Here’s Why:
We first see that -6x is subtracted from both sides to cancel the +6x out on the left side and combine it with the other like term on the right side, which is 16x. That step is correct.
The next step, we see that -40 is subtracted from 400. THIS IS THE ERROR. To cancel out the 400, then -400 should be taken from it and not -40! This is because the constant of 400 on the left side must be canceled out by -400 from it to make it 0, so that it can combine like terms with the constant on the left side of 150.
So, the error is that -40 was taken instead of -400.

A new club sent out 288 coupons to boost sales for next year's memberships. They provided 5 times as many to potential members than to existing members. How many coupons did they send to existing members?
A.
6
B.
5
C.
53
D.
48
Answers
Answer:
D. 48
Step-by-step explanation:
We don't know the numbers of coupons sent to existing members and to potential members, but we know a relationship between the number.
They sent 5 times as many coupons to potential members as they did to existing members.
Let x = number of coupons sent to existing members.
Then 5x = number of coupons sent to potential members.
The total number of coupons sent was x + 5x = 6x
The total number of coupons sent was 288.
Therefore, 6x must equal 288 giving us an equation with a single variable.
6x = 288
x = 48
Answer: 48

Nina works in as an office receptionist for $15.00 per hour. If her pay is increased to $18.00, then what is her percent increase in pay?
*If you solve this for me can you also put how you got to the answer? just so I can see how you did it :]
Answers
Answer:
20%
Step-by-step explanation:
the number is increased by 3 so you put 3 on 15 and 3/15=1/5=2/10=20/100
The percentage increase in the pay of Nina is 20%.
How to calculate percentage increase?To calculate the percentage increase work out the difference (reduction) between the two figures you are comparing before calculating a percentage drop. Then, increase the result by 100 after dividing the decrease by the initial number.
% Increase = Increase / Original Number × 100
Nina got the initial pay as $15.00 per hour.
After the increment, her pay increased to $18.00.
The total increment = final pay - initial pay
= 18.00 - 15.00
= 3.00
Now, the percentage increase = (3/15)×100
= 20
Therefore, there is the 20% increment for the pay of Nina.

7=3 over 4x what is x?
Answers
Answer:
x=28/3
Step-by-step explanation:
combine multiplied terms into a single fraction
7 = 3x/4
multiply all terms by the same value to eliminate fraction denominators
4 · 7 = 4 · 3x/4
cancel multiplied terms that are in the denominator
4 · 7 = 3x
multiply the numbers
28 = 3x
divide both sides of the equation by the same term
28/3 = 3x/3
simplify
a. cancel that are in numerator and denominator
28/3 = x
b. move the variable to the left
x = 28/3

in order to get that differentiate x²-6x+2
2x-6=0
2x=6
x=3

(-3-√7)² -6(-3-√7)+2≠0
36+12√7≠0

Determine whether the lines AB and CD would be parallel, perpendicular, or neither?
A(-5,3) and B(-5, 7)
What is the slope of AB?
C(1, 9) and D(-10, 9)
What is the slope of CD?
What are the lines? (parallel, perpendicular or neither)
Answers
Answer:
The slope of AB is undefined; the slope of CD is 0; The lines are perpendicular.
Step-by-step explanation:
Line AB would form a vertical line. Slope is Δy/Δx. To go from 3 to 7 (the y-coordinates) you need to go up 4 units. So we would then have Δy/Δx = 4/Δx. To go from -5 to -5 (the x-coordinates) we have to go left or right 0 units. So, Δy/Δx = 4/Δx = 4/0. Anything divided by 0 is undefined. Remember: vertical lines always have an undefined slope.
Line CD would form a horizontal line. To go from 9 to 9 (the y-coordinates) you need to go up or down 0 units. So, Δy/Δx = 0/Δx. To go from 1 to -10 (the x-coordinates) you need to go down 11 units. So Δy/Δx = 0/Δx = 0/1. 0 divided by anything is 0. Remember: horizontal lines always have a slope of 0.
If you picture a horizontal line and a vertical line intersecting, they would both form a right angle when they intersect. By definition, this would make both lines perpendicular.

Amount of sales tax =
Sales tax rate × Price without sales tax
Calculation:
Amount of sales tax =
8% × 30.56 =
8/100 × 30.56 =
8 ÷ 100 × 30.56 =
0.08 × 30.56 =
2.4448 ≈
2.44
(Rounded to a maximum of 2 decimals)
2. Calculate the 'Price with sales tax':
