Iwill mark plus 25 pts. a party rental company has chairs and tables for rent. the total cost to rent 8 chairs and 4 tables is $ 45 . the total cost to rent 3 chairs and 2 tables is $ 21 . what is the cost to rent each chair and each table?

Let C= cost to rent each chair

Let T= cost to rent each table

8C + 4T = 45

3C + 2T = 21

Multiply the 2nd equation by (-2) and then add the equations together

8C + 4T = 45

-6C - 4T = -42

2C = 3

C = 3/2 = 1.5

Plug this in to the 1st equation to solve for T

8C + 4(3/2) = 45

8C + 6 = 45

8C = 39

C = 36/8 = 4. 5

So the cost to rent each chair is $1.50 and the cost to rent each table is $4.50

Hope this helped ‘cuz it took me forever! :)

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
