Find the solution for x and y
2 answers:
Answer:
Below
Step-by-step explanation:
Here is how to solve this by elimination
Divide both sides by 3
-7x - 2y = 14
2x + 2y = 6
Eliminate one variable by adding the equations
-5x = 20
Divide both sides by -5
x = -4
Sub in x to -7x -2y = 14
-7x (-4) -2y = 14
y = 7
So, ( x, y ) --> ( - 4, 7 )
Hope this helps! Best of luck <3

1/10 because amongst 10 balls there is only one 10th ball there by making only one possible chance of getting ball no 10
BD = BC + CD
7x - 10 = (4x - 29) + (5x - 9)
7x - 10 = 9x - 38
2x = 28
Ans: x = 14
BC = 4x - 29
= 4(14) - 29
= 27
Ans: BC = 27
CD = 5x - 9
= 5(14) - 9
= 61
Ans: CD = 61
BD = 61 + 27
= 88
Ans: BD = 88
Answer:C
Step-by-step explanation:
The answer is 14. You would get x to the second power and 196. Then you have to square root both sides and you would get x=14.
Answer:
A, 40.16
Step-by-step explanation:
cosθ = adjacent (BC) / hypotenuse (AB)
cos 17° = BC / 42
BC = 40.16
