Ronnie's mass is 2.5 kg less than Heather's mass. The sum of their masses is 97.5 kg. What are their individual masses?

Answer :

Answer: Ronnie weight is 47.5 kg

Heather weight is 50 kg

Step-by-step explanation:

Ronnie weight = x kg

Heather weight = x+2.5 kg

Equation = x + x + 2.5 kg = 97.5 kg

= 2x + 2.5 kg = 97.5 kg

= 2x = 97.5 - 2.5 kg

= 2x = 95 kg

= x = 95/2

= x = 47.5

So, Ronnie’s weight is 47.5 kg and Heather’s weight is 50 kg
