J + m = 84
j = m - 24

m - 24 + m = 84
2m - 24 = 84
2m = 84 + 24
2m = 108
m = 108/2
m = 54...the mom is 54

j = m - 24
j = 54 - 24
j = 30 <==== Jessie is 30

Okay, to begin. Jessie is 24 years younger than her mother. So what we should first do is to subtract every possible age by 24 years. Which leaves us with 30, 6, and 4. Now if the sum of their ages is 84, we need to take all of the possibilities and add them to the other possibilities I've created.

30 + 54 = 84
6 + 30 = 36
4 + 28 = 32

Therefore, Jessie is 30 years old.

yan [13]

Answer: 1 over 20

Step-by-step explanation: If the spinner has 5 parts to it at purple is one of those parts then the spinner has a 1/5 chance of it landing there.

If there are 4 cards and 1 of them are pink then there is a 1/4 chance of picking pink(if done randomly)

So if we mutiply 1/4 and 1/5, we get 1/20

That is how I arrived at my answer of 1 over 20
