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.

8*9
Answer: LCD = 72
Step-by-step explanation:
Rewriting input as fractions if necessary:
1/8, 1/12, 7/18
For the denominators (8, 12, 18) the least common multiple (LCM) is 72.
LCM(8, 12, 18)
Therefore, the least common denominator (LCD) is 72.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
1/8 = 1/8 × 9/9 = 9/72
1/12 = 1/12 × 6/6 = 6/72
7/18 = 7/18 × 4/4 = 28/72

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.
Answers
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.

find the length of of a 100-yard football field in meters. Use 1 yard = 3 feet
and 1 meters ≈ 3.28 feet round to the nerest tenth.
(≈ means about)
Answers
Answer: 91.46m
Step-by-step explanation: The length of 100 yard football field in meters. From the dimension given, 1 yard = 3 feet Therefore, 100 yard = x feet 1 yard = 3 feet 100 yard = x feet X = (100 × 3) / 1 X = 300 feet. But, 1 meter = 3.28feet X meter = 300 feet X = (300 × 1) 3.28X = 91.46m Therefore, 100 yard football field is equal to 91.46m

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.
