Add 5x+2x+3x you get 10x bring the 20 down set it equal to 180
you have 10x+20=180
subtract 20 from 180 which gives 160
So now you have 10x=160
divide 10 by both sides you get x=16

den301095 [7]

Answer:

16%

Step-by-step explanation:

To find what percent of the regular cost is saved by renting a movie on a Tuesday, we must do 0.49/3.00. This helps us find the decimal point to convert into a percentage. 0.49/3.00 is equal to 0.163333333333 . And 0.163333333333  converted into a percentage is approximately 16%.

Hope this helps and if it does, don't be afraid to rate my answer as well as maybe give it a "Thanks"? (Or even better a "Brainliest")

Solve for x and y! Help plz
RoseWind [281]

Answer:

x = 20

y = 19

Step-by-step explanation:

(2x - 3)° + (3x - 7)° = 90° (complementary angles)

(2x - 3 + 3x - 7)° = 90°

(5x - 10)° = 90°

5x - 10 = 90

5x = 90 + 10

5x = 100

x = 100/5

x = 20

2y - 1 = 2x - 3 ( vertical angles)

2y = 2x - 3 + 1

2y = 2x - 2

2y = 2*20 - 2 (plug x = 20)

2y = 40 - 2

2y = 38

y = 38/2

y = 19
