Answer:

259 students

Step-by-step explanation:

First, find how many will check out science fiction books

350(0.14)

= 49

Find how many will check out sports books

350(0.12)

= 42

Subtract these amounts from 350

350 - 49 - 42

= 259

So, she should expect 259 students not to check out science fiction and sports books

Anyone please answer me ,<br> Please solve this question
Mamont248 [21]

Answer:

67

Step-by-step explanation:

Multi-Inscribed Quadrilateral: 15

Bananas: 4

Clock: 3

Therefore, we can substitute for the last equation the values, so it would become:

3 + 4 + 4 x 15 = ?

First, we solve the multiplication according to PEMDAS.

4 x 15 = 60

Then, we can add from left to right.

3 + 4 + 60 = ?

3 + 4  = 7

7 + 60 = 67

Therefore, our answer would be 67.
