Write a system of equations to describe the situation below. Sparkles the Clown makes balloon animals for children at birthday parties. At Jenny’s party, she made 2 balloon poodles and 2 balloon giraffes, which used a total of 12 balloons. For Roger’s party, she used 27 balloons to make 4 balloon poodles and 5 balloon giraffes. How many balloons does each animal require?

Each animal require 3 balloons.

Step-by-step explanation:

Let 'x' be the number of balloon poodles.

Let 'y' be the number of balloon giraffes.

Multiply eqn (1) by 2 and subtract eqn(2) from eqn(1),

   4x+4y = 24

(-) 4x+5y = 27

      -y = -3  

⇒ y=3

⇒ Number of balloon giraffes = 3

Substitute y=3 in eqn(1)

⇒ 2x+2(3) = 12

⇒ 2x+6=12

⇒ x = 6/2

⇒ x = 3

⇒ Number of balloon poodles = 3

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
