6 1/4 = 25/4
(25/4)*3 = 75/4
(72+3)/4 = 72/4 + 3/4 = 18 3/4 miles per hour
The pattern is adding 11 each time. So the next answer would be 40, then 51, then 62, and so on.
Answer:
1st and 3rd choices
Step-by-step explanation:
1st:
The graph follows the y=mx+b pattern, which if fits will always be a straight line.
This expression will be used throughout to explain answers.
3rd:
The y-intercept, or b, is -2. In the y-intercept, the x value is 0, so a point in the line is (0, -2).
The rest:
The 2nd is wrong because the y-intercept is -2. The line is two units below the origin when the x value is zero.
The 4th is wrong, because the slope, m, is 1/3, which is less than 3.
The 5th is wrong, because as explained in the 3rd choice, the y-intercept is -2, not 2.
Answer:
x = 43 degrees; 2x = 86 degrees; x+ 8 = 51
Step-by-step explanation:
x + 2x + x + 8 = 180
4x + 8 = 180
- 8 -8
4x = 172 (divide both sides by 4)
x = 43
