Answer:

see below

Step-by-step explanation:

Let r = number of rides

total amount of money spent has to be less than or equal to 50

costs are admission and food and rides

rides cost 1.50 each

50≥ admission + food + rides

50 ≥ 15 +10 + 1.50r

Combine like terms

50 ≥25 + 1.50 r

Subtract 25 from each side

50-25 ≥25-25 + 1.50 r

25 ≥ 1.50 r

Divide by 1.5 on each side

25/1.5 ≥ 1.5r/1.5

50/3 ≥ r

Changing this to a mixed number

16 2/3 ≥r

We can only take a whole number of rides

r = 16

Beverly has not spent all of her 50 dollars since there was a fraction for the rides

cost = 15 +10 + 1.50r

15+10 + 1.5*16

25+24

She has 1 dollar left

Answer to question 1

We want to simplify

$\frac{\frac{4x}{5+x}}{\frac{6x}{x+2}}$

Let us change the middle bar to a normal division sign by rewriting the expression to obtain,

$\frac{4x}{5+x} \div \frac{6x}{x+2}$

We now multiply the first fraction by the reciprocal of the second fraction to get,

$\frac{4x}{5+x} \times \frac{x+2}{6x}$

We cancel out common factors to obtain,

$\frac{2}{5+x} \times \frac{x+2}{3}$

We multiply out to obtain,

$\frac{2(x+2)}{3(x-5)}$

ANSWER TO QUESTION 2

We want to simplify,

$\frac{\frac{x^2+4x+3}{2x-1}}{\frac{x^2+x}{2x^2-3x+1}}$

Let us change the middle bar to a normal division sign by rewriting the expression to obtain,

$\frac{x^2+4x+3}{2x-1}\div \frac{x^2+x}{2x^2-3x+1}$

We now multiply the first fraction by the reciprocal of the second fraction to get,

$\frac{x^2+4x+3}{2x-1}\times \frac{2x^2-3x+1}{x^2+x}$

We now factor to obtain,

$\frac{(x+1)(x+3)}{2x-1}\times \frac{(x-1)(2x-1)}{x(x+1)}$

We now cancel out common factors to obtain,

$\frac{(x+3)}{1}\times \frac{(x-1)}{x}$

We now multiply out to get,

$\frac{(x-1)(x+3)}{x}$

ANSWER TO QUESTION 3

We want to solve the equation,

$\frac{1}{x-1}+\frac{2}{x}=\frac{x}{x-1}$

We need to multiply through by least common multiple of the denominators which is ,

$x(x-1)$

$x(x-1) \times \frac{1}{x-1}+x(x-1) \times \frac{2}{x}=x(x-1) \times \frac{x}{x-1}$

$x+2(x-1)=x(x)$

$x+2x-2=x^2$

$3x-2=x^2$

$x^2-3x+2=0$

$(x-1)(x-2)=0$

$x=1,x=2$

But $x=1$ does not satisfy the equation. It will result in division by zero which is undefined. This is an extraneous solution.

Therefore $x=2$ is the only solution.

The correct answer is D.

The diameter of a circle of 255 π is:

melisa1 [442]

Hello from MrBillDoesMath!

Answer: 30

Discussion:

The area of a circle of radius R is given by the formula

Pi * R^2

We are given that the area is 225 Pi (Not 255 Pi as stated by the author)

Pi * R^2 = 225 * Pi

Divide both sides by Pi :

R^2 = 225 ---> R = 15

The diameter is twice the radius so the diameter = 30.
