Senior tickets (x)

Child tickets (y)

First day: 3x + 5y = 70

second day: 12x + 12y = 216

Solve the system of equations (use elimination)

Multiply first equation by -4 -4(3x + 5y = 70), which makes it

-12x - 20y = -280

(+)12x + 12y = 216 add to second equation

-8y = -64

divide by -8. y = 8

Plugin the y value to either equation ( I will choose first equation)

3x + 5(8) =70

3x+ 40 = 70

3x = 30

x = 10

Senior tickets are $10, child tickets are $8

Which of the following is equivalent to the radical expression below?

SCORPION-xisa [38]

For this case we must indicate an expression equivalent to:

$\sqrt {10x ^ 7}$

By definition of properties of powers and roots we have that:

$\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}$

Then, we can rewrite the expression as:

$10 ^ {\frac {1} {2}} * x ^ {\frac {7} {2}}$

OPTION A
