Step-by-step explanation: you need to divide 2 by one-third. So, set it up. 2/1 divided by 1/3. The method I use is keep, change, flip. Keep 2/1, and flip 1/3 to 3/1. Now you have 2/1 multiplied by 3/1 which is 6.
Answer:19 students
Step-by-step explanation:
First you would add together all the students that you know take a math class. So you would add 14+20+7 to get 41 students. So now you know that that many students take a math class. So you would do 60-41 because 60 is your overall number of students. After you subtract them you should get 19 which is your answer-19 students don’t take either of the subjects
The value of the expression 3ac - b² - c² is -61.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The expression will be solved as below:-
3ac - b² - c² = ( 3 x 4 x -3 ) - ( 4 )² - ( -3 )²
= ( -36 - 16 - 9 )
= ( -61 )
Therefore, the value of the expression 3ac - b² - c² is -61.
