Answer:
92º
Step-by-step explanation:
(2x-2)º=x+45º
2x-2=x+45
2x-x=45+2
x=47
____________
22x-2=2(47)-2=92º
3x + 3y + 6z = 9
2x + 1y + 3z = 7 ⇒ 6x + 6y + 8z = 6
1x + 2y - 1z = -10 6x + 6y + 8z = 6
4z = 12
3x + 3y + 6z = 9 4 4
2x + 1y + 3z = 7 ⇒ 0x + 0y + 4z = 12 z = 3
1x + 2y - 1z = -10 2x + y = -2
2x + (-4) = -2
2x - 4 = -2
+ 4 + 4
2x = 2
2 2
x = 1
(x, y, z) = (1, -4, 3)

i hope this helps!
explanation:
part a.) 16 + 5m
part b.) if you walked 15 miles, you would earn $91. work:
16 + 5m
16 + 5(15)
16 + 75
91

Answer:
r = π C , C = 12 − x , t h e n r = π ( 12 − x ) = 12 π − π x
Step-by-step explanation:
So cutting the wire of 12 m in length into two pieces, x and 12-x. The x side will be made into the square so that the square has sides x/4 and an area of (x/4)^2. This means the length of the wire 12-x will be the circumference of the circle. So if: r = π C , C = 12 − x , t h e n r = π ( 12 − x ) = 12 π − π x i hope this is correct
