Answer: It is 46.667 percent decrease

Step-by-step explanation:

To get the answer you subtract the two values first.

15-8=7

Then divide the answer by the original value. 7/15=0.46667

Then multiply the answer by 100

0.46667x100=46.667

And there you have it. Round as necessary.

2x+2y=10 solve for x

irakobra [83]

Isolate the x. Note the equal sign. What you do to one side you do to the other.

Subtract 2y from both sides

2x + 2y (-2y) = 10 (-2y)

2x = 10 - 2y

Isolate the x, divide 2 from both sides and from all terms.

(2x)/2 = (10 - 2y)/2

x = 5 - y

Place the variable in the front

x = -y + 5

x = -y + 5 is your answer

hope this helps

A ball is rolled at a velocity of 12m/sec.after 36 seconds,it comes to a stop what is the acceleration of the ball?

miv72 [106K]

acceleration of ball is $\frac{-1}{3}\,\,m/sec^2$

Step-by-step explanation:

Initial Velocity = 12m/sec

time = 36 s

Final Velocity 0 m/sec (ball comes to stop)

Acceleration= ?

The formula used to find acceleration is:

$Acceleration=\frac{Final\,\,Velocity-Initial\,\,Velocity}{Time}$

Putting values and finding acceleration:

$Acceleration=\frac{Final\,\,Velocity-Initial\,\,Velocity}{Time}$

$Acceleration=\frac{0-12}{36}$

$Acceleration=\frac{-12}{36}$

$Acceleration=\frac{-1}{3}\,\,m/sec^2$

So, acceleration of ball is $\frac{-1}{3}\,\,m/sec^2$
