which expression is equivalent to 7(xy)
a.7x+y
b.7x-y
c. x(7y)

Pretty sure it's C if i'm wrong sorry ;;

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
