10x = 4(2x -9)

10x = 8x - 36

x = -18

Ronaldo can kick a soccer ball 35 meters per second which is about 80 mph. He kicked the ball from one end of the field to the o
professor190 [17]

Answer:

t=3.142sec

Step-by-step explanation:

From the question we are told that:

Speed of ball V=35m/s\approx 80 mph

Length of field l=110m

Generally the equation for Time taken t is mathematically given by

 t=m/V

 t=110/35

 t=3.142sec

 t \approx \frac{3.142}{60}

 t \approx 0.05hrs

Therefore it will take the ball to get from one end of the field to the other

t=3.142sec

Two trays contained 12 ice cubes. How many ice cubes are there in 20 trays?
Masja [62]

If 2 trays have 12, and you need to get 20 trays, find out 2 * x = 20.

2 * 10 = 20.

So you need to multiply the problem by 10

10(2 trays = 12 ice cubes)

20 trays = 120 ice cubes.
