Answer:

Reason given in step 2. is incorrect. It should read; "Distributive Property."

Step-by-step explanation:

The reason given to go from :

2 (3x +4) = 56  to 6x + 8 = 56

is NOT "Multiplication Property of Equality" because one is not multiplying both sides of the equality by a number. The property that is being used is the Distributive Property on the left side of the equation in order to remove the grouping symbols (parenthesis) performing the implied multiplication of the external factor times each term of the binomial in parenthesis.

Answer:  3/4,  because the probability of renting a comedy is 1/4

================================================================

Explanation:

We have 36+26+30+28 = 120 students. 30 of which rented a comedy.

The probability of renting a comedy is 30/120 = (30*1)/(30*4) = 1/4

The probability of not renting a comedy is 1 - (1/4) = 4/4 - 1/4 = (4-1)/4 = 3/4.

Or you could say that 1/4 = 0.25, so 1-0.25 = 0.75 which converts to the fraction 3/4.

If you had 4 people and 1 of them rents a comedy, then the other 3 hasn't rented a comedy.

insens350 [35]

Answer:  $13,475

<u>Step-by-step explanation:</u>

1st hour:  350 people bought tickets --> 350 × $17.50 = $6,125

2nd hour: 350(1.2) people bought tickets --> 350(1.2) × 17.50 = $7350

Total amount = 1st hour + 2nd hour

                      = $6,125 + $7,350

                      = $13,475
