Answer:
-2
Step-by-step explanation:
i just took the test
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.

Answer:
3.2
Step-by-step explanation:
first expand the bracket, (2^3 -6 )= (2 x 2 x 2) - 6= 8 - 6 = 2
so, 6.4/2= 3.2
[[Please explain]] The length of a spring varies directly with the mass of an object that is attached to it. When a 30-gram object is attached, the spring stretches 9 centimeters. Which equation relates the mass of the object, m, and the length of the spring, s?
O s=3/10m
O s=10/3m
O s=3/10s
O s=1/30s
Answer:
The required equation is [tex]s =\frac{3}{10} m[/tex]
Step-by-step explanation:
Given: The length of a spring varies directly with the mass of an object that is attached to it. When a 30-gram object is attached, the spring stretches 9 centimeters.
To find : Which equation relates the mass of the object, m, and the length of the spring, s?
Solution :
Let the mass of the object m,
Length of the spring s,
When a 30-gram object is attached, the spring stretches 9 centimeters.
i.e, the times length of the object is attached to spring is The length of a spring varies directly with the mass of an object that is attached to it.
According to question,
i.e, length of the spring is 3 by 10 times the mass of the object.
Therefore, The required equation is

When you have powers in this fashion, all we need to do is multiply the two to get our answer.
Now we can solve:

What is 5x-y=1/4 in slope intercept form? PLEASE give me step by step explanation and why you did what. Thank you! ❤
Answer:
y=5x-1/4
Step-by-step explanation:
The slope-intercept form would be y=mx+b, where y would be on one side. In this case, we would have to move y to one side. You can add y on both sides to move it on the right. Then, you would subtract 1/4 on both sides to move it to the left so that y is on its own side. Then the equation would equal y=5x-1/4, where 5 = m and -1/4 = b.
Answer:
The calculation to your equation is:
Y=5x-1/4
Step-by-step explanation:
An online media service offers video and music downloads. Each download of a song costs $1. Each download of a video costs 5 times as much as the song download. You have a credit of $70. How many songs can you purchase after buying 12 videos?
Answer:
You can purchase 10 songs after buying 12 videos.
Step-by-step explanation:
Step 1 - Find out how much downloading a video costs. If the cost of a video download is 5 times as much as a song download costs, and a song download is $1, then you'd have to multiply 5 x $1, which equals 5. So downloading a video costs $5.
Step 2 - Find how much it costs to buy 12 videos by multiplying the cost of 1 video to how many you bought, 12. We already found out 1 video costs $5, so that would 12 x $5, which equals $60. That means those 12 video downloads costed you $60 dollars.
Step 3 - Find out how many songs you can buy with your remaining credit. If you already payed $60 dollars worth of videos, then you only have $10 dollars left to spend because $70 - $60 is $10. So if every song costs $1 dollar, then you'd be able to purchase 10 more songs until you reach your credit, $70 dollars.
Use the given data to find the equation of the regression line. Round the final values to three significant digits, if necessary.
= 150.7 – 6.8x
= 140.4 – 6.2x
= –150.7 + 6.8x
= –140.4 + 6.2x
Answer: 150.7

how can you find the product of positive and negative decimals
(I have attached an example for reference)
1) Product means multiply, so we will multiply the decimal numbers.
2) First multiply both the numbers just the way you multiply two whole numbers.
3) note that WHILE multiplying you DON'T put the decimal point. Put the decimal point once you get your FINAL answer.
4) Once multiplied, count the total number of places after the decimal in both the numbers which were given. i.e, in the example it's 2 decimal places, one decimal place in 24.5 and one in 3.2, which means the total decimal places here are two.
5) now in your answer, start counting the decimal places from the right side of the number. For example in 7840, we start counting two decimal places from the right side of it and stop at 4 and put a decimal point there. This way we get 78•40.

2. HOW MANY GALLONS OF WATER ARE REQUIRED TO PRODUCE 15 POUNDS OF CHOCOLATE? WRITE AND SOLVE AN EQUATION. LET 'g' BE THE NUMBER OF GALLONS.
(hidden water cost/ 1 pound of chocolate = 3,170 gal - 1 ream of paper = 1,321 gal -1 gallon of milk = 880 gal - 1 cotton t-shirt = 713 gal - 1 hamburger = 660 gal)
3. Extension : The owner of a company has a goal to reduce the company's water footprint by 100,000 gallons in one year. He estimates that if the company reduces its yearly need for paper by 80 reams, he will meet his goal. Could the owner have estimated correctly? Justify your answer.
Does anyone have any ideas for multiplying 249 times 398 quickly and mentally? Everything online is too complex.
Answer:
So, the first solution is a calculator but sometime we don't have a calculator so, do
200 X 300 = A
40 X 90 = B
9 X 8 = C
then add just do multiplication from there like
A + B = D
D + C = E
Then your finally answer would be E
Hope that helps that's the way I do math quick in my head
