Sure! Let's do this in order.
First, we can simplify the left side with the distributive property, getting us
8c-14
Next, we can simplify the right side with the distributive property, getting us 
8c-8-6.
That gives us 8c-14<8c-8-6.
We can subtract 8c from both sides, getting us
-14<-8-6
Simplify the right side to get
-14<-14
This inequality has no solution. This is because the variable is gone, and the remaining equation isn't true.

Calculate the mean, median, and mode of the following set of data. Round to the nearest tenth. 7, 3, 2, 1, 13, 8, 1, 5, 14, 11,
zysi [14]

Answer:

Mean = 7.3, median = 7, mode = 1.

Step-by-step explanation:

First arrange the data in order:

1 1 2 3 5 7 8 11 13 14 15

There are a total of 11 values.

Median = middle value = 7.

Mode = the most common number = 1.

Mean = sum / 11

=  80 / 11

=  7.3.

A company plans to enclose three parallel rectangular areas for sorting returned goods. The three areas are within one large rec
Svetlanka [38]

Answer:

The largest total area that can be enclosed will be a square of length 272 yards.

Step-by-step explanation:

First we get the perimeter of the large rectangular enclosure.

Perimeter of a rectangle =2(l + w)

Perimeter of the large rectangular enclosure= 1088 yard

Therefore:

2(L+W)=1088

The region inside the fence is the area

Area: A = LW

We need to solve the perimeter formula for either the length or width.

2L+ 2W= 1088 yd

2W= 1088– 2L

W = \frac{1088-2L}{2}

W = 544–L

Now substitute W = 544–L into the area formula

A = LW

A = L(544 – L)

A = 544L–L²

Since A is a quadratic expression, we re-write the expression with the exponents in descending order.

A = –L²+544L

Next, we look for the value of the x coordinate

L= -\frac{b}{2a}

L= -\frac{544}{2X-1}

L=272 yards

Plugging L=272 yards into the calculation for area:

A = –L²+544L

A(272)=-272²+544(272)

=73984 square yards

Thus the largest area that could be encompassed would be a square where each side has a length of 272 yards and a width of:

W = 544 – L

= 544 – 272

= 272 yards

Explain: how would you model 5 x 2/3
ELEN [110]
Well as you can see 5 x 2/3= 3 1/3 there is 7 steps to figure it out

1. set up the problem
5 x 2/3

2. put a 1 on 5 to make it a fraction
5/1 x 2/3

3. multiply and divide
(5 x 2) / (1/3)

4. find out the answer
10/3

5. turn the answer into a mixed fraction
10 divided by 3= 3.1 3 stays the same you don't need to say 1

6. it equals
3 1/3

7. so the answer is
3 1/3
