Answer → C) 121°
Step-by-step explanation:
» Let the wanted angle be x
<span>2h + 4 = m (twice the value of Helena's age plus 4 will equal Mark's age)
3j - 6 = g (three time John's age minus 6 will equal Glenn's age)
3.35s + .80b = 11.75</span>
Answer:
m = 30, b = 20
Step-by-step explanation:
1. The equation is written in slope-intercept form, so it follows the following equation: y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = slope.
2. As you can see, 30 is the value that took the place of m, and 20 is the value that took the place of b.
Therefore, m is 30 and b is 20.
7(3x/1)=-1
7(3x)=-1
21x=-1
21x/21=-1/21
X=-1/21
Answer: -1/21
A.
from the question,
the total speed for the pedestrian is
40km and the total time is 10hr
substitute them in the formula, we get
speed = 4km/hr
B. 10hrs - 6hrs = 4hours
C. BC is deacceleration = -dv/dt
CD is constant acceleration = dt = 0
