You are buying balloons for a party. A small balloon costs $3 A large balloon costs $5 Write an algebraic expression for the cost of x small balloons and y large balloons. Then find the total cost for 11 small balloons and 9 large balloons. Please solve! I'm stuck!

$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

78

78 dollars

Step-by-step explanation

x=33  

y=45

have to leave.  Will check back with equation

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
