A total of 479 tickets were sold for the school play. They were either adult tickets or student tickets. There were 71 fewer stu
irina [24]

Say the number of adult tickets is x. That means the number of student tickets is 71 less, making it x - 71.

We can add the number of student and adult tickets, because we know their sum is 479.

x + x - 71 = 479

Now, we solve for x.

2x - 71 = 479

2x = 550

x = 275

So, there were 275 adult tickets sold.

Which is a solution to the equation?
stiks02 [169]
If you would like to know the solution to the equation (x - 2) * (x + 5) = 18, you can calculate this using the following steps:

(x - 2) * (x + 5<span>) = 18
</span>x^2 + 5x - 2x - 10 = 18
x^2 + 3x - 28 = 0
(x + 7) * (x - 4) = 0
1. x = - 7
2. x = 4

The correct result would be x = - 7.

ANSWER

a=-2, b=3

EXPLANATION

The given equation is

(a {x}^{2})( - 6 {x}^{b}  ) = 12 {x}^{5}

Recall that:

{a}^{m}  \times  {a}^{n}  =  {a}^{m + n}

We simplify the left hand side to get:

- 6a {x}^{2 + b}  = 12 {x}^{5}

For this equation to be true, we must have:

-6a=12 and 2+b=5

This implies that,

a=-2 and b=3
