What is the value of 1-18+25 if you subtract then add? If you add then subtract? Why is the order of operations necessary?

Answers

Answer 1

Answer: In this problem it just goes left to right, 1-18+25 = -17+25 = 8
(1-18)+25-17+25=8
When you do addition and subtraction they are reversible so you just go left to right

Let set A = {odd numbers between 0 and 100} and set B = {numbers between 50 and 150 that are evenly divisible by 5}.What is A ∩ B?

{50, 55, 60, 65, 70, 75, 70, 85, 90, 95}
{55, 65, 75, 85, 95}
{all odd numbers between 1 and 99}
{numbers between 1 and 150 that are evenly divisible by 5}

Answers

Answer: {55, 65, 75, 85, 95}

Step-by-step explanation:

Given: A = {odd numbers between 0 and 100}

B= {numbers between 50 and 150 that are evenly divisible by 5}

Thus, A={1,2,3,4,5,6,7,8,.......99}

and B={55,60,65,70,75,80,85,90,95......145}

The notation A ∩ B means A intersection B which is the set of elements that are common in set A and in set B.

Now, $A\bigcap B=\left \{ 55,65,75,85,95 \right \}$

The elements of set A ∩ B are {55, 65, 75, 85, 95}

The sets are given as:

A = {odd numbers between 0 and 100}

B= {numbers between 50 and 150 that are evenly divisible by 5}

The above means that:

A = {1,2,3,4,5,6,7,8,.......99}

B = {55,60,65,70,75,80,85,90,95......145}

To calculate set A ∩ B, we list the common elements in both sets, without repetition.

So, we have:

A ∩ B = {55, 65, 75, 85, 95}

Hence, the elements of set A ∩ B are {55, 65, 75, 85, 95}

Answer: smaller number is 23, larger number is 35

Step-by-step explanation:

Let the smaller number be y

The larger number will be y+12

The addition of the numbers is 58.

y+(y+12) = 58

y+y+12 = 58

2y+12 = 58

2y= 58-12

2y= 46

y= 46/2

y= 23

The smaller number is 23

Larger number will be 23+12=35

Answer:

the larger number is 35 and the smaller one is 23
