Answer:
x=18
Step-by-step explanation:
Triangles add up to 180°, so 140+22+x=180 and then you simplify which is 162+x=180, then you subtract 162 on both side, getting x=18
Answer:
8
Step-by-step explanation:
x-3=5
add the 3 to both sides of the equal sign
x-(3+3)=(5+3)
x=8
To answer the question above, determine the velocity of the car at time zero. To do such, determine the increase in velocity every hour (acceleration).
a = (62 - 53) / (6 -3) = 3 km/ h^2
Calculate for the initial velocity (v) by using either of the velocities paired with the corresponding time,
v = 53 km/h - (3 km/h^2) x 3 h = 44 km/h
The equation is <em>y = 44 + 3x</em>. Where x is the time in hours, y is the velocity in km/h.
