Answer:

V = 3

Step-by-step explanation:

<u><em>Given:</em></u>

<em>Perimeter of the pentagon is 52 units.</em>

<em>Solve for value of v.</em>

<u>Solve:</u>

<em>Let first put it into a equation base on the given;</em>

<em>6v + 8 + 8 + 3v + 1 + v + 5 = 52</em>

<em>Add the numbers</em>

<em>6v + 22 + 3v + v = 52</em>

<em>Combine like terms</em>

<em>10v + 22 = 52</em>

<em>Subtract 22 from both sides</em>

<em>10v + 22 - 22 = 52 - 22</em>

<em>Simplify</em>

<em>10v = 30</em>

<em>Divide both sides by 10</em>

<em>10v/10 = 30/10</em>

<em>Simplify</em>

<em>v = 3 </em>

<em>Check Answer:</em>

<em>6(3) + 8 + 8 + 3(3) + 1 + (3) + 5 </em>

<em>18 + 8 + 8 + 3(3) + 1 + (3) + 5 </em>

<em>18 + 16 + 9 + 1 + 8</em>

<em>18 + 16 + 9 + 9</em>

<em>18 + 16 + 18</em>

<em>36 + 16</em>

<em>52</em>

<em>Hence, v = 3</em>

Step-by-step explanation:

1) add all sides into an equation to solve for v.

3v+1+v+5+6v+8+8=52

2) combine like terms

3v+1+v+5+6v+8+8=52

10v+22=52

3) subtract 22 from both sides

10v+22-22=52-22

10v=30

4) divide both sides by 10

10v/10=30/10

v=3

You could expect about 1,248 students to play at least 4 hours every week.

Our tables have 100 students involved. All but 4 of the students are in the category of at least 4 hours. That is 96%.

Therefore, we simply need to multiply 0.96 by 1300 to get the estimated amount.

0.96 x 1300 = 1248

Em 1 Graph the system of equations. { x−y=6 ,4x+y=4
muminat

Graphing the system of equations is shown in figure attached.

Solution set is (2,-4). The lines will intersect at (2,-4)

Step-by-step explanation:

We need to graph the system of equations. x-y=6 ,4x+y=4

First we will find value of x and y

Let:

x-y=6\,\,eq(1)\\4x+y=4\,\,eq(2)

Add eq(1) and eq(2)

x-y=6\,\,\\4x+y=4\,\,\\------\\5x=10\\x=10/5\\x=2

Putting value of x in eq(1) and finding y

x-y=6\\2-y=6\\-y=6-2\\-y=4\\y=-4

So, y=-4

Graphing the system of equations is shown in figure attached.

Solution set is (2,-4). The lines will intersect at (2,-4)

Describe a way to calculate 304-81 mentally by using reasoning other that the common subtraction algorithm. Then write a coheren
Natasha_Volkova [10]

Answer:

See explanation

Step-by-step explanation:

To subtract mentally 81 from 304, complete following steps:

<u>Step 1:</u> Write number 304 as

304=300+4\\ \\304=200+100+3+1\\ \\304=200+20+80+3+1

<u>Step 2: </u>Write number 81 as

81=80+1

<u>Step 3: </u>Now subtract 80 and 1 from number 304:

304-81=(200+20+80+1+3)-(80+1)\\ \\304-81=200+20+3\\ \\304-81=223
