Answer:

Total number of people in the concert

= 186

Step-by-step explanation:

There are 80 people in level 2

Then in level one

The dimensions of the room are 62 feet by 31 feet.

15 people fit in a 3 feet by 6 feet space.

Area of the room= 62*31= 1922 feet²

area of 15 people space= 3*6= 18 feet²

To know how many 15 people we get in the 2nd level

=Area of room/area of 15 people space

= 1922/18

= 106.77

= 106 (we round down because this is human being.)

Total number of people in the concert

= 106+80

= 186

I need help with this V-4=v+2+7v-42 ??

zubka84 [21]

Answer:

$\boxed{\bold{v \ = \ \frac{36}{7}}}$

Step-by-step explanation:

Subtract v from both sides

$\bold{v-4-v=v+2+7v-42-v}$

Simplify

$\bold{-4=2+7v-42}$

Switch sides

$\bold{2+7v-42=-4}$

Group like terms

$\bold{7v+2-42=-4}$

Subtract the numbers: 2 - 42 = -40

$\bold{7v-40=-4}$

Add 40 to both sides

$\bold{7v-40+40=-4+40}$

Simplify

$\bold{7v=36}$

Divide both sides by 7

$\bold{\frac{7v}{7}=\frac{36}{7}}$

Simplify

➤ $\bold{v=\frac{36}{7}}$

last summer, at camp okey-fun-okey, the ratio of the number of boy campers to girl campers was 8:7. If there were a total of 195

Evgen [1.6K]

The ration of boy campers to total campers is 8:15, and the ratio of girl campers to total campers is 7:15. Using this information, we can answer this question by setting up proportions.

For boys:

$\frac{8}{15} =\frac{x}{195}$

*Cross multiply*

15x=1560

*Divide both sides by 15*

x=104

There are 169 boy campers.

For girls:

$\frac{7}{15} =\frac{x}{195}$

*Cross multiply*

15x=1365

91=x

There are 91 girl campers.

Hope this helps!!

Find the value of X.

Oksanka [162]

Answer:

x =25

Step-by-step explanation:

This is an isosceles triangle because RS = ST

that means <r = <STR

4x-70 = STR

<STR + <STU = 180 straight line

subtract < STU from each side

<STR = 180 -<STU

we know angle stu = 6x

<STR = 180 -6x

we can substitute this into 4x-70 = STR

4x-70 = 180 -6x

add 6x to each side

4x+6x -70 = 180 -6x+6x

10x -70 = 180

add 70 to each side

10x-70+70 = 180+70

10x=250

divide by 10

10x/10 = 250/10

x =25
