Answer:
HCF X LCM= product of two numbers
14 x 840 = 42 x other number
other number= 14x840/42=280
Answer:
a = 7
Step-by-step explanation:
3(1 - 2a) = -3a - 18
3 - 6a = - 3a - 18
Add 18 to each side:
3 + 18 - 6a = - 3a - 18 + 18
21 - 6a = - 3a
Add 6a to each side:
21 - 6a + 6a = - 3a + 6a
21 = 3a
3a = 21
Divide each side by 3:
3a ÷ 3 = 21 ÷ 3
a = 7
Answer:
1) element - a member of a set
2) inequality - <, <, ,
3) line graph - visual tool used to illustrate solution sets
4) real number - positive or negative, rational or irrational numbers including zero
5) set - a collection or group of sets indicated by brackets, {}
6) set builder notation - a shorthand way to write a set
Step-by-step explanation:
The definitions of each of the terms are as follows:
Element: In a set, each member is called its element.
Inequality: The term inequality is used to compare two values. The sign used for inequalities are <, <, , .
Line graph: It gives the solution on a number line. This is the pictorial or visual representation of the solution.
Real number: All numbers that are rational, irrational positive or negative values are called real numbers.
Set: A set is a collection of data that are enclosed in two curly brackets. The data can be numbers, sets, etc.
Set builder notation: It is a shorthand notation used to represent a given set. It defines the data inside the set using appropriate mathematical symbols.
A postulate becomes a theorem when it is proven to be incorrect. if there are any exceptions to a postulate, it is theorem.
