Denise is 7 years younger than Alma. Misty is twice as old as Alma. All together, they have
an age of 37. How old is Denise?

Denise is 4 years old

Step-by-step explanation:

Let the age of Denise be x years.

We are told that Denise is 7 years younger than Alma. Thus, Alma's age is; (x + 7)

Now, misty is twice as old as Alma. Thus age of misty is; 2(x + 7).

If their total ages are 37,then we can say;

x + (x + 7) + 2(x + 7) = 37

x + x + 7 + 2x + 14 = 37

2x + 7 + 2x + 14 = 37

4x + 21 = 37

4x = 37 - 21

4x = 16

x = 4

at home andrea has 1 2/3 kilograms of rice

step-by-step explanation:

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
