You can write a statement like, what percent of 30 is 8 and form an equation:
x= 8*100/30 = 800/30 = approx. 26.6
 Concluding that 8 is approx 26.6% of 30

Hey there! :)

Blue: 8
Total: 30

Blue to total: 8/30 = 8 ÷ 30

Divide

8 ÷ 30 = 0.2666 = 0.27

0.27 = 27%

Your answer is 27%

Rounded to the nearest tenth: 26.6%
Rounded to the nearest whole: 27%

Hope this helps :)

Graph the line with the equation
pochemuha

The graph of the linear equation can be seen in the image below.

<h3 /><h3>How to graph the linear equation?</h3>

Here we have the linear equation:

y = (2/5)*x - 6

To graph it, we just need to find two points on the line, and then connect them with a line.

To find the points we just evaluate in two values of x.

if x = 0.

y = (2/5)*0 - 6 = -6

Then we have the point (0, -6)

If x = 5.

y = (2/5)*5 - 6 = 2 - 6 = -4

Then we have the point (5, - 4)

Now we can graph these two points and connect them with a line. The graph of the line can be seen below.

Express the product in simplest form.
Romashka [77]
\frac{8}{2x+8} *  \frac{ x^{2}-16 }{4}

1. Cross cancel
\frac{4}{2x+8}* \frac{ x^{2} -16}{1}

2. Multiply numerators
4*x²-16 = 4x²-64

3. Multiply denominators
2x+8*1 = 2x+8

\frac{4 x^{2} -64}{2x+8}

4. Divide
\frac{4 x^{2} -64}{2x+8} = 2x-8

5. Simplify
2(x-4)

Answer is 2(x - 4)

Iteru [2.4K]

Answer:

x=52

Step-by-step explanation:

90+34

124

180 (sum of all interior angles) - 124

56

x+72+56=180 (straight line)

x+128=180

 -128  -128

x=52

*replace to verify*

52+72= 124

124+56= 180 (straight line)

When x is 6, then y is <br><br>x: 2 3 4 5 6 <br>y:-3 -2 -1 0 ?<br><br>Complete the table.​
podryga [215]

Answer:

1

Step-by-step explanation:

for the equation of finding y is x - 5 = y

2 - 5 = -3

3 - 5 = -2

4 - 5 = -1

5 - 5 = 0

<u><em>6 - 5 = 1, </em></u> therefore, y is 1
