8* x + y + y; use x=9, and y = 10
Answer:
If we have 8 * x + y + y:
We have to first substitute in x and y where they should be:
=> 8 * 9 + 10 + 10
According to the order of operations(PEMDAS(parenthesis, exponents, multiplication, division, addition, subtraction, multiplication and division is you go from left to right order, and same with addition and subtraction.)), we do the multiplication first(8*9):
=> 72 + 10 + 10
Now we just add them up:
=> 92
Solve the system. 3x - 2y = 12 and 3x - 3y = -2
Answer:
x = 4 + -0.6666666667y x = 1 + yStep-by-step explanation:
Simplifying
3x + 2y = 12
Solving
3x + 2y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
3x + 2y + -2y = 12 + -2y
Combine like terms: 2y + -2y = 0
3x + 0 = 12 + -2y
3x = 12 + -2y
Divide each side by '3'.
x = 4 + -0.6666666667y
Simplifying
x = 4 + -0.6666666667y
Simplifying
3x + -3y = 3
Solving
3x + -3y = 3
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
3x + -3y + 3y = 3 + 3y
Combine like terms: -3y + 3y = 0
3x + 0 = 3 + 3y
3x = 3 + 3y
Divide each side by '3'.
x = 1 + y
Simplifying
x = 1 + y

Mr. Lopez wrote the equation 32 g + 8 g minus 10 g = 150 on the board. Four students explained how to solve for g.
Alyssa: “I added 32 and 8 to get 40, subtracted 10 to get 30, and then subtracted 30 from 150 to find the value of g, which is 120.”
Rahul: “I added 32, 8, and 10 to get 50, and then I subtracted 150 to find the value of g, which is –100.”
Toni: “I subtracted 18 from 32 to get 14, which I then divided into 150 to find the value of g, which is 10 and StartFraction 5 Over 7 EndFraction.”
Wilhem: “I added 32 and 8 to get 40, subtracted 10 to get 30, and then divided both sides by 30 to find the value of g, which is 5.”

Jackson went to a store that was selling everything at 25% off! The price of a coat that he bought was $34.50 after taking off the discount. What was the original price of the coat?
Given:
The price of coat after discount of 25% is $34.50.
To find:
The original price of the coat.
Solution:
Let x be the original price of the coat.
Price of coat after discount = Original price - 25% of original price
On substituting the values, we get
[tex]34.50=x-\dfrac{25}{100}\times x[/tex]
[tex]34.50=x-0.25x[/tex]
[tex]34.50=0.75x[/tex]
Divide both sides by 0.75.
[tex]\dfrac{34.50}{0.75}=x[/tex]
[tex]46=x[/tex]
Therefore, the original price of the coat is $46.

Answer: -9/4
Step-by-step explanation:
First you subtract 7/2 from both sides of the equation
3x + 7/2 - 7/2= x - 1 - 7/2
Next what you do is simplify one you add 3 + 7/2 which is 9/2
Then you subtract X from both sides of the equation
3x - x = x - 9/2 - x
combine the terms
2x = -9/2
divide both sides of the equation by the same term
2x/2 = 9/2 / 2
cancel the terms and divide the numbers
x=-9/4

During a sale, every item in a store is 80% of its regular price. 1.If the regular price of a T-shirt is$10, what is its sale price? 2.The regular prices of five items are shown here. Find the sale price of each item
Answer:
It could be $12.05.
Step-by-step explanation:
I don't really understand it but, i did 80% divided by 10 but it would be $0.08 and i don't think it would be that so i did 10 divided by 80 and it came out as $12.05.
i haven't done that in school so im not sure

15 16 18 01:34:02 Kate begins solving the equation (6x – 3) = }(6x – 4). When she adds 2 to both sides, the equation 4x = 3x results. Which solution will best illustrate what happens to x ? Her work is correct and is shown below. (6x – 3) = (6x – 4) O The equation has infinite solutions. O The equation has one solution: x = 0. 4x - 2 = 3x - 2 O The equation has one solution: x = 4 O The equation has no solution.
The true statement is that the equation has one solution; x = 0
How to determine the equation solution?We have:
2/3(6x – 3) = 1/2(6x – 4)
When 2 is added to both sides, the equation becomes
4x = 3x
Subtract 3x from both sides of the equation
x = 0
Hence, the equation has one solution; x = 0
