Le help needed with like terms and distributive property
Rashid [163]
Like terms would be taking all of the ones with a and getting them alone, all of the ones with b alone, and all plain numbers alone to simplify

1) 2a+3-5a+8b
****= -3a+8b+3****
take 2a-5a and that is your answer

2) 6a+rs-4a+6rs
=2a+rs+6rs
combine the a's 6a-4a
****=2a+7rs****
1rs+6rs combine rs's and that's it :)

**** is the answers

Translate this sentence into an equation. 62 is the sum of 12 and Chrissy's age. Use the variable c to represent Chrissy's age.
Greeley [361]
62= 12+c

Which your answer is 50 cause if you take 62 and subtract it to 12 it's 50. So 50 + 12 = 62
