kari74 [83]

Answer:

53.2 kg

Step-by-step explanation:

Let E represent Esther's weight. Then Henry's weight is E/2, and David's weight is E-5.2. Their average weight is ...

((E-5.2) + E + (E/2))/3 = 42.6

2.5E -5.2 = 127.8 . . . . . . . . . . multiply by 3, simplify

2.5E = 133 . . . . . . . . . . . . . . . . add 5.2

E = 133/2.5 = 53.2 . . . . kg

Esther's weight is 53.2 kg.

y = 12x represents the gallons of paint used in x hours.

Step-by-step explanation:

CJ uses 3 gallons of paint in 15 minutes,

15 minutes = 3 gallons

1 minutes = $\frac{3}{15} = \frac{1}{5} \ gallons\\$

1 hour = 60 minutes

Gallons of paint used in 1 hour;

1 hour = $\frac{1}{5}*60=12\ gallons$

CJ uses 12 gallons of paint in 1 hour.

Gallons of paints used = y

y = 12x represents the gallons of paint used in x hours.
