Which operation should be performed first according to the order of operations? 44 • 2 – [(5 + 20 • 3) – 12] + 16 ÷ 2 A. 44 • 2 B. 5 + 20 C. 20 • 3 D. 16 ÷ 2

Answers

Answer 1
Answer:

Answer:

The first operation that will be applied to the given expression 44 • 2 – [(5 + 20 • 3) – 12] + 16 ÷ 2 is:

20.3

Hence, option: C is correct.

Step-by-step explanation:

We are asked to find which operation should be operated first to the given expression:

44 • 2 – [(5 + 20 • 3) – 12] + 16 ÷ 2

The operation are operated according to the rule:

PEMDAS

P----Parenthesis

E----Exponential

M----Multiplication

D-----Division

A-----Addition

S-----Subtraction

Hence, in the given term we have the parenthesis term as:

5+20.3 among this also we have to give first priority to multiplication and then to addition.

Hence, the first operation that will be applied is:

20.3
Answer 2
Answer: Just use PEMDAS 
P) parentheses
E) exponents
M) multiplication 
D) Divison
A) addition
S) subtraction
Do it in that order  and you will surely get a good grade on something

How many campers would be in each cabin if the ratio of cabins to campers was 15 to 225? Explain

Answers

Ratio is of the form Cabin : Campers or Cabin / Campers.

Campers = 225

so Ratio = Cabin / Campers = 15 / 225 = 1/15

Ratio = 1 : 15

Explain how algebra tiles represent like terms and zero pairs

Answers

Final answer:

Algebra tiles visually represent like terms by using the same tiles to represent the same variables or numbers. Zero pairs are represented by combining a positive and negative tile to represent 'zero', which is crucial in simplifying expressions or solving equations.

Explanation:

In mathematics, specifically in algebra, algebra tiles are a visual tool that are often used to teach concepts. These tiles usually include small squares to represent the number 1, bars to represent variables, and large squares to represent squares of variables.

They are used to represent like terms, which in algebra are terms that contain the same variables raised to the same power. For instance, if you have 3x and 2x, these can be considered like terms because they both contain the variable 'x'. In the context of algebra tiles, you would use three 'x' bars to represent 3x and two 'x' bars to represent 2x.

On the other hand, zero pairs are pairs of numbers that combine to give zero. Using algebra tiles, a zero pair can be represented by placing a positive tile and a negative tile together, which would cancel each other out, effectively representing 'zero'. This concept is important when simplifying expressions or solving equations.
