Answer:
C = 5
Step-by-step explanation:
Distribute the 3
3c - 18 + 6c = 27
Adding like terms
9c - 18 = 27
Add 18 to both sides
9c = 45
Dividing both sides by 5
C = 5
Answer: the answer is 8 rows
Step-by-step explanation: If there are 112 students and they need to be put in rows of 14 you must divide 112 by 14 to get the amount of rows.
3x + 40 + x = 180
-40. -40
——————————-
4x. 140
—. ——-
4. 4
x = 35
Just remember BODMAS, which B= brackets O= Order D= Division M= Multiply A=Addition and S=Subtract
So first you solve the brackets so 44+22 is 66
So 66-4+12 so 66-4 is 62
62+12 is 74
So now you have got 74 divided by 2 which is 37
Hope this helps xx
