Answer:
x=12 ; y=8
Step-by-step explanation:
8x+13=11x-23(2 opposite side of a parallelogram is equal)
move the x terms to the left side.
8x-11x=-23-13
-3x=-36
3x=36
x=12
2y+12=4y-4(2 opposite side of a parallelogram is equal)
move the y terms to the left side
2y-4y=-4-12
-2y=-16
2y=16
y=8
It is 4 square cm hopefully that help with part of the question
Answer:
Shown Below
Step-by-step explanation:
Alright so first off we are going to use the little 67 on that corner. We know that it's a supplementary angle, and supplementary angles add up to 180.
180 - 67 = 113.
Inside angles of a triangle all add up to 180. Using that we can create the equation:
(x + 27) + x + 113 = 180
simplify.
2x + 140 = 180
subtract 140 on both sides.
2x = 40
divide both sides by 2
x = 20
substitute x into the asked equation.
(20 + 27) = 47
47 is your answer.
Answer:
D
Step-by-step explanation:
D says four-tenths and 2 times 2 is 4 and 5 times 2 is 10 so 2/5 is equal to 4/10.
Answer:
15
Step-by-step explanation:
GH = (BC + FE) /2
9x-3 = (19+ 5x+1) /2
2* (9x-3) = 19+ 5x+1
18 x - 6 = 5x + 20
13x = 26
x = 2
GH = 9*2 - 3 = 15
