Alex's dog weighs 7 times as much as her cat. Together, the two pets weigh 72 pounds. How much does Alex's dog weigh?

raketka [301]

D=dog's weight
c=cat's weight
d=7c
d+c=72
sub 7c for d
7c+c=72
8c=72
divide both sides by 8
c=9
d=7c
d=7(9)
d=63
dog=63lb

Hey there!

<h2>ANSWER: $f=-16$ </h2><h2>EXPLANATION:</h2>

$\frac{f}{4}-5=-9$

Simplify both sides and you get:

$\frac{1}{4}f-5=9$

Now add 5 to both sides and you get:

$\frac{1}{4}f=-4$

Now you have to multiply both sides and you get:

$f=-16(ANSWER)$

Hope this helps!
