Answer:

h = 2.5

Step by step explanation:

We have been given an equation 9(u-2)+1.5u=8.25 that models the total miles Michael traveled one afternoon while sledding, where u equals the number of hours walking up a hill and (u – 2) equals the number of hours sledding down the hill.

To find value of u we will solve our equation.

Upon using distributive property we will get,    

9(u-2)+1.5u=8.25

9u-18+1.5u=8.25

Now let us add 18 to both sides of our equation.

9u-18+18+1.5u=8.25+18

9u+1.5u=8.25+18

Now let us combine like terms.

10.5u=26.25

Upon dividing both sides of our equation by 10.5 we will get,

u=\frac{26.25}{10.5}

u=2.5

Therefore, value of u is 2.5.

The length of a rectangular garden is 17 feet longer than its width. If the area of the garden is 234 square feet, what are the
kifflom [539]

Answer:

The garden is 9 feet wide and 26 feet long.

Step-by-step explanation:

L = W+17

area = LW = 234

(W+17)W = 234

W²+17W-234 = 0

Quadratic formula

W = [-17 ± √(17² – 4·1(-234))] / [2·1]

 = [-17 ± √1225] / 2

 = [-17 ± 35] /2

 = -26, 9

-26 is an extraneous solution

W = 9

L = W+17 = 26

The garden is 9 feet wide and 26 feet long.

A museum has a 1/2 ounce piece of a precious metal. When the museum first received the piece, it had a value of $90. Its value h
Alex777 [14]
The current value of the precious metal is $144/oz

-First, you'd want to determine the original value per ounce since that's what the final unit being asked for is.

- Since the original value of the half ounce piece is given, this first step is fairly simple. You just double ninety.

- We now know that the metal was worth $180/oz when the museum first received it.

- We need to determine the current price of the metal now that is has had a twenty percent loss of value.

- My favorite way to factor in 20% is simply to divide by five since it's a lot more simple than finding the ratio of x$/1%

- $180/5=$36

- Thirty-six dollars is the price drop over the course of the museum possessing the precious metal.

- You now take $180-$36=$144
