U take it step by step and it also depends on what kind of problem
Answer:
a) t=98
b) b=32
Step-by-step explanation:
a) 4t/7 -20=36r
r=1
4t/7-20=36
=36
4t-140=252
4y=392
t=98
b) 2k/5=b/2-12
k=10
20/5=b/2-12
4=
8=b-24
b=32

Step-by-step explanation:
When the object reaches the ground, the height is zero, so:
0 = 144 - 16t^2
then you just solve for t, so subtract the 144 over
-144 = -16t^2
then divide by the -16
9 = t^2
then take the square root of both sides
3 = t
therefore, it will take three seconds for the object to reach the ground.
