Question 1

coefficient

Answer 1

the numeric part of a variable term that is being multiplied by the variable

Question 2

variable

Answer 2

written a numerical part has a coefficient of one

Question 3

constants

Answer 3

numbers by themselves

Question 4

determine the parts of the algebraic equation

8 - 10x + 2 = 11

Answer 4

terms: 8, -10x, 2, 11
variable terms: 10x
variables: x
coefficients: -10
constants: 8, 2, 11

Question 5

addition principle

Answer 5

states that in a true equation where a=b, adding any number c to both sides of the equation, making it
a + c = b + c

Question 6

multiplication principle

Answer 6

states in a true equation a=b, multiplyinh both sides of the equation by any number c, making it ac = bc

Question 7

division principle

Answer 7

division by c is the same as multiplication by the reciprocal 1/c as long as c does not equal 0

Question 8

clear the equation of fractions

Answer 8

to do this:
multiply both sides by a common denominator of both fractions
(the least common denominator)

Question 9

clear the equation of decimals

Answer 9

to do this:
not that the greatest number of decimal places in any of the decimals is 2 so we multiple both sides by 100
