Answer:
x =-5 and y = -6
Step-by-step explanation:
In order to get the answer, I used the elimination/addition method
8y-9x= -3 <— I decided to eliminate the y
5y-8x= 10 <— I decided to eliminate the y
5(8y-9x = -3) <— switch up the number of y from the bottom to multiply
-8(5y-8x= 10) <— switch up the number of y from the top to multiply, but have a negative sign to it
So...our new equation will be....
40y - 45x = -15
+ -40y + 64x = -80
________________________
19x = -95
x = -5
8y-9x= -3
8y-9(-5) = -3
8y+45 = -3
- 45 = - 45
8y = -48
y = -6

Answer:
<em>m∠A = 143° </em>
Step-by-step explanation:
∠A ≅ ∠B (corresponding angles)
(7x)° + 24° = (3x)° + 92°
7x + 24 = 3x + 92
7x - 3x = 92 - 24
4x = 68
x = 17
<em>m∠A </em>= [7(17) + 24]° <em>= 143°</em>

Answer:

Step-by-step explanation:
Area of compound shapes = Area of shape A + Area of shape B
Area of this shape = (L x B) + (L x B)
= (5 x 3) + (6 x 2)
= 15 + 12
=
