Answer:

$3x+$5y=C and the total cost is $ 78

Step-by-step explanation:

the equation first is going to be  $3x+$5y=C

x: small balloons

y: large balloons

c: total cost

Now to find the how much the total cost is, you should substitute the variables  and then solve the equation.

x: 11

y:9

3(11)+5(9)= 33+45

Write the following sentence into an expression using x as your variable: Myrna and Tom collect stamps. Tom has four more than h
balandron [24]

Answer: f(x) = x/2 + 4.

where f(x) is the number of stamps that Tom has, and x is the number of stamps that Myrna has.

Step-by-step explanation:

The statement is:

"Tom has four more than half the stamps that Myrna has"

For how is written, we can model the number of stamps that Tom has as a function f(x).

f(x) represents the number of stamps that Tom has, and x is the number of stamps that Myrna has.

Then:

"four more than a number" is written as:

N + 4 (where N is the number)

"Half the stamps that Myrna has" is written as:

x/2.

Then the whole statement can be modeled as:

f(x) = x/2 + 4.

notice that we have x/2, and f(x) must be a whole number, so Myrna must have an even number of stamps (in that case x/2 will be integer)
