The third option is the correct answer
Answer:
-40x+20
Step-by-step explanation:
10 times -4x=-40x
10x2=20
Answer:
Step-by-step explanation:
13=3x+4
subtract 4 from both sides
9=3x
divide by 3
x=3
To find a constant velocity, we divide the distance by the time
We have:
Distance = 45 meters ⇒ The ball is kicked half way down the soccer field, so the distance that the ball traveled is 90 ÷ 2 = 45 meters
Time = 3 seconds
We have enough information to work out the velocity
v = s ÷ t
v = 45 ÷ 3
v = 15 m/s
