First you would need to find the square root of 50. Therefore, when x is t the power of 2, your x value would equal to the square root of 50.

EX:   x to the power of 2= 100.... x would equal to 10, since the square root of 100 is 10 and 10to the power of two ( or by itself twice) is equal to 100 it is similar to this equation....

your answer for your equation is 7.07106781187

Hope this helps:)

kirill [66]

Answer:

2p + 2d = 39 ____________(1)

8p + 10d = 174.50 _________(2)

Price of one drink is $9.25

Step-by-step explanation:

Let the price of a bag of popcorn be p.

Let the price of a drink be d.

Brianna spends a total of $39.00 on 2 bags of popcorn and 2 drinks. This implies that:

2p + 2d = 39 ____________(1)

Ava spends a total of $174.50 on 8 bags of popcorn and 10 drinks. This implies that:

8p + 10d = 174.50 _________(2)

We now have two system of equations which we can use to find the price of a bag of popcorn and drink:

2p + 2d = 39 ____________(1)

8p + 10d = 174.50 _________(2)

Multiply (1) by 4 subtract from (2):

 8p + 10d = 174.50 _______(2)

-<u> 8p + 8d = 156  </u>  __________(1)

        2d = 18.50

=>       d = $9.25

The price of one drink is $9.25
