X - 2y = 10
3x - 5y = 4

y = -26

x = -42

Step-by-step explanation:

3x - 5y = 4

x - 2y = 10

x - 2y = 10

x = 2y + 10

3x - 5y = 4

3(2y + 10) - 5y = 4

6y + 30 - 5y = 4

y + 30 = 4

y = -26

x - 2y = 10

x - 2(-26) = 10

x + 52 = 10

x = -42

Check:

x - 2y = 10

(-42) - 2(-26) = 10

-42 + 52 = 10

10 = 10

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

the square root of what number? if you add that, then someone will probably answer the question.
