Answer: 15 hours
Step-by-step explanation:
Total cost of TV = $252, Savings= $87. So, she will require, $252-$87 = $165 to buy TV.
Also, it's given that, she gets paid $11 per hour.
Therefore, she will require 165/11 hours = 15 hours to buy new Tv at the wage rate of $11/ hour.
Step-by-step explanation:
We have that point A is at 3.
This is 3 units to the right of 0 on the number line.
The point that is opposite of A should be 3 units to the left of 0.
That point will be at -3.
Therefore you have to choose the point that is on -3.
It should be similar to one in the attachment.
3(2x+2)=3x-15
mutiply the bracket by 3
(3)(2x)(3)(2)= 6x+6
6x+6= 3x-15
move 3x to the other side
sign changes from +3x to -3x
6x-3x+6= 3x-3x-15
6x-3x+6= -15
3x+6= -15
move +6 to the other side
sign changes from +6 to -6
3x+6-6= -15-6
3x= -21
divide by 3 for both sides
3x/3= -21/3
x= -7
Answer: x= -7
3 (n + 1) (expression)
3n + 3 (expression simplified)
