Answer:

senior tickets sold: 12

child tickets sold:8

Step-by-step explanation:

Let

x= amount of senior tickets sold

y= amount of child tickets sold

For the first equation, it should look like:

200=14x+4y

For the second equation, it should look like:

92=7x+y

So this is a systems of equations problem. So I will use substitution as it is easier:

1.) Take one of the equations (in this case ill take 92=7x+y) and make one variable have a value, in this case ill isolate the y.

$(-7x)92=7x+y(-7x)$

$y=92-7x$

2.) Take the value of y and plug it into "y" into the other equation to solve "x"

$200= 14x + 4(92-7x)\\200=14x+368-28x\\(-368)200=-14x+368(-368)\\(-\frac{1}{14})* -168=-14x*(-\frac{1}{14} )\\\\x=12$

(editor's note:instead of dividing it by 14, I multiply by 1/14 as it would look complicated in the equation solving steps)

3.) Then plug the value of "x" to one of the equations to solve for "y" (which I'll use the 92=7x+y)

$92=7(12)+y\\(-84)92=84+y(-84)\\y=8$

The number of years from the start of the Great Depression to the first presidential election of Richard Nixon is six years less

svp [43]

Answer:

Raul's age is 15 years.

Step-by-step explanation:

r represents Raul's age.

The number of years from the start of the Great Depression to the first presidential election of Richard Nixon is six years less than three times Raul's age.

The first presidential election happened 39 years after the Great Depression and six years less than three times Raul's age is 3r - 6.

Therefore, 3r - 6 = 39

Add 6 to both sides.

3r = 45

Divide both sides by 3.

r = 15

Hence, Raul's age is 15 years.

You are in charge of drinks for a community barbecue. You need to supply at least 120 cups of beverage to provide enough for the

olga nikolaevna [1]

Answer:

You have 112 cups of beverage

Step-by-step explanation:

* Lets explain how to solve the problem

- You need to supply at least 120 cups of beverage to provide enough

for the projected number of people that will attend

- Assume that a cup can fill by 8 fl. oz. (American standard)

- You have received the following donations

- Enough mix to make 4 gallons of lemonade

∴ You have 4 gallons of lemonade

∵ 1 gallon = 128 oz.

∴ 8 gallons = 4 × 128 = 512 oz.

∴ You have 512 oz. of lemonade

∵ You can fill one cup by 8 oz.

∴ The number of cups of lemonade = 512 ÷ 8 = 64 cups

- 6 bottles of fruit juice that each contain 64 fl. oz

∵ 6 × 64 = 384

∴ You have 384 oz. of fruit juice

∵ You can fill one cup by 8 oz.

∴ The number of cups of fruit juice = 384 ÷ 8 = 48 cups

- Now add the number of lemonade cups to the number of fruit

juice cups

∵ There are 64 of lemonade cups

∵ There are 48 fruit juice cups

∴ The total number of cups = 64 + 48 = 112 cups

* You have 112 cups of beverage
