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.
Answer:
4 meters
Step-by-step explanation:
7-3=4 m
The answer is it should be behind the 7 because you only moved one time in 1.7
78, because you have to do the inverse operation so 80/2= 40 then 40-1= 39 and 39*3 = 78
$365 increased to $428
365/428=1.17
which translates to an 117% increase
