(HELP ASAP PLEASE!!)
natta225 [31]
<h2>Hello!</h2>

The answer is:

It takes Ella 3 seconds to do a push-up and 3 seconds to do a sit up.

<h2>Why?</h2>

To find how many seconds Ella took to do a push-up and a sit-up we must write two equations using the given information.

Let be "x" the time needed to push-ups and "y" be the time needed to do sit-ups.

So, writing the equations we have:

First equation,

If she can do 13 push-ups and 7 sit-ups in 60 seconds, we have:

13x+7y=60

Second equation,

If she can do 13 push-ups and 19 sit-ups in 96 seconds, we have:

13x+19y=96

Now, creating a system of equations, and using the reduction method to solve it, we have:

\left \{ {{13x+7y=60} \atop {13x+19y=96}} \right.

Multiplying the first equation by -1, we have:

\left \{ {{-13x-7y=-60} \atop {13x+19y=96}} \right.

\left \{ {{-13x-7y=-60} \atop {13x+19y=96}} \right\\\\12y=36\\\\y=\frac{36}{12}=3

Then, substituting "y" into the first equation, we have:

13x+7y=60

13x+7(3)=60

13x+21=60

13x=60-21=39

x=\frac{39}{13}=3

Hence, we have that It takes Ella 3 seconds to do a push-up and 3 seconds to do a sit up.

Have a nice day!

The square below represents one whole.
zaharov [31]

Answer:

6 percent

Step-by-step explanation:

6/100 is shaded. This is the same thing as 0.06. Once I move the decimal two places to the right, I get 6. (I move the decimal place because percents are out of 100, so two decimal places.) This means 6 percent.
