X+y=-1
3x-y=21
add them equations
x+y=-1
<u>3x-y=21 +</u>
4x+0y=20
4x=20
divide by 4
x=5
x+y=-1
5+y=-1
minus 5 both sides
y=-6
(x,y)
(5,-6)
D is answer
Answer:
x=3
Step-by-step explanation:
6x - 2 = x + 13
subtract 1x from both sides
5x - 2 = 13
isolate the 5x by adding 2 to both sides
5x = 15
finnaly devide both by 5
x = 3
From the order you gave me in the question the answer is equation number
4 1 3 2 6 5
Those are the equation numbers in ascending order based on their radius lengths
Answer:
Supplementary
Step-by-step explanation:
The two angles are completely different from each other and if you combine them together it'll form a straight line making it 180 degrees
