Solve for z.
a(5 - 2) = bx – 8

x=

x =3a/b + 8/b

Rewrite the equation as

bx − 8 = a ( 5 −2).

bx − 8 = a(5 −2)

Simplify a(5−2)

Subtract 2 from 5.

bx− 8 = a ⋅ 3

Move 3 to the left of a.

bx − 8 =3a

Add  8 to both sides of the equation.

bx = 3a +8

Divide each term by  b and simplify.

x =3a/b + 8/b

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.

move it to the other side
