Answer:
it is 11.25 dollars per hour.8x=90 which is 11.25
What is the solution to the system?
y = 4x + 20
8x - 2y = -20
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.

Use the formula A=bh, where A is the area, b is the base length, and h is the height of the parallelogram, to solve this problem.
Ms. Su zie ordered some tiles for her kitchen in the shape of a parallelogram. Each tile has an area of 108 square inches. The base of the tile measures 12 inches long.
What is the height of the tile?

Answer:
big
Step-by-step explanation:
pp energy
Answer:
9 inches
Step-by-step explanation:
A = bh
A = 108
b = 12
108 = 12h
108/12 = h
9 = h so the height is 9 inches

Tell whether the ratios form a proportion.
1 to 0.4 and 9 to 3.6
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}

parallel
I’ll give Brainliest. Due Soon.
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 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?
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.

Write your own real-world scenario where the Pythagorean Theorem can be applied to find a missing piece. You may choose to write a problem that is two- or three-dimensional in nature. Be sure that you will be able to draw a diagram of your scenario.
Write out your problem and submit it for Part 1. Be sure to end your scenario with a question.
Answer:
Supposed that you needed to know the diagonal distance from opposite corners of a rectangular prism.
d^2=x^2+y^2+z^2 where x, y, and z are the dimensions of the prism, or rectangular "box"
If the box has a width of 10, depth of 20, and a height of 30 then you have:
d^2=100+400+900
d^2=1400
d^2=100*14
d=√(100*14)
d=10√14 units
d≈37.42 units (to nearest hundredth of a unit)
You might need this information to determine the most amount of space necessary to allow this box to pass through in any orientation...as the diagonal is the maximum dimension of the box.
I did a three-dimensional problem as the Pythagorean Theorem is often used only for two-dimensional problems in early mathematics.

Math problem:
43 ÷ (7 − 3) × 2.
Answer: 21.5
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
