Answer:

2 ( 24 ) + 2 a = 215

Step-by-step explanation:

Perimeter of the rectangle is 215 feet, the short sides are 24 feet long and we need to work out the long sides (we will call a long side 'a') so,

24 + 24 + a + a = 215

For this case we have to:

Let "a" be the variable that represents the length of the rectangle and let "b" be the variable that represents the width of the rectangle. Then the perimeter is given by:

P = 2a + 2b

We have as data that:

P = 215 \ feet\\b = 24 \ feet

Then, replacing:

215 = 2a + 2 (24)

Answer:

Option B

Given that,

Michael is leaving a 15% tip for his waitress.

To find,

What percent of the  original price will he pay.

Solution,

Let the original price was 100%.

When he leaves a 15% tip for the waitress, he is really paying 100%+15%=115% of the original price.

115\%=\dfrac{115}{100}\\\\=1.15

or

\dfrac{115}{100}=\dfrac{23}{20}

So, this is the required solution.

Complete the table and show work
Alinara [238K]
So the formula for this is for every inch of width, you multiply by 2 to get the length. 

Here, I made a table for it. 

2×2=4

4×2=8

7×2=14

8×2=16 or 16÷2=8

Explain the effect f (x)+k has on the graph if the exponential function f (x) Be specific and use complete sentences for full cr
Masteriza [31]
The +k part of the function takes the original function and translates it straight up k units. It's as simple as that.  If your function is the line f(x) = 3x, then the function f(x) = 3x + 4 moves that first function up 4 units.
