Answer:
18
Step-by-step explanation:
13 + (⅔)t = 16 + (½)t
(⅔ - ½)t = 3
t/6 = 3
t = 18
12c - 53 = 91
First add 53 to each side. This cancels it out on the left (-53 + 53 = 0)
12c = 91 + 53
12c = 144
Now divide by 12 on each side. This cancels the 12 on the left (12/12 = 1)
c = 144/12
c = 12
Answer: 31°
Step-by-step explanation:
180° - 149° = 31°
The slope of the lines is -0.75 and 0.75 respectively. This shows that the slope of one of the<u> line is negative of the other.</u>
<h3>Slope of a line</h3>
The slope of a line is the rate of change of the y-axis of the coordinate to x-axis. The formula for calculating the slope of a line is expressed as;
Slope = y2-y1/x2-x1
Given the following coordinate point (−8, 9) to (−4, 6), the slope is calculated as;
Slope = 6-9/-4+8
Slope = -3/4
For the coordinate points (-4, 6) and (2, 1.5), the slope is calculate;
Slope = 1.5-6/2+4
Slope = -4.5/6
Slope = 0.75
Hence the slope of the coordinate point is 0.75.
Hence the slope of the lines is -0.75 and 0.75 respectively. This shows that the slope of one of the<u> line is negative of the other.</u>

Answer:
the answ
Step-by-step explanation:
It would be 18x-3y=21 then it would be -3y=21-18x than it would be y=21/-3-18x/-3 then the answer would be y=-7+6x than the answer would be y=6x-7
