Yes. Both are at a right angle and both have the little tick on line AB and XY, so they must be congruent.
Equation 1) 10x + 2y = 30
Equation 2) 4x + y = 4
Multiply all of equation 2 by 2.
2) 2(4x + y = 4)
2) 8x + 2y = 8
1) 10x + 2y = 30
Subtract equations from each other.
-2x = -22
Divide both sides by -2.
x = -22/-2
x = 11
B) x = 11

(6xy - 8x^2)/2x
=
2x(3y - 4x)
Answer:
50 minutes
Step-by-step explanation:
1/2 hour = 30 minutes
1/3 hour = 20 minutes
30 + 20 = 50 minutes
