C+2c+12=75
what is the value of c?

C + 2c + 12 = 75

Combine like terms:

3c + 12 = 75

Subtract 12 to both sides:

3c = 63

Divide 3 to both sides:

c = 21

Add like terms1c+2c=3c
3c+12=75
subtract 12 from both sides
3c=63
divide both sides by 3
c=21

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
