Question

Sia weighs 4.5 kg more than raima. If their total weight is 140 kg find sia's weight

Answer 1

Step-by-step explanation:

Let Raima's weight be x .

Therefore Sia's weight = x+4.5

Therefore the equation is ;

(x) + ( x+ 4.5) = 140

2x + 4.5 = 140

2x = 140- 4.5

2x = 135.5

x = 67.75

Therefore Sia's weight is 67.75 + 4.5

= 72.25
