7x+12+63=180
8x+12=180
Subtract 12 from both sides
8x= 168
=c=21
10x-40=50
Add 40 to both sides
10x=90
X=9
4x+72+2x-12=180
6x +60 =180
Subtract 60 from both sides
6x=120
X=20
For quadrilaterals inscribed in a circle, the opposite angles must sum up to 180 degrees. Therefore, angle I + angle D should add up to 180
45 + angle D = 180
angle D = 135 degrees.
(Similarly, angles L & W would also add up to 180, and angle L = 81 degrees.)
$56.25, since 25% off can also be written as ÷4, since 25 is a quarter. 75÷4=18.75
75-18.75=56.25. Therefore, the answer is $56.25
Answer:
If the equation is 3x^2+6y^2, when x=0 and y=2.
Then, 3(0)^2+6(2)^2=
So, 0+6(4)= 24
Therefore, the answer is 24.
Step-by-step explanation:
<span>Find the difference between ninety-eight and seventy-eight, then multiply by eleven. Ninety-eight minus seventy-eight is twenty, take this and multiply if by eleven to arrive at an answer of eleven. Following the order of operations the math within the parentheses must be done first, then the multiplication. The answer is two-hundred and twenty.</span>
