A local sporting event charges $6 for each adult ticket and $3.50 for each child ticket. If the stadium sold a total of 65 adult
tatyana61 [14]
45 adult tickets were sold.

adult tickets = a
childrens tickets = b

a + b = 65
6a + 3.5b = 340

Subtract a from the equation on top to get b = 65 - a
Substitute into the second equation 6a + 3.5(65 - a) = 340
Simplify to make 6a + 227.5 - 3.5a = 340
6a - 3.5a = 340 - 227.5
Combine like terms so that 2.5a = 112.5
Divide both sides by 2.5 to isolate the variable a

Your final answer is a = 45

The length of the floor is 32 m longed than it’s witdth and there is greater than 200 square meters. You will cover the floor co
Vilka [71]

Answer:

Step-by-step explanation:

The area of the floor A = Length * Width

Given

A = 200 square meters

If the length of the floor is 32 m longed than it’s width then;

L = 32+W

A = LW

200 = (32+W)W

200 = 32W + W²

W²+32W-200 = 0

W = -32±√32²+800/2

W = -32±42.71/2

W =  -32+42.71/2

W = 10.71/2

W = 5.35 m

L = 32+5.35

L = 37.35m

Hence the dimension is  5.35ft by 37.35m

6 minutes

Step-by-step explanation:

  1. Set up the proportion as these two fractions equal to each other

9/3 = 18/x

2. Cross multiply so that 9*x=18*3

3. 9x=54, so now you divide 54 by 9

and this will give you
