Answer: 4=y
Step-by-step explanation:
6(7 -3y)+6(y+1)
42-18y+6y+6
48-12y
48/12=4
12y/12=y
4=y
Answer:
$9.70
Step-by-step explanation:
Use PEMDAS:
Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
Problem:
C(x) = 0.06x + 8.50
Substitute x for 20:
C(20) = 0.06(20) + 8.50
Multiply 0.06 and 20:
C(20) = 1.2 + 8.50
Add 1.2 and 8.50:
C(20) = $9.70
The total cost for an order of 20 copies is $9.70
(2x + 2) * x = 264
Solve that for x to get your width
Plug x into "2x + 2" to get your length.
If you need help solving for x let me know
I believe the answer is 311.157055138. That is if i did my math correctly. I hope this helps. Good luck!
3/x=27/54
or,x×27=3×54
or,27x=162
or,x=162/27
or,x=6
