Same side interior angles are supplementary, which means together they add up to 180 degrees.
In order to find the value of angle m, subtract 180 from the supplement.
180 - 78 = 102
The value of m is 102 degrees
Answer: when the equations are equal, that is when x = 1 or x = 2
Step-by-step explanation:
The dog will receive the ball , when both equations intercept , that is , when both equations are equal. This implies :
- x + 2 = 2x
- x - 2x + 2 = 0
x(x-1) - 2 (x - 1 ) = 0
(x - 1 ) ( x - 2 ) =0
Therefore , x = 1 or x = 2
Answer:
Step-by-step explanation:
9) 24=6(-x-3)
24=-6x-18
42=-6x
x=-7
10) 75=3(-6n-5)
75=-18n-15
90=-18n
n=-5
11) -3(1+6r)=14-r
-3-18r=14-r
17=-17r
r=-1
12) 6(6v+6)-5=1+6v
36v+36-5=1+6v
36v+31=1+6v
30=-30v
v=-1
13) -4k+2(5k-6)=-3k-39
-4k+10k-12=-3k-39
6k-12=-3k-39
9k=-27
k=-3
14) -16+5n=-7(-6+8n)+3
-16+5n=42-56n+3
-16+5n=45-56n
61=-61n
n=-1
