GarryVolchara [31]
For this case we have the following expression:
 414x - 812y - 414x
 Rewriting we have:
 414x - 414x - 812y
 We group similar terms:
 (414x - 414x) - 812y
 Adding we have:
 0 - 812y
 - 812y

Mr. Hamilton decorates his U.S. History classroom by putting up pictures of the presidents. The wall is 9.75 feet long. In the c
Archy [21]

Answer:

8 pictures

Step-by-step explanation:

Given

Window = 5\frac{3}{4}ft

Wall = 9.75ft

Pictures = 6\ inches

Required

Determine the number of pictures

First, we need to calculate the length of the available space

This is calculated by subtracting the width of the window from the width of the wall.

Space = Wall - Window

Space = 9.75 - 5\frac{3}{4}

Convert fraction to decimal

Space = 9.75 - 5.75

Space = 4ft

Since, the pictures are placed side by side.

This means that, there's no empty space between them.

Number of pictures is:

Number = \frac{Space}{Pictures}

Number = \frac{4\ ft}{6\ in}

Convert feet to inches

Number = \frac{4 * 12\ in}{6\ in}

Number = \frac{48\ in}{6\ in}

Number = \frac{48}{6}

Number = 8

<em>Hence, 8 pictures can fit the wall</em>

Eric plans to rent a car for a day from Easy Car Rental. He has a coupon for 25% off the daily base rate of $40. He will also ha
Volgvan
In this situation, there are 2 separate terms (parts of the story).  The first part is the information about the coupon that applies to the daily rate of $40.  You will represent this as 0.75 (for the 75% that you will be paying) x 40.  (The other part of this story is that you are paying $0.15 per mile which is represented as 0.15m.  You need to put these together to get 0.75(40) + 0.15m.  The 0.25 times 40 can be simplified to say 30, so write it as $30 + $0.15m.
