please simplify 6(–2y) – 9 + 4(–2y + 6) and include a step by step
Step-by-step explanation:
6(–2y) – 9 + 4(–2y + 6) original equation
-12y - 9 + -8y +24 simplify groups
-20y + 15 combine like terms
Answer:
-20y+15
Step-by-step explanation:
distribute
= 6(-2y) + -9 + (4)(-2y) + (4)(6)
= -12y + -9 + -8y + 24
Combine like terms
= -12y + -9 + -8y + 24
=(-12y + -8y) + (-9+24)
= -20y + 15

x-7(x-2)=10x+9-x i need the answer asap pls
Answer:
x=[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
x-7(x-2)=10x+9-x
x-7x+14=10x+9-x Distribute -7
-6x+14=9x+9 Combine like terms
14=15x+9 Add 6x to both sides
5=15x Subtract 9 from both sides
[tex]\frac{1}{3}[/tex]=x Divide both sides by 15

solve absolute value equation |5c-17| = |3x +11|
9514 1404 393
Answer:
x = 3/4 or 14
Step-by-step explanation:
Assuming your equation is ...
|5x -17| = |3x +11|
it can be rewritten as two equations:
5x -17 = -(3x +11)
5x -17 = 3x +11
__
The solution to the first of these is ...
5x -17 = -3x -11
8x = 6 . . . . . . . . add 3x+17
x = 6/8 = 3/4 . . . divide by 8
The solution to the second equation is ...
5x -17 = 3x +11
2x = 28 . . . . . . . . add 17-3x
x = 14 . . . . . . . . . . divide by 2
The solutions are x = 3/4 or x = 14.
Samantha paid $10 to join an online book club. Then she paid $3 per e-book that she read. She has spent more than $40. How many e-books did she read? Show how you would set the problem up and the answer. * Your answer Submit Jer submit passwords through Google Forms. This form was created inside of River Grove School District 85.5. Report Abuse
Answer:
13/13.3 or 10
Step-by-step explanation:
You said she paid $10 to join, if she spent at least $40, then we subtract 10, then divide 30 by 3 then you would get 10.
If we don't have to subtract and she spent around $40 on only books, it would be 13/13.3
