Ella swims four times a week at her club's pool. She swims the same number of laps on Monday, Wednesday, and Friday, and 15 laps on Saturday. She swims a total of 51 laps each week. Write an equation for the problem.

Answer:

$671.25

Step-by-step explanation:

To get the amount by which the stock have reduced after 2 years, we will use the interest formula;

Interest = Principal * rate * time/100

Interest = 750*5 1/4 * 2/100

Interest = 750*21*2/400

Interest = $78.75

This means that the value of the stock has reduced by $78.75 after 2 years;

Amount that the stock worth now = $750 - $78.75

Amount that the stock worth now = $671.25

Answer:

72 lemons

Step-by-step explanation:

Carrie uses 6 lemons to make 24 fluid ounces of lemonade. Carrie is planning a big party and needs to make 288 fluid ounces of lemonade. How many lemons will she need to use to keep the recipe proportional?

Hence:.

24 fluid ounces = 6 lemons

288 fluid ounces = x lemons

24 x = 288 × 6

x = 288 × 6/24

x = 72 lemons

Answer:

There are 280 dimes

Step-by-step explanation:

A nickel is worth 5 cents while a dime is worth 10 cents

Let n be number of nickel

d the number of dimes

n + d = 39

Secondly

$39 is same as 3900 cents

So we have;

10d + 5n = 3900

From first equation;

n = 500-d

Put this in second equation;

10d + 5(500-d) = 3900

10d + 2500-5d = 3900

5d = 3900-2500

5d = 1400

d = 1400/5

d = 280

Answer:

No solutions

Step-by-step explanation:

So putting that into an equation it equals

2k+8=(4k+14)÷2

Move the 2 to the other side.

2∙2k+8=4k+14

Simplify.

4k+8=4k+14

It doesn't make sense so No Solutions

Answer:

[tex]6.7-\left(-2.5\right)=9.2[/tex]

Step-by-step explanation:

Given the expression

[tex]6.7-\left(-2.5\right)[/tex]

Solving the expression to get the equivalent function

[tex]6.7-\left(-2.5\right)[/tex]

[tex]\mathrm{Apply\:rule}\:-\left(-a\right)=a[/tex]

[tex]=6.7+2.5[/tex]

[tex]\mathrm{Add\:the\:numbers:}\:6.7+2.5=9.2[/tex]

[tex]=9.2[/tex]

Thus,

Answer:

Not Linear.

Step-by-step explanation:

Answer:

5/4 slope

-7 y intercept.

Step-by-step explanation:

The slope is the number in front of the x. The number in front of the x is 5/4. The slope is 5/4

1. The y intercept is whatever is behind the x or 0 if there is no number following the x.  

2. The y intercept is also characterized by being on the same side of the equation as the x.

3. Finally it has no x in it.

In this case the y intercept is -7

Examples

y + 2 = x    2 is not the y intercept. subtract 2 from both sides. y = x - 2. Therefore -2 is the y intercept.

2y = 4x + 6                4 is not the slope. You have to divide by y = 2x+3. So 2 is the slope and 0,3 is the y intercept.

Multiply amount sold by commission rate:

4500 x 0.13 = 585

She made $585 last week.

Multiply amount made in 1 week by 52 weeks ( 1 year = 52 weeks)

585 x 52 = 30,420

She made $30,420 in 2011

Answer:

J.)

Step-by-step explanation:

if you make there width to their length a ratio - like for the top you would do 8/2 - then the bottom is different. They all simplify to 4/1 except the bottom.

12/3 = 4/1

2/.5 = 4/1

10/2.5 = 4/1

10/4 = 5/2

Answer:

96 pizzas

Step-by-step explanation:

First, we have to determine how many pizza he can make in one minute = 8/15 = 0.533

Convert 3 hours to minutes = 3 x 60 = 180 minutes

The number of pizzas he would make in 3 hours = 180 x 0.533 = 96 pizzas

Answer:

25

Step-by-step explanation:

5+7 is 12, 60 divided by 12 is 5.   5x5 is 25
