Answer:
(-7, -8)
Step-by-step explanation:
To start we have to isolate a variable to get an equation for it.
Let's get an equation for x from the first equation:
x - 2y = 9
x = 2y + 9
Now that we know what x is in terms of y, lets plug it into our second equation:
3(2y + 9) - 5y = 19
6y + 27 - 5y = 19
y + 27 = 19
y = -8
Now that we know what y equals, let's plug it into our first equation and solve for x:
x - 2(-8) = 9
x + 16 = 9
x = -7
Now that we have x and y, we make our ordered pair, in terms of (x, y):
(-7, -8)

Answer:
3.14 square units
Step-by-step explanation:
Circumference of a circle = 2πr
2πr = 6.28
r = 6.28/2π
r = 3.142/π
Area of a circle = πr^2
slot in the value of r
Area of the circle = π( 3.142/π)^2
" = π(9.87/ π^2)
" = 9.87/π
π = 3.14
Area of a circle = 9.867/ (3.14)
" = 3.14 square units

Answer:
-22.28
Step-by-step explanation:
Let the number to be subtracted from 50/29 to get 24 to be x
So this can be written as : 50/29 - x =24 ----collect like terms as
50/29 - 24 = x
1.72 -24 = x
-22.28 = x
So to check the answer;
50/29 -{x} = 24
50/29 - {- 22.28} = 24
1.72+ 22.28 = 24 ---correct.
