Stacey is selling tickets to the school play. The tickets are $8 for adults and $3 for children. She sells twice as many adult t

Leona [35]

48 adult tickets and 24 children tickets were sold.

Step-by-step explanation:

Given,

Cost of one adult ticket = $8

Cost of one child ticket = $3

Total worth of sold tickets = $456

Let,

Number of adult tickets sold = x

Number of child ticket sold = y

According to given statement;

8x+3y=456 Eqn 1

x = 2y Eqn 2

Putting value of x from Eqn 1 in Eqn 2

$8(2y)+3y=456\\16y+3y=456\\19y=456$

Dividing both sides by 19

$\frac{19y}{19}=\frac{456}{19}\\y=24$

Putting y=24 in Eqn 2

$x=2(24)\\x=48$

48 adult tickets and 24 children tickets were sold.

Is 7 a solution of 5x - 3 = 12?

V125BC [204]

Answer:

Step-by-step explanation:

5x - 3 = 12

5x=12+3

x=15/5=3

x=3

substitute x with 7 to find if it is a solution :

5(7)-3=12

35-3 ≠12 ( so no 7 is not a solution)
