What we know:
- number of meeting rooms = m
- chairs in each meeting room = 325

Since we need an equation to represent the number of chairs in m meeting rooms, we would multiply the amount of chairs per meeting room (325) by m. This amount is c. So the equation becomes:

c = 325m

Now the question asks for the amount of chairs if there are 7 meeting rooms in the hotel. To find this, substitute 7 for m into c = 325m.

c = 325m
c = 325(7)
c = 2275

Answer:
The equation is c = 325m, and the amount of chairs if m equals 7 is 2,275.

C = m* 325, so if m = 7, then,

C = 2275

Each marble bag sold by Laura's Marble Company contains 3 red marbles for every 5 blue marbles.

If a bag has 15 red marbles, how many blue marbles does it contain?

well, we know there are 3 red ones for every 5, so how many blue ones are there when there are 15 red ones?

$\bf \begin{array}{ccll}red&blue\\\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\3&5\\15&b\end{array}\implies \cfrac{3}{15}=\cfrac{5}{b}\implies b=\cfrac{15\cdot 5}{3}\implies b=25\\\\\\\stackrel{\textit{total marbles}}{red+blue}\implies 15+25$

Look at this graph:

amm1812

For the given graph , slope of the line is equal to ( 1 / 2 ).

As given in the question,

Form the given graph,

Scale is given by,

On x-axis each unit of the graph represent 1 unit.

On y- axis each unit of the graph represent 1 unit.

Consider two coordinates from the line of the graph,

( x₁ , y₁ ) = ( 1, 2 )

( x₂ , y₂ ) = ( 3, 3 )

Slope of the line = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substitute the value in the formula of the slope we get,

Slope of the line = ( 3 - 2 ) / ( 3 - 1 )

⇒ Slope of the line = 1 / 2

Therefore, for the given graph , slope of the line is equal to ( 1 / 2 ).

X+5y+2-7xx + 5 y + 2y − 7x

kari74 [83]

X + 5y + 2 - 7x + 5y + 2y - 7x

First collect like terms (the numbers that have the same letters after them):

x - 7x - 7x = -13x

5y + 5y + 2y = 12y

Then put these back into the expression:

2 - 13x + 12y

A car driving on a straight path travels about 260 feet in 3 seconds. Rounded to the nearest second, approximately how many seco

myrzilka [38]

Hello!

Let's write this as a proportion below.

$\frac{feet}{seconds} = \frac{260}{3} = \frac{5,280}{s}$

Now we cross multiply and divide to find x.

$s= \frac{5,280(3)}{260} = \frac{15840}{260}$ ≈ 61

Therefore,the car takes about 61 seconds for the car to drive a mile.

I hope this helps!
