You can do 15-5=10 and then you have 3 left to subtract. Which means 10-3=7

3 dimes= 30 cent
4 pennnies= 4
30+4= 34 cents
It’s (-8z^2 +8x +4y -2z)

The direct variation equation is:
d=kt
where d is the distance that the giraffe travels
k is the constant of variation
and t is time
Now we are told that the giraffe can travel 800 ft in 20 seconds, so we can solve for the constant of variation (k)
800=k(20) divide both sides by 20
k=40-------------and the units are ft per sec
So now we can write
d=40t
ck
d=40t
800ft=40*20 ft
800 ft= 800 ft
Hope this helps!
