12x-20=64

12x=84

X=7

Basically, add -20 to 64 to get 84. You are then left with 12 so divide 84 by 12 to get 7. Hope this helped!

X = 12y - 20

y = 12y

Y is obviously greater than 20 when you multiply it by 12, so that's a hint.

x = 42

y = 22

3.5 • 12 + 22 = 64

I hope this helped you!

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.
Nonamiya [84]

Answer:

black = 0.28

white = 0.22

pink = 0.24

blue = 0.26

Step-by-step explanation:

Jason and his friend spun the spinner 100 times total. So for each time landed on a color, it can be counted as one percentage (for example, black had a 28% frequency). To transfer percentages to decimal form, simply bring the decimal point over by two spaces (28 becomes 0.28, something like 4 would become 0.04). Hope this helps! Feel free to ask any questions!

A blazer cost $38 and you pay $39.90. how much is the sales tax rate
geniusboy [140]
To find the percentage, you divide the new price ($39.90) by the original price ($38), and the multiply it by 100 to change the answer from a decimal to a percentage:

39.90 / 38 x 100 = 105

So 39.90 is 105% of 38

To get our final answer, subtract this by 100%

105 - 100 = 5%

ANSWER: So the percentage increase of the price is 5%  ($1.90)
