Answer:
Equation for the problem
3x + 15 = 51 laps
Hence
She swims on
Monday: 12 laps
Wednesday : 12 laps
Friday = 12 laps
Step-by-step explanation:
Ella swims four times a week at her club's pool.
We are told that:
She swims the same number of laps on Monday, Wednesday, and Friday.
Hence, the number rod times that she swims on Monday, Wednesday and Friday is represented by x
Also, she swims 15 laps on Saturday. She swims a total of 51 laps each week. Equation for the problem
= x + x + x + 15 = 51 laps
3x + 15 = 51 laps
Hence
3x = 51 - 15
3x = 36
x = 36/3
x = 12 laps
Therefore, She swims on:
Monday: 12 laps
Wednesday : 12 laps
Friday = 12 laps

A coin collection consists of dimes and nickels. If there are a total of 500 coins valued
at $39. how many dimes are there?
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
Carrie usa 6 limones para hacer 24 onzas líquidas de limonada. Carrie está planeando una gran fiesta y necesita hacer 288 onzas líquidas de limonada. ¿Cuántos limones necesitará usar para mantener la receta proporcional?
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

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

Find the slope and the y-intercept of the graph of the linear equation y=5/4x-7. The slope is ?, and the y-intercept is ?.
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.

What expressions are equivalent to 6.7 - (-2.5)
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,

Nadia is a stockbroker. She earns 13% commission each week. Last week, she sold $4,500 worth of stocks. How much did she make last week in commission? If she averages that same amount each week, how much did she make in commission in 2011?
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
Twice a number k plus 8 equals one-half times the quantity of four times a number k plus fourteen ?
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

Two years ago, Jose bought $750 worth of stock in a cell phone company. Since then the value of his stock has been DECREASING at an average rate of 5 1/4 % per year. How much is the stock worth now?
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

Allan can make 8 pizzas in 15 minutes at the pizza restaurant where he works. 28. __________ If the number of pizzas varies directly with minutes, how many pizzas can Allan make in 3 hours?
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
