Answer:
/ Solve equation [2] for the variable y
[2] 7y = 12x + 17
[2] y = 12x/7 + 17/7
// Plug this in for variable y in equation [1]
[1] 9x - 2•(12x/7+17/7) = -3
[1] 39x/7 = 13/7
[1] 39x = 13
// Solve equation [1] for the variable x
[1] 39x = 13
[1] x = 1/3
// By now we know this much :
x = 1/3
y = 12x/7+17/7
// Use the x value to solve for y
y = (12/7)(1/3)+17/7 = 3
Solution :
{x,y} = {1/3,3}
Step-by-step explanation:
Answer:
52pi
Step-by-step explanation:
You need the area of the large grey circle, minus the white circle, plus the small grey
Large grey = 8^2 * pi = 64pi
White = 4^2 * pi = 16pi
Small grey = 2^2 * pi = 4pi
64pi - 16pi = 48pi, 48pi + 4pi = 52pi
All of your answers are correct
Answer:
is that the number in the middle = then more the -3 to 2x add in you get 1 being y=1 so 1 -3 is 2x
