Answer:

782 in

Step-by-step explanation:

To find the length of fence, we have to find the perimeter first.

Given

Length = l = 25 feet 8 in

Width = w = 8 feet 8 in

Opening = o =3 feet 6 in

So,

we have to convert the lengths into same unit first

So,

l = (25*12)+8 = 308 in

w = ( 8*12) +8 = 104 in

O = (12*3) + 6 = 42 in

Perimeter = 2(l+w)

= 2(308+104)

=2(412)

=824

As the opening does not need fencing

Total fence = P - o

= 824 - 42

=782 in

or

65 feet 2 in ..

A contractor is setting up new accounts for the local cable company. She earns $75 for each customer account she sets up. Which
Trava [24]

Answer:

B

Step-by-step explanation:

The contractor gets $75 for every single customer she sets up. Okay, so if she sets up 1 customer, she gets $75, if she sets up 2, she gets $150 and so on.

This is a multiplication expression since multiplication is just repeated addition, which is what is happening in this case, where the contractor gets $75 added to her account every time she sets another person up.

At this point you can just eliminate the other answer options except for B, so it is B.

But to double check... if you multiply 75 by 8, you would get $600, which is B.

Kingsley knows that 111 inch is about 2.542.542, point, 54 centimeters. He wants to write an equation he can use to convert any
lukranit [14]

Kingsley must multiply the measure in centimeters by 1 / 2.54 to get a unit conversion equation in inches.

<h3>How to derive a unit conversion formula?</h3>

Kingsley knows the conversion rate between inches and centimeters and wants to derive a formula. Both the inch and the centimeter are length units and we can represent it by the following ratio:

y / x = 2.54         (1)

Where:

  • y - Length, in centimeters.
  • x - Length, in inches

Then, we clear the variable x in (1) to find the unit conversion formula:

x = y / 2.54        (2)

Kingsley must multiply the measure in centimeters by 1 / 2.54 to get a unit conversion equation in inches.

What is solution to the system of equations? Y=5×+2 3×=-y+10
Sergio [31]
Y = 5x + 2
3x = y + 10

3x = y + 10
3x = 5x + 2 + 10
3x = 5x + 12
3x - 5x = 12
-2x = 12
x = -6

substitute x = -6 into y = 5x + 2

y = 5(-6) + 2
y = -30 + 2
y = -28

x = -6, y = -28

hope this helped, God bless!
