Answer:

Mean= 31

Step-by-step explanation:

To find the mean you need to add all the number together and then divide by how many ever numbers there are.

In this case

25 + 25 + 30 + 35 + 40=155

There are 5 numbers so you would divide by 5

155/5

=31

x= -13 , y=11

Step-by-step explanation:

Using elimination method, make the x variable equal to eliminate the variable

-3x - y = -28

2x+ 3y=7

2(-3x-y =28)

3(2x+3y=7)

-6x - 2y =56

6x +9y=21

Apply addition

7y = 77

y=77/7 = 11

Use the value of y=11 in

2x+ 3y=7

2x +3(11) =7

2x +33 =7

2x=7-33

2x= -26

x= -26/2 = -13

The area of a rectangle is 5/6 sq foot. The width is 2/3 foot. The length of the rectangle is how many feet

max2010maxim [7]

Answer:

The answer is

$\frac{5}{4} \\$

Step-by-step explanation:

Area of a rectangle = length × width

Since we are finding the length

<h3> $length = \frac{area}{width} \\$ </h3>

From the question

area = 5/6 sq. feet

width = 2/3 foot

Substitute the values into the above formula and solve for the length

The length is

$length = \frac{5}{6} \div \frac{2}{3} \\ = \frac{5}{6} \times \frac{3}{2} \\ = \frac{5}{2} \times \frac{1}{2} \\ = \frac{5}{4}$

We have the final answer as

$\frac{5}{4} \\$

Hope this helps you
