Answer:

x = 6.

Step-by-step explanation:

2x - 5 = 7

2x = 7 + 5

2x = 12

x = 6

Check your work!

2 * 6 - 5 = 7

12 - 5 = 7

7 = 7

Hope this helps!

Answer:

x=6

Step-by-step explanation:

2x - 5 = 7

Add 5 to each side

2x-5+5 = 7+5

2x= 12

Divide by 2

2x/2 = 12/2

x = 6

Sharon is jumping from an 18-foot diving board with an initial upward velocity of 4 ft/s. when sharon jumps, megan throws a beac
Alinara [238K]

It will take 1.08 seconds for the ball to reach Sharon after she jumps if the upward velocity of the ball is 16 ft/s from a height of 5 feet option third is correct.

<h3>What is the equation of motion?</h3>

It is defined as the equation by which we can find the motion of a physical particle with respect to time. It is the representation of physical entity movement in a mathematical function.

We have:

The height of the Sharon from the diving board = 18 feet

The initial upward velocity of the Sharon = 4 ft/s

The height of the Megan from the ground = 5 feet

The initial upward velocity of the beach ball = 16 ft/s

We know the equation of motion is given by:

\rm h(t) = x + ut+\frac{1}{2} gt^2

Put x = 18 feet and u = 4 ft/s in the above equation, we get:

\rm h(t) = 18 + 4t+\frac{1}{2} \times9.8t^2 ....(1)     [g = 9.8 m/s²]

Put x = 5 feet and u = 16 ft/s in the equation of motion, we get:

\rm h(t) = 5 + 16t+\frac{1}{2} \times9.8t^2  ....(2)

Equate the equation (1) and equation (2), we get

\rm  18 + 4t+\frac{1}{2} \times9.8t^2= 5 + 16t+\frac{1}{2} \times9.8t^2\\

18 + 4t = 5 + 16t

12t = 13

t = 1.08 seconds

Thus, it will take 1.08 seconds for the ball to reach Sharon after she jumps if the upward velocity of the ball is 16 ft/s from a height of 5 feet.
