Question 10

Mathematics
1 answer:
Agata [3.3K]3 years ago
5 0

Answer:

A = 21

J = 2A = 42

C= A+5 =26



Step-by-step explanation:

C= christines text messages

J = jims messages

A = ali messages

Jim sent  2 times as many messages as Ali.

J = 2A

Ali sent  5 fewer messages than Christine.

A =C-5

A+5 =C

Christine, Jim, and Ali sent a total of 89 text messages

C+J+A = 89

substitute

C +5= A

A+5 +J+A = 89

combine like terms

2A +5+J = 89

now substitute J = 2A

2A +5+2A = 89

combine like terms

4A +5 = 89

subtract 5 to each side

4A +5-5 = 89-5

4A = 84

divide by 4

A = 21

J = 2A = 42

C= A+5 =26
