Answer:

First, follow the first step in PEMDAS so you would do the parenthesis first followed by exponents, multiplication, division, addition, then subtraction

Step-by-step explanation:

6 + 8 ÷ 4 (4*5)^2

6 + 8 ÷ 4 + 20^2

6 + 8 ÷ 4 + 400

6 + 2 + 400

= 408

Problem 2

<h3>Answer: Choice C) 3+5 = 5+3</h3>

The commutative property of addition is the idea of adding any two (or more) numbers in any order we want. In the example above, the 3 and 5 swap places. You can think of them commuting back and forth as if they are going from work to home (or vice versa).

A similar property is the commutative property of multiplication. An example would be 2*3 = 3*2 (shown in choice B).

Problem 3

The list of choices is not showing up, so I cannot answer this one. Please update.

Five friends bought admission tickets the museum and a box lunch.the cost of each admission ticket was $11.75.each box lunch cos
slega [8]
Cost of the admission tickets: 11.75x

Cost of the box lunch: 5x

Expressions to find the total cost = (1) ....... 11.75x + 5x

That is equivalent to: (2) .......... (11.75 + 5)x = 16.75x.

Now calculate the cost for x = 5 using both expressions:

1) 11.75(5) + 5(5) = 58.75 + 25 = 83.75

2) 16.75(5) = 83.75

Of course you got the same result with both expressions.
