NED WEIGHS 1 1/2 TIMES AS MUCH AS JILL AND TOM WEIGHS 15 KILOGRAMS MORE THAN JILL IF THEIR COMBINED WEIGHT IS 190 KILOGRAMS HOW MUCH DOES EACH PERSON weigh?

Sagot :

We can write it down as:

Jill = x
Ned = 1,5 * x
Tom = x + 15

So:

190 = x + 1,5 * x + x + 15
190 = x + 1,5x + x + 15
190 = 2x + 1,5x + 15
190 = 3,5x + 15                    / - 15 (both sides)
175 = 3,5x                           / ÷ 3,5 (both sides)
x = 50

So:

Jill = 50 kg
Ned = 1,5 * 50 = 75 kg
Tom = 50 + 15 = 65 kg
