For this case we have an equation of the form:

Where,
h0: initial height
v0: initial speed
a: acceleration
Substituting values we have:

Rewriting we have:

Answer:
Answer = B = 376 degrees - 3x
124 - 78 = 46.....Harrison used 46 more blocks then Greyson
Answer:
Bella will pass Ajjan after 4h and they will have travelled 260 miles.
Step-by-step explanation:
In order to calculate the number of hours, "x", that it'll take for Bella to pass Aljan, we need to find the value of "x" that makes both equations equal. Therefore,

In order to calculate the distance they traveled, we must use this value for "x" in any of the equations, as done below:

Bella will pass Ajjan after 4h and they will have travelled 260 miles.
Answer: x=18
im assuming that this is a right angle
so if it is then that means the total of the angle should be 90 degrees. so 2x+3x should be equal to 90. Just combine like terms to get that 5x=90 and then isolate the variable (divide by 5 on both sides) so x ends up equaling 18.
so x=18
