The value of the x is -2 after solving the linear equation by using the elimination method.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The linear equations are:
2x+3y=8
6x−5y=−32
3X(2x+3y=8)
6x + 9y = 24
6x−5y=−32
14y = 56
y = 4
x = -2
Thus, the value of the x is -2 after solving the linear equation by using the elimination method.

Mr townsend needs to make 13 pairs of butterfly for customers for a play. Each pair of wings is made with 3/4 yard of fabric. The fabric costs $8 per yard.
You’ll apply properties of multiplication in the following steps to find the total cost of fabric.
1. Use multiplication to write an expression for the amount of fabric needed to make 13 pairs of wings.
2. Multiply the amount of fabric by the price per yard to find an expression for the total costs.
3. Use the associative and commutative properties to rearrange the terms in the expression to make it easier to calculate. Explain why the rearranged expression is easier to work with.

While eating lunch, Vivian ate 65% of the carrots she had in her bag. There were 20 carrots in her bag before she ate any. How many carrots did Vivian have left in her bag after she ate?
Answer:
Vivian would have 7 carrots left to spare if she ate 65% of the carrots in the bag.
Step-by-step explanation: Since 65% of 20 carrots equals 13 carrots, we would do 20 - 13. In which equals 7 so she has 7 carrots left in fer bag
Equation: 20-x=?
Solution: 20 - 13=7

Terms:
A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.

A chef needs to choose a pan that will allow food to cook as quickly as possible for a special recipe and has decided that he will use one of three pans. Each pan has the same dimensions and design but is made of a different type of metal. The chef will design an experiment that will test and rank the thermal conductivity of the pans by cooking a hamburger patty to an internal temperature of 170 °F in each pan on the same stove burner. The thermal conductivity is the rate of transfer of energy in the form of heat over a period of time through a material.
Describe how thermal conductivity can be measured and compared for each of the pans.

Melinda adds $12 to her savings account each week and Marcus adds $14 each week
Melinda adds $2 less than Marcus
Step-by-step explanation:
Melinda:
135 - 75 = 60
60 ÷ 5 = 12
She saves $12 each week
Marcus:
y=14x+25
y=14x5+25
y= 70+25
y=95
95-25=70
70÷5= 14
Marcus saves $14 each week
A 6-pound bag of sugar costs $7.98. What is the unit price?
Answer:
1.33
Step-by-step explanation:
Lets start by making a quick equation:
Total cost is y, or 7.98, with the weight being 6 pounds. We are looking for the unit price, which will be our x.
7.98 = 6x
Divide 6 by both sides:
7.98 / 6 = 6x / 6
This gets rid of the 6 on the right, so we are left with:
1.33 = x
So the unit price is $1.33 per pound.

Write an ordered pair for the point in Quadrant IV that is 4 units away from point s (-1.5, -2.5) on the coordinate plane.
PLS help!
and explain
brainliest
Answer:
(2.5, -2.5)
Step-by-step explanation:
I think that's right. Quadrant IV is when (x, -y)
The point in Quadrant IV that is 4 units away from point (-1.5, -2.5) on the coordinate plane is (2.5, -6.5)
What is the coordinate plane?A coordinate plane is a two-dimensional plane formed by the intersection of two number lines.
Given that, there is a point in quadrant IV that is 4 units away from point (-1.5, -2.5) on the coordinate plane.
If we have a coordinate point (x, -y) in quadrant 4, if the coordinate is 4 units away, the resulting coordinate will be expressed as (x+4, y-4)
(-1.5+4, -2.5-4) = (2.5, -6.5)
Hence, The asked point is, (2.5, -6.5)

Help me PLEASEEEEE I will give brainlyest if the answer is correct
Answer:
See Below
Step-by-step explanation:
Lets look at our numbers:
The balloon is at 1000 feet.
The balloon drops at a constant speed of -4 1/2 per second.
How long will it take to get to 215ft, in seconds, s.
Lets see, if you were to subtract 1000-215, you will get 785.
The balloon needs to drop 785ft to get to 215ft above the ground.
The question asks how long will it take to get below 215ft.
Lets do the math for the descending feet. We calculated that it takes 785ft to hit 215ft above the ground, so, you need to divide 785ft by 4 1/2 to see how many seconds it takes. The answer for this is 174.4, we can make this 174 4/9.
**VERY IMPORTANT** If you use 174 4/9, this equals 215 seconds, it asks for below this, so you can use ANY number for this that it above this number.
Now for the inequality, look at the question, it asks how long will it take to get below, not equal to or more below, meaning that you can cancel out the inequality signs with lines below them. So your answer is 270 > ,

The table shows the attendance at the art show for the past week.
What does the attendance need to be on Saturday to have an average attendance for the week of 30 people per day?
Answer: The correct answer is - 50.
Step-by-step explanation: :)
Answer:
50
Step-by-step explanation:
To calculate the mean, we do the total divided by the number of values. Therefore, to get 30, with 7 values, we need to have a total of 210. Currently, we have a total of 160, so Saturday needs to be 50, because 210-160=50.

Find the volume of a scented candle that is in the shape of a cylinder with a diameter of 16 centimeters and a height of 20 centimeters. Round to the nearest tenth.
*there is no diagram*
Answer:
4021.2 cm³
Step-by-step explanation:
you start by getting the radius, the radius is half the diameter which in this case half of 16 is 8 so 8 is your radius and you already know the height which is 20, now that we have the radius and the height we can start
the formula for finding the volume of a cylinder is πr² · h
so are formula would be π8² · 20 which turns into π64 · 20 which then turns into 1280π or 4021.238...
which you then said we need to round the nearest tenth so 4021.238 to the nearest tenth is 4021.2 cm³

Length: 12 inches
Width: 4 inches
Height: 8 inches
Havana is wrapping a gift whose box's dimensions are all twice the length of the lengths in Jake's box.
How many times larger is the surface area of Havana's box than Jake's box?
Enter your answer as a number, like this: 42
HELP PLEASEEEEEEEE
Answer: 8
Step-by-step explanation: first multiply 12x4x8 for jakes gift. that is 384
then make each of the dimensions twice as large. so havanas dimensions would be. 24x8x16
24x8x16=3,072
last divide 3,072 by 384 and the answer would be 8
Havana's box is 8 times larger.
