Need help with systems of equations

Mathematics
1 answer:
OLEGan [10]2 years ago
8 0

Step-by-step explanation:

x + y = 14

this gives us

y = 14 - x

2x = y - 5

we use the first equation in the second

2x = 14 - x - 5 = 9 - x

3x = 9

x = 3

y = 14 - x = 14 - 3 = 11

the smallest number is 3 or 03.

Verizon [17]

Answer:

On that day <u>1500 children</u> and <u>700 adults</u> attended.

Step-by-step explanation:

Given:

There is a carnival. Children are $1.50 and adults are $4.

The total amount of money raised was $5050.

On this particular day there 2200 in attendance.

Now, to find the children and adults attended on that day.

Let the children attended be x.

And the adults attended be y.

The total number in attendance:

x+y=2200

⇒ x=2200-y........( 1 ).

Now, the total amount of money raised:

1.50x+4y=5050

Putting the equation ( 1 ) in the place of x we get:

⇒ 1.50(2200-y)+4y=5050

⇒ 3300-1.50y+4y=5050

⇒ 3300+2.50y=5050  

<em>Subtracting both sides by 3300 we get:</em>

⇒ 2.50y=1750

<em>Dividing both sides by 2.50 we get:</em>

⇒ y=700.

The adults attended = 700.

Now, putting the value of y in equation ( 1 ) we get:

x=2200-700

⇒ x=1500.

The children attended = 1500.

Therefore, on that day 1500 children and 700 adults attended.
