Evaluate. 7m - 9n when m = 7 and n = 5
7(7) - 9(5) = 49 - 45 = 4
Evaluate. 20 - 3n when n = 2
20 - 3(2) = 20 - 6 = 14
Write an expression. 13 more than the product of m and 5
13 + 5m
What is the coefficent of y? 7xy + 2y - 9
2
Evaluate. 3x + 4y - 16 / 2 when x = 8 and y = 4
3(8) + 4(4) - 16/2 = 24 + 16 - 8 = 40 - 8 = 32
How many terms are shown? 8x + 6y - 3
3
Evaluate. 4n + 3 when n is 11
4 (11) + 3 = 44 + 3 = 47
Write the expression. "The difference of 8 and n divided by 2"
(8-n) / 2
Write the expression. "The product of 4 and n decreased by 9"
4n - 9
What is the coefficent of x? 8xy + 7y - 5x + 8
5
Write the expression. 11 more than h
11 + h OR h + 11
