Question 5 of 10
Solve the rational equation:
4x/x+5 = x/x+4

Answers

Answer 1

Answer:

[tex] x = 0 [/tex]  or  [tex] x = -\dfrac{11}{3} [/tex]

Step-by-step explanation:

I assume the denominators are x + 5 and x + 4 although that is not what you wrote.

[tex] \dfrac{4x}{x+5} = \dfrac{x}{x+4} [/tex]

[tex] (x + 4)(x + 5)\times \dfrac{4x}{x+5} = (x + 4)(x + 5) \times \dfrac{x}{x+4} [/tex]

[tex] (x + 4)(4x) = (x + 5)(x) [/tex]

[tex] 4x^2 + 16x = x^2 + 5x [/tex]

[tex] 3x^2 + 11x = 0 [/tex]

[tex] x(3x + 11) = 0 [/tex]

[tex] x = 0 [/tex]  or  [tex] 3x + 11 = 0 [/tex]

[tex] x = 0 [/tex]  or  [tex] 3x = -11 [/tex]

[tex] x = 0 [/tex]  or  [tex] x = -\dfrac{11}{3} [/tex]

=50k+5+4+16k

=66k+9 OR 3(22K+3)

(ANSWER)

Answer:

66k + 9

Step-by-step explanation:

The question isn't mentioned, so assuming we need to simplify :

5(10k + 1) + 2(2 + 8k)

Distribute the terms in the parentheses.

5(10k) + 5(1) + 2(2) + 2(8k)50k + 5 + 4 + 16k

Combine like terms.

50k + 16k + 5 + 466k + 9

ebrant spends $76 in a gift shop. This is 80% of the money he planned to
spend in the gift shop. How much money, in dollars, did Mr. Hildebrant plan to
spend in the gift shop?

Answers

Answer:

Mr. Hildebrant planned to spend $95 in the gift shop.

Step-by-step explanation:

We want to find 80% of $? equals $76.

We can write an equation to help us solve for x, the money that Mr. Hildebrant planned to spend in the gift shop.

.80x = 76

Divide both sides of the equation by .80.

x = 95

Mr. Hildebrant planned to spend $95 in the gift shop.

The expression that results in rational number are A+B, A+D, B+D and A+A

What are rational numbers?

Rational number are numbers that include the square root of prime numbers

Given the following parameters

A= √3
B = 2√3C = √25 = 5
D = √16 = 4

We need to determine the operation that will result in a rational number

A + B = √3 + 2√3

A+B = 3√3

A+D = √3 + 4
B + D = 2√3 + 4

A + A = √3 +√3 = 2√3

Hence the expression that results in rational number are A+B, A+D, B+D and A+A

15) A, B, C, D, E and F are towns situated as follows. * A is 30 km east of D * C is 20 km east of E * F is 10 km west of B * D is 10 km south of F * A is 10 km north of C How far would you need to travel to get from B to E?​

Answers

Answer:

Option D: 20km South

Step-by-step explanation:

Lets say A = (0, 0)

Finding B:

A is 30km East of D which makes D = (-30, 0)

D is 10km South of F which makes F = (-30, 10)

F is 10km West of B which makes B = (-20, 10)

Finding E:

A is 10km North of C which makes C = (0, -10)

C is 20km East of E which makes E = (-20, -10)

Finding the answer:

Find distance from B = (-20, 10) to E = (-20, -10)

     1. Cancel equivalent values:

x of B = (-20) and x of E = (-20)

Remove x from equation.

     2. Solve for answer:

B = 10 and E = (-10)

Find the difference: (-10) - 10 = (-20)

Conclusion:

South translates to negative on a graph making the answer 20km South

Two containers designed to hold water are side by side, both in the shape of a
cylinder. Container A has a diameter of 12 feet and a height of 16 feet. Container B
has a diameter of 16 feet and a height of 13 feet. Container A is full of water and the
water is pumped into Container B until Container A is empty.
After the pumping is complete, what is the volume of water in Container B, to the
nearest tenth of a cubic foot?

Answers

Volume = pi x radius^2 x height
Cyl A = pi x 6^2 x 16
= 1809.6 cu ft
Cyl B = pi x 8^2 x 13
=2613.8 cu ft

You pumped 1809.6 from A to B so volume of water in B is 1809.6 cu ft

Optimize the equation P = 3x + y using the constraints
x ≥ 0, x ≤ 4, y ≥-1 and y ≤ 5.
What is the maximum?

Answers

Answer:

P = 17

Step-by-step explanation:

let's separate this into x and y components

x component: 3x

as x increases, so does the x component. e.g. 0 * 3 = 0, 4 * 3 = 12. therefore, we want x as high as possible

y component: y

as y increases, so does the y component. this is because the y component is literally just y.

therefore, given these two, to maximize P, we want x and y to be as high as possible

in 0 ≤ x ≤ 4, the maximum of x is 4

in -1 ≤ y ≤ 5, the maximum of y is 5

plug these in to get

3(4) + 5 = 17 as our answer

Explanation:

Purchasing the correctly sized BMX bike is based on the height of the rider. In order to fit a customer, the salesman can use the equation b=0.29h+1.35 where b is the size of the BMX bike frame in inches and h is the height of the rider in inches.

Answers

Answer:

  (a) 1 inch of rider ⇒ 0.29 inches of frame

Step-by-step explanation:

The "slope" in the equation is the coefficient of the independent variable. Here, that variable is "h", and its coefficient is 0.29. That is, the height of the rider is multiplied by 0.29 (and a constant is added) in order to find the height of the frame.

__

The meaning of the value 0.29 is that a 1 inch increase in the rider's height should result in a 0.29 inch increase in the height of the frame of the bike.

The question asks for an explanation of the slope, not its function in the equation. That is why we have chosen the first answer.

Answer: inch of rider ⇒ 0.29 inches of frame

Step-by-step explanation:

Use the digits 1-9 at lost one time each to make the equation true and give the solution.
