What is the length of a rectangle who’s permitter is P if the width is 6

dolphi86 [110]

Answer:

(P-12)/2 = L

Step-by-step explanation:

1. Start off with an equation in terms of perimeter

P = (2)(6) + (2)(L)

2. Multiply the two and the six

P = 12+ (2)(L)

3. Move the terms around so only "L" is on one side

(P-12)/2 = L

The scale factor of a room for a scale drawing is 2.3. The actual length of a wall in the room is 46 feet and the actual width o

dimaraw [331]

Answer:

There's two ways to solve this.

Step-by-step explanation:

First way:

Let's divide the width and length by 2.3.

46÷2.3=20

69÷2.3=30

20×30

600 ft²

Second Way:

Let's find the area of the actual room.

46×69

3,174 ft²

Let's find the scale drawing squared.

2.3²=5.29

3,174÷5.29

600 ft²

A linear function has the same y-PLEASE PLEASE HELP!!!!intercept as x+2y=10 and it’s graph contains the point (9,7) find the slo

Anastasy [175]

Answer:

I think it is 2/9 or 0.22

Step-by-step explanation:

You know they have the same y intercept, so first you should find the y intercept of the givern equation.

x+2y = 10

2y = -x + 10 [subtract x]

y = -.5x + 5 [divide by 2]

Now you have the equation in graph form, and know the y intercept is 5.

If the unknown function has the same y intercept, you know it contains the point (0,5), and it is given that it includes the point (9,7)

now that you have two points, you can use slope formula.

(y2 - y1)/(x2-x1)

(change in y)/(change in x)

so,

(7-5)/(9-0) = 2/9 = 0.2

someone please correct me if i'm wrong:)

Darina [25.2K]

Answer:

0.4r

Step-by-step explanation:

40% of the price of r dollars

To translate into an expression, we outline te keywords

Percentage of price = 40%

The price in question = $r

Hence, the expression will calculate, 40% of the price

Hence, we'll have :
