Mathematics
1 answer:
emmainna [20.7K]2 years ago
7 0

Answer:

85-86%

Step-by-step explanation:

Make it an equation

You want to find the percent out of a hundred, so 42 is 100 since it is all of the questions and 36 is the unknown percent X

36/42 = X/100

36             X

42             100

Cross multiply

Do math and solve for X

36 x 100 = 42 x X

3600=42X

X=85.71

X~4y=11 , 5x~7y=~10 system of equation using elimination to solve
tino4ka555 [31]
1x + 4y = 11 ⇒ 5x + 20y = 55
5x - 7y = -10 ⇒ <u>5x -   7y = -10</u>
                                 <u>27y</u> = <u>65</u>
                                  27     27
                                     y = 2¹¹/₂₇ 
                     x + 4(2¹¹/₂₇) = 11
                         x + 8²²/₂₇ = 11
                         <u>    - 8²²/₂₇  - 8²²/₂₇
</u>                                     x = 2⁵/₂₇
                              (x, y) = (2⁵/₂₇, 2¹¹/₂₇)
