9514 1404 393

Answer:

  72 kph

Step-by-step explanation:

The first sentence tells you the speeds are proportional. So, you can write the proportion ...

  kph/mph = 120/75 = x/45

Multiplying by 45 gives x:

  x = (45)(120/75) = 72

72 kph is 45 mph.

How do i rearrange f-ex=g-hx to get x?
Alborosie

Answer:

x = \frac{g-f}{h-e}

Step-by-step explanation:

Given

f - ex = g - hx

Collect the terms in x on the left side by adding hx to both sides

hx - ex + f = g ( subtract f from both sides )

hx - ex = g - f ← factor out x on the left side

x(h - e) = g - f ← divide both sides by (h - e)

x = \frac{g-f}{h-e}
