Answer

x = 28

Explanation

3/8x + 15/2 = 18

Step 1. Subtract 15/2 from both sides

3/8x = 15/2 - 15/2 = 18 - 15/2

3/8x = 21/2

Step 2. Multiply both sides by 8/3

(8/3) * (3/8x) = (8/3) * (21/2)

Step 3. Answer

Therefore x is 28.

A recreational court is three times as long as it is wide. If the perimeter is 224 ft, find the dimensions of the court?

ella [17]

The dimensions of court are:

Length = 84 feet and Width = 28 feet

Step-by-step explanation:

Given

Perimeter of court = 224 ft

Let l be the length and w be the width

then

l = 3w

The formula for perimeter of rectangle is:

$P = 2(l+w)$

Putting the value

$224 = 2(3w+w)\\224 = 2(4w)\\224 = 8w$

Dividing both sides by 8

$\frac{8w}{8} = \frac{224}{8}\\w = 28$

Length:

$l = 3w\\l = 3*28\\l = 84 ft$

Hence,

The dimensions of court are:

Length = 84 feet and Width = 28 feet

Answer:

I think it's 160 square inches. Try L x W x H (length multiplied by width multiplied by height). So that would mean 4 x 5 = 20 x 8 = 160,

hope this helps!

The function f(x) is represented by this table of values. x f(x) -4 -12 -3 -5 -2 0 -1 3 0 4 1 3 Match the average rates of chang

Y_Kistochka [10]

Answer:

6 goes with [-4,-2]

1 goes with [-2,1]

2 goes with [-3,1]

4 goes with [-4,0]

Step-by-step explanation:

x f(x)

-----------

-4 -12

-3 -5

-2 0

-1 3

0 4

1 3

Before I continue, you need to know what f(a) means. f(a) means find x=a and the value that corresponds to it is f(a).

That is f(-4)=-12 from row 1.

That is f(-3)=-5 from row 2.

That is f(-2)=0 from row 3.

That is f(-1)=3 from row 4.

That is f(0)=4 from row 5.

That is f(1)=3 from row 6.

Average rate of change on $[a,b]$ is given by the formula:

$\frac{f(b)-f(a)}{b-a}$ or you could use $\frac{f(a)-f(b)}{a-b}$ .

So the average rate of change on [-4,-2] is given by

$\frac{f(-4)-f(-2)}{-4-(-2)}=\frac{-12-0}{-2}=6$

The average rate of change on [-2,1] is given by

$\frac{f(1)-f(-2)}{1-(-2)}=\frac{3-0}{3}=1$

The average rate of change on [-3,1] is given by

$\frac{f(1)-f(-3)}{1-(-3)}=\frac{3-(-5)}{4}=\frac{8}{4}=2$

The average rate of change on [-4,0] is given by

$\frac{f(0)-f(-4)}{0-(-4)}=\frac{4-(-12)}{4}=\frac{16}{4}=4$
