The answer is 16.  To solve this problem, it will look like this:
5 n + n = 24
So, 6(4) = 24. n=4
With this equation, you can see that 4 kids walk to school and 20 take the bus. Then you need to do 20 - 4 = 16. So 16 more kids take the bus than walk to school. 

Another way to look at it...
We know there are 5 times as many bus kids as there are walkers. 
walkers - n
bus kids - n+n+n+n+n
6n = 24 (the total number of students), which can translate to 6 x n = 24. We know that 6x4=24, so n=4. The number of kids that walk is 4. The number of kids on the bus is 20. So subtract the bus kids from the walking kids, and that leaves us the answer. 16 more students ride the bus than those who walk. I hope that helped.

Henrietta is planting a new flower garden she must have yellow and red rose bushes let X represent the number of yellow rose bus
salantis [7]

Answer:

x \geq 4y

7.50x+4.75y\leq 125

x > 0

y > 0

Step-by-step explanation:

Let

x -----> the number of yellow rose bushes

y -----> the number of red rose bushes

we know that

At least means "greater than or equal to"

x \geq 4y ----> inequality A

7.50x+4.75y\leq 125 -----> inequality B

additionally

The number of roses cannot be a negative number

so

x > 0 ----> inequality C

y > 0 ----> inequality D

therefore

The restraints are

x \geq 4y

7.50x+4.75y\leq 125

x > 0

y > 0

You are swimming each 25 yard length of a swimming pool 3 seconds faster than your personal best. What integer represents your c
stealth61 [152]

To solve this problem you must apply the proccedure shown below:

1- The problem says that you are swimming each 25 yard length 3 seconds faster than your personal best and you have to calculate the change in time (which you can call x) of your personal best after 200 yards.

2- To calculate this, you must multiply 200 yards by 3 seconds and divide by 25 yards, as following:

x=\frac{(200yd)(3s)}{25 yd}=24s

Therefore, the answer is: 24 seconds.

The length of a rectangle is the sum of the width and one. The area direct angle 72 units. What’s the length, in units, of the r
insens350 [35]

Answer:

The length of the rectangle is of 9 units.

Step-by-step explanation:

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

ax^{2} + bx + c, a\neq0.

This polynomial has roots x_{1}, x_{2} such that ax^{2} + bx + c = a(x - x_{1})*(x - x_{2}), given by the following formulas:

x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}

x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}

\bigtriangleup = b^{2} - 4ac

Area of a rectangle:

A rectangle has width w and length l. The area is the multiplication of these measures, that is:

A = wl

The length of a rectangle is the sum of the width and one.

This means that l = w+1, or w = l - 1

The area direct angle 72 units. What’s the length, in units, of the rectangle

We want to find the length. So

wl = 72

(l-1)l = 72

l^2 - l - 72 = 0

Quadratic equation with a = 1, b = -1, c = -72. So

\bigtriangleup = (-1)^{2} - 4(1)(-72) = 289

l_{1} = \frac{-(-1) + \sqrt{289}}{2*(1)} = 9

l_{2} = \frac{-(-1) - \sqrt{289}}{2*(1)} = -8

Since the length is a positive measure, the length of the rectangle is of 9 units.
