Parts of an Algebraic Expression
What is the constant in the following expression?
12xy + x + 5
5
5 decreased by k
5 - k
29 more than k is 59
k + 29 = 59
What are the variables in the following expression?
9m - mn + 7
m and n
the total of 18 and m
18 + m
twice the difference of n and 18 is 92
2(n-18)=92
List down the variables, coefficients, constants, and terms of the following expression.
83k - h + 9h
Variables: k, h
Coefficients: 83, 9
Constants: None
Terms: 83k, h, 9h
15 subtracted from the product of 8 and x
8x - 15
29 added to the difference of 32 and t is 83
29 + (32 - t) = 83
List down the variables, coefficients, constants, and terms of the following expression.
27 + 15ab - c - 3a
Variables: a, b, c
Coefficients: 15, 3
Constants: 27
Terms: 27, 15ab, c , 3a
What words switch the order of the variables and numbers given in an expression?
"than" and "from"
What is the difference between an expression and an equation?
An equation is a solved expression. (Has an equal sign and answer.)
Create an algebraic expression with 2 variables, 1 coefficient, and 1 constant.
Example: x-2y+4
Molly has 8 more apples than Francine.
Write an algebraic expression to represent the number of apples Molly has. Use f to represent the number of apples Francine has.
f + 8
Jordan spent $45 on Easters grams that cost $5 each.
Write an algebraic expression to represent the number of Easter grams Jordan bought has. Use e to represent the number of Easter Grams.
5e = 45
