Consider the equation and its solution. Negative 15 (x minus box) = 25. Negative 15 x + 30 = 25. Negative 15 x = negative 5. x =

Solnce55 [7]

Answer:

-2

Step-by-step explanation:

Between the first two steps we see ...

$15(x-\boxed{^})=25\\\\15x+30=25$

Applying the distributive property to the first equation and comparing to the second, we see that ...

$-15\boxed{^}=30\\\\\boxed{^}=\dfrac{30}{-15}=-2$

The number in the box should be -2.

Anna is a teacher at an elementary school. She purchased 73 tickets to take the first-grade children and some parents on a field

Svetllana [295]

She bought 54 child tickets and 19 adult tickets.

Step-by-step explanation:

No. of tickets purchased = 73

Cost of tickets = $771

Cost of one child ticket = $9

Cost of one adult ticket = $15

Let,

Child ticket = x

Adult ticket = y

According to given statement;

x+y=73 Eqn 1

9x+15y=771 Eqn 2

Multiplying Eqn 1 by 9;

$9(x+y=73)\\9x+9y=657\ \ \ Eqn\ 3\\$

Subtracting Eqn 3 from Eqn 2;

$(9x+15y)-(9x+9y)=771-657\\9x+15y-9x-9y=114\\6y=114\\$

Dividing both sides by 6;

$\frac{6y}{6}=\frac{114}{6}\\y=19$

Putting y=19 in Eqn 1

$x+19=73\\x=73-19\\x=54\\$

She bought 54 child tickets and 19 adult tickets.
