solve for x
[tex]\frac{6x}{6} =\frac{36}{6}[/tex] x = 6
To check our answer when we substitute x or 6 we divide to make sure both sides equal the same number
[tex]\frac{4.5}{6} =\frac{6}{8}[/tex] when divided both equals 0.75
