2a - 15 = -1<br><br> Explain how you got the answer please
Kisachek [45]
You have to isolate the a. Add fifteen to both sides of the equation, so it’s

2a=15-1

Then subtract 15 and 1, so then the quantity is 14

2a=14

Then divide 2 by both sides, and the answer is

a=7

A toy rocket is lunch vertically upward from ground level in into velocity of one 28 ft./s how long will it take for the rocket
pentagon [3]

Answer:

1.14 s

Step-by-step explanation:

Time, t=\frac {d}{s}

Here, d is the distance and s is the speed/velocity

Since we're given the velocity, s as 28 ft/s and the distance between the position of the rocket and ground as 32 ft then

t=\frac {32}{28}=1.142857143\approx 1.14 s

Therefore, it needs 1.14 seconds
