The coordinates for the vertices of a patio are (1,5) (6,5) (6,1) and (1,1). Each grid square has a length of 5 feet. Find the p

nadezda [96]

Answer:

The perimeter of the figure is $90\ ft$

Step-by-step explanation:

Let

$A(1,5),B(6,5),C(6,1),D(1,1)$

using a graphing tool

see the attached figure

The perimeter is equal to

$P=AB+BC+CD+AD$

The figure is a rectangle

so

$AB=DC=(6-1)=5*5=25\ ft$

$AD=BC=(5-1)=4*5=20\ ft$

$P=2(25+20)=90\ ft$

I feel so stupid, how do you change a fraction into a mix number???

Vlad [161]

Answer:

Divide the numerator by the denominator. Your answer would be the whole number, and the remainder would be your fraction.

I have also clipped a picture from fractionfun.com to make it more clear.

X - 3= -21 <br>This is so confusing:(

Aneli [31]

Answer:

$\huge\boxed{x=-18}$

Step-by-step explanation:

In order to solve this, we are trying to find the value of $x$ . Basically, $x$ is a placeholder for a number that is unknown. Some number minus 3 is equal to 21.

Our goal is to find $x$ . To do this we want to isolate $x$ on one side of the equation

$x-3=-21$

Let's add 3 to both sides.

$x-3 + 3 = -21+3\\\\-3 + 3 = 0\\\\x = -21+3\\\\x=-18$

Hope this helped!

at shop and shop ,shaquana buys 3 pounds of squash and 2 pounds of eggplants and pays $2.85.then ,evelyn buys 4 pounds of squash

Montano1993 [528]

Each pound of squash cost $0.49 while each pound of eggplant cost $0.69.

Let x represent the cost of each pound of squash and y represent the cost of each pound of eggplant.

3 pounds of squash and 2 pounds of eggplants cost $2.85. Hence:

3x + 2y = 2.85 (1)

4 pounds of squash and 5 pounds of eggplants cost $5.41. Hence:

4x + 5y = 5.41 (2)

Solving equation 1 and 2 simultaneously gives:

x = 0.49, y = 0.69

Each pound of squash cost $0.49 while each pound of eggplant cost $0.69.

An auto shop charges a customer an equal amount for each new tire purchased plus an additional fee for an oil change.

Nitella [24]

The cost per unit of the auto shop function is the slope of the function

87 represents the slope and the cost per tire purchased

The function is given as:

$\mathbf{C(t) = 87t + 32}$

A linear function is represented as:

$\mathbf{C(t) = mt + b}$

Where:

m represents the slope or the unit rate.

So, by comparison:

$\mathbf{m = 87}$

This means that 87 represents the slope and the cost per tire purchased
