A wooden bench was originally priced at $50 but went on sale for 20% off. If Presley bought the wooden bench and paid a 5% sales tax, how much did he pay in total?

Answers

Answer:

$42.00

Step-by-step explanation:

20% OF  50 = 40

Before Tax Price: $40.00

Sale Tax: 5.00% or $2.00

After Tax Price: $42.00

Answer:

$42

Step-by-step explanation:

To get the new bench price, you multiply 50 × 0.2, which gets you 10, then you subtract 50-10, which is 40, and $40 is the price of the bench on sale. (You could also do 50 × 0.8 to avoid a step and still get the same answer).

You then take 40 and multiply is by 0.05 to get the tax, which would be $2. From here, you add 40+2 to get $42, the amount of money Presley paid for the bench.

Answer:

a and b are parallel, and so are t and s.

Step-by-step explanation:

By U-angles, a and b are parallel, because 108 + 72 = 180 degrees.

By corresponding angles and F-angles, t and s are parallel, because 108 = 108 degrees.

A and b are parallel because straight lines add up to 180!

What is the solution to the system?

y = 4x + 20
8x - 2y = -20

Answers

Answer:

-no solution-

Step-by-step explanation:

When solving problems for systems of equation. You first want to make one of the equations equal to one variable on a side of the equation. In this case, we already have an equation that equals a variable on one side: y = 4x + 20.

you plug in that variable to the other equation

8x - 2(4x + 20) = -20

and then you just solve the equation from there.

8x - 8x + 20 = -20

but by just looking at this, there will be no solution because 8x-8x makes the variable x disappear and 20 does not equal -20.

The answers would be
1. Y=-5
2. 2.5

Step-by-step explanation:

Answer:

21.50

Step-by-step explanation:

43 ÷ (7 − 3) × 2

According to order of operations you would do 7 - 3 first which gets you to 4.

43 ÷ 4 × 2

Now you would do 43 ÷ 4 which is 10.75 so next...

10.75 × 2

You should get an answer of 21.50

Tell whether the ratios form a proportion.

Answers

Answer:

no?  cause one is negative and the other is positive and I'm guessing they both have to be the same

Step-by-step explanation:

3  =  x

x         3

These are fractions btw

Cross multiply:

3 * 3 = x * x

Simplifying

3 * 3 = x * x

Multiply 3 * 3

9 = x * x

Multiply x * x

9 = x2

Solving

9 = x2

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1x2' to each side of the equation.

9 + -1x2 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0

9 + -1x2 = 0

Add '-9' to each side of the equation.

9 + -9 + -1x2 = 0 + -9

Combine like terms: 9 + -9 = 0

0 + -1x2 = 0 + -9

-1x2 = 0 + -9

Combine like terms: 0 + -9 = -9

-1x2 = -9

Divide each side by '-1'.

x2 = 9

Simplifying

x2 = 9

Take the square root of each side:

x = {-3, 3}

The answer is 3=x I think

Step-by-step explanation:

If you look at the graph, you will notice that points aren't correct. The first point (200,207), the point is plotted as (207,200). The numbers are switched. The point is at 200 on the y axis and at 207 on the x axis, which is reversed from what the point should be.
