A rectangular doubles tennis court is (8x - 2) ft long and (4x - 4) ft wide. Which expression represents the perimeter of the tennis court?
A (12x - 6) ft
B. (12x + 6) ft
C (24x - 12) ft
D. (24x + 12) ft
If you can please show the steps​

Answers

Answer 1

Answer:

C

Step-by-step explanation:

Remark

The easiest way to do this is to add the two givens together and then multiply by two. Why 2?  Because the formula is P = 2(L + W)

Givens

L = 8x - 2

W = 4x - 4

Solution

P = 2*(8x - 2 + 4x - 4)

P = 2*(12x - 6)

P = 24x - 12

Find two mixed numbers so that the sum is seven wholes and two eights and the difference is two wholes and four eigths

Answers

Answer:

Step-by-step explanation:

x + y = 7 + 2/8 = 58/8

x - y = 2 + 4/8 = 20/8

Add the equations together

2x = 78/8

x = 39/8

y = x - 20/8 = 19/8

x = 39/8 = 4⅞

y = 19/8 = 2⅜

Elena bowls two games on Saturday. Her score in the second game is 30 more than ¾ of her score the first game. Elena's total score for the two games is 478. Write and solve an equation to demonstrate the points scored in her second game.

Answers

Answer:

222 = score in 2nd game

Step-by-step explanation:

Let x = score in 1st game

3/4(x) + 30 = score in 2nd game

x + 3/4(x) + 30 = 478         Multiply thru by 4 to eliminate the fraction

4x + 3x + 120 = 1912

7x + 120 = 1912

7x = 1792

x = 256

3/4(x) + 30 = 3/4(256) + 30

= 192 + 30

222 = score in 2nd game

Check:  222 + 256 = 478

You buy a new video game for $60.
The sales tax is 8%.

What is the total cost for the game including sales tax?

Answers

Answer:

$64.8

Step-by-step explanation:

To determine the tax, you want to make the percent into a decimal by moving the decimal point over two times the the left, which means 8% would be 0.08. Then, multiply the new decimal by the price. 60 times 0.08 is 4.8. Now, add the tax to the original price. 60+4.8=64.8, so therefore the total cost is $64.8

The bowling alley charges a flat feeof $45 for a private party and $5.50 per person for shoe rentals and unlimited bowling. Write an inequality that represents the total cost of Ben’s birthday for p people given his budget.

Answers

Answer:

45+5.50p=80

Step-by-step explanation:

45 is the flat fee and 5.50 is the shoe rental and unlimited bowling, so p is next to that because its 5.50 PER person so if ben had 2 people it would be 5.50 times 2 plus 45. But remember it cannot be over 80. please mark brainliest

There is a line that includes the point (4,8) and has a slope of 4 What is its equation in slope- intercept form

Answers

Answer:

y=4x-8

Step-by-step explanation:

1) The slope-intercept form of an equation looks like this:

y=mx+b

The m stands for the slope and the b stands for the y-intercept. We need two points on the line to write out this equation.

2)We have the slope you entered in, so we'll plug that in first:

y=4x+b

3) Now, let's plug in that point you entered in to solve for b:

​ y=4x+b

8=4(4)+b

8=16+b

8-(16)=b

-8=b

   

4) Now that we have both our slope, m, and our y-intercept, b, values, we can plug them in to get our equation:

y=mx+b

y=4x-8
