Answer:
X=17
Step-by-step explanation:
7x-1+5x-23=180
12x-24=180
12x=204
x=17
The solutions would be x=8 and x=2
Answer:
Step-by-step explanation:
1*12 + 2*2 + 3*6 = 12 + 4 +18 = $34

Answer:
y = 2x -4
Step-by-step explanation:
The coefficient of x in the given equation is the slope of the line. A perpendicular line will have a slope that is the opposite reciprocal:
-1/(-1/2) = 2
The point-slope form of the equation of a line can be used to find the desired equation:
y -y1 = m(x -x1) . . . . . . line through (x1, y1) with slope m
For (x1, y1) = (2, 0) and m = 2, the equation is ...
y -0 = 2(x -20
y = 2x -4
Answer:
x=55
Step-by-step explanation:
(2x+6)+(x+9)=3x+15
3x+15=180
3x=165
x=55
