Answer:
Step-by-step explanation:
2x+3x+5x = 180°
x = 18°
Angles: 36°, 54°, 90°
Well the first part is 27 but the second part is adding 60 to 21 which is 81. dont forget that!
(B) x = 40
Step-by-step explanation:
4x + 20 = 180
4x = 160
x = 40
Answer:
Step-by-step explanation:
the difference is 56 because if you add and divide them by 3 and -2 you will get 56
Answer:
Graphing
Step-by-step explanation:
1) You can graph this equation by using y=mx+b. You can replace that equation with y=3x-1.
M=3
X=x
B=-1
On a graph you would down 1 since it's negative and make a point. Then you would put a 1 under the 3 to make it a fraction. 3/1. Then you would divide 1 by 3 (1 ÷ 3). Then you would go to the right 0.33 because it's positive, and the up 1. Then you would make a second point.
This would only give you one line which wouldn't give you an intersection.
