Consider this system of equations and the partial solution below.

Inga [223]

The first equation will turn into -18x -6y = -18, and the second equation will turn into 14x + 6y = 18. The y terms will cancel out when you add the equations together.

I don't get what there asking.

Angelina_Jolie [31]

Answer:

86 adults and 270 children

Step-by-step explanation:

Let x = # of adult tickets;

then the number of children tickets is (356-x).

Write the total money equation (revenue equation)

$1.75*(356-x) + 2.25x = 666$ dollars.

From the equation

$x = \frac{666-1.75*356}{2.25-1.75} = 86$

ANSWER. 86 adults and 356-86 = 270 children.

CHECK.

$86*2.25 + 270*1.75 = 666$ dollars. ! Correct !

Need help with this question.

We have this equation:

$\log(x) + \log(x + 99) = 2$

First, combine both logarithms using the multiplication property and simplify the expression.

$\log[x(x + 99)] = 2$

$\log[ {x}^{2} + 99x ] = 2$

Now, use the definition of logarithm to transform the equation.

${10}^{2} = {x}^{2} + 99x$

${x}^{2} + 99x - 100 = 0$

Finally, use the quadratic formula to solve the equation.

$x = \frac{ -99 ± \sqrt{ {99}^{2} - 4 \times 1 \times ( - 100)} }{2 \times 1}$

With this, we can say that the solution set is:

x = 1
x = -100

We cannot choose x = -100 as a solution because we cannot have a negative logarithm. The only solution is x = 1.
