Answer: 10/35 =55
Step-by-step explanation:
Answer:
x = -13
Step-by-step explanation:
9 - 2x = 35
Subtract 9 from both sides of the equation:
9 - 2x - 9 = 35 - 9
-2x = 26
Divide both sides of the equation by -2:
x= -13
119 times .4 = 47.6

(12z^2 + 25z + 12)/(3z^2 - 2z - 8)
You have to factor it. You know how to factor it right?
(12z^2 + 16z + 9z + 12)/(3z^2 - 6z + 4z - 8)
(4z(3z + 4) + 3(3z + 4))/(3z(z - 2) + 4(z - 2))
((4z + 3)(3z + 4))/((3z + 4)(z - 2))
(4z + 3)/(z - 2)
Answer:
x = 7
angle A = 7(7) + 4 = 49 + 4 = 53°
angle B = 4(7) + 9 = 28 + 9 = 37°
Step-by-step explanation:
m ∠A + m ∠B = 90° Complementary angles sum = 90°
7x + 4 + 4x + 9 = 90
11x + 13 = 90
11x = 77
x = 7
angle A = 7(7) + 4 = 49 + 4 = 53°
angle B = 4(7) + 9 = 28 + 9 = 37°
Check = angle A + angle B = 90° checked
