1. Kim's age is twice that of her sister. When you add Kim's age to her sister's age, you get 24. How old is each

Andre45 [30]

Answer:

a) Let Kim's age be k, then Kim's sister's age is k/2

k+ $\frac{k}{2}$ =24

b) k+ $\frac{k}{2}$ =24

1 $\frac{1}{2}$ k=24

k=16

$\frac{k}{2}$ =8

Kim's age is 16 while her sister's age is 8.

Find the value of each variable. <br> X=?

Effectus [21]

x=3

Step-by-step explanation:

The equation is x² + 5x = 24, so 3² +15 would be the perfect match. This is because 9+15=24.
