5x-2y = -10
Multiply by 6
= 30x -12y=-60
3x+6y = 66
Multiply by 2
= 6x+12y = 132
So
30x-12y=-60
6x+12y=132
Add those variables
36x= 72
X= 2
This would help
Answer:
c) 500
Step-by-step explanation:
3% = 0.03
multiply the decimal from of 3% by 500:
500 x 0.03
solve:
500 x 0.03 = 15
The answer is C (20) because 3 • x (which is 20) will equal to 60
I hope this helps :)
Since kites have two distinct pairs of consecutive, congruent sides their diagonals are perpendicular and one diagonal
bisects the other.
Since perpendicular lines intersect at 90° every triangle in a kite is a right triangle. Since it is given that angle DEF is 72° and we know triangles equal 180°
72+90=162
180-162 =18
so angle EFD is 18° and because angle EFD is a bisected part of angle EFG - 18x2=36
so angle EFG is 36°
