Answer:B
Step-by-step explanation:
(4x - y)/(2y + x) when x = 3 and y = 3 is
(4(3) - 3)/(2(3) + 3) = (12 - 3)/(6 + 3) = 9/9 = 1
Answer:
$0.22 per inch

Answer:
28
Step-by-step explanation:
the triangles are congruent, so we know that 2x + 10 = 3x + 1
using basic algebra we find that x is equal to 9
to find angle q, just plug the x value, 9, to 3x + 1, which gives us 3 × 9 + 1, or 28
Hope this helps! :)
Answer:
(x, y) =(2,-3)
Step-by-step explanation:
4x+3y=-1
3x-9y=33 /:3
4x+3y=-1.....(1)
x-3y=11... (2)
(1)+(2): 5x=10
x-3y=11
x=10/5
x-3y=11
x=2
2-3y=11
x=2
-3y=11-2
x=2
-3y=9
x=2
y=9/(-3)
x=2
y=-3
(x,y)=(2,-3)
