Multiply the equation (x-2y=10) by -1
-x+2y=-10
x+3y=5
The x’s cancel out
2y=-10
3y=5
Combine
5y=-5
Divide both sides by 5
y=-1
Plug in y to either original equation
x-2(-1)=10
x+2=10
Subtract 2 from both sides
x=8, y=-1
Midpoint= in the middle
Midpoint is D
Answer:
165 ft^2
Step-by-step explanation:
We need to break the figure into 2 parts
We have the square at the bottom right
The square is 5 by 5
A = 5*5 = 25
The rectangle is then 20 by (12-5) =7
The area of the rectangle is
A = 20 *7 = 140
Add the areas together
140+ 25
165 ft^2

Answer:
Step-by-step explanation:
The circumference of the circle is 6π inches
The length of the arc is (20/360)×6π = 1.04 inches
(The complete circumference would cover 360°. Angle ALB is 20°)
