Peppermint to chocolate is 5:3, so5p=3c, and peppermints to gummies is 3:4, so 3p = 4g.
5p = 3c
*3 *3
15p = 9c
---------------
3p = 4g
*5 *5
15p = 20g
---------------
15p = 9c
15p = 20g
9c = 20g, so chocolates to gummies is 9:20.
Answer:
-3x-1y
Step-by-step explanation:
5x - 3y⇒ -2(4x-y)
⇒-2(4x - y) = -8x +2y
5x - 3y -8x + 2y
<u>Combine like terms:</u>
5x- 8x= -3x
-3y +2y = -1x
<u>-3x - 1y</u>
Answer:
X = 4
Step-by-step explanation:
24 - 12x + 24 = 8x - 32
48 - 12x = 8x - 32
+12x. +12x
48 = 20x - 32
+32. +32
80 = 20x
divide both sides by 20
x = 4
Answer:
The students mistake was that he took 31% of the new price and added it to the new price. He should have taken 69% of his new price and added it to his new price. The original price was $375.36
Step-by-step explanation:
Lets work it out and compare our work. Since its 31% off, the formula we need to use is original times percent off equals the new price. Let x equal the original.
x*.69=259
Divide both sides by .69
(x*.69)/.69=259/.69
Divide
x=375.36
The original price was $375.36
The students mistake was that he took 31% of the new price and added it to the new price. He should have taken 69% of his new price and added it to his new price.
