What is the value of the expression? 32+[4×(15÷3)]−5

Mathematics

3 0

Answer:

47

Step-by-step explanation:

32+[4×(15÷3)]−5

At first we have to apply "BODMAS" rule. According to the rule, we will work 1st bracket.

Hence,

32+[4×5]−5

Then, we will take 3rd bracket into consideration,

32+20−5

Then, we will use addition from the BODMAS rule-

52 - 5

Finally, subtracting 5 from 52, we can get

= 47

The value of the expression is 47.

A library contains 2000 books. There are 3 times as man non fiction books. Write and solve a systems of equations to determine t
icang [17]

Answer:

The number of fiction books is <u>500</u> and non fiction books is <u>1500</u>.

Step-by-step explanation:

Given:

Total book library contains = 2000.

There are 3 times as many non fiction books as fiction books.

Now, to determine the number of non fiction books and fiction books.

Let the fiction books be x.

And the non fiction books be 3x.

Total books = 2000.

Now, to get the number of non fiction books and fiction books we put an equation:

3x+x=2000.

4x=2000.

Dividing both sides by 4 we get:

x=500.

Fiction books = 500.

Non fiction books = 3x=3\times 500=1500.

Therefore, the number of fiction books is 500 and non fiction books is 1500.
