X=3x-2.4 because if you substract from one side you have to do it to the other
12,089 is less than 12,098
The first choice is the correct one.
it is 24.75
I used a long division method to find the value of 50
06087
Answer:
C. The slope is 3 and the y-intercept is -3
Answer:
y = 20°
x = 35°
Explanation:
Equation's:
1) 2y + x + 105° = 180°
2) 3x + x + 2y = 180°
Make y subject in equation 2
3x + x + 2y = 180
4x + 2y = 180
2y = 180 - 4x
y = 90 - 2x
Insert this into equation 1
2(90 - 2x) + x + 105° = 180°
180 - 4x + x + 105 = 180
-3x = -105
x = 35°
Find value of y
y = 90 - 2x
y = 90 - 2(35)
y = 20°
