Nine fourteenths of 6x, and then subtract 10
9/14 x 6x - 10
2p + 8p + 3p
13p
Describe the expression as a monomial or binomial. If the expression is a monomial, state its degree if needed.
4x2 - y
binomial
9p + 5 = 213
p = -2
9x + 4 > 5x - 8
x < -3
Subtract 20 from 15/23 b
15/23 b – 20

Describe the expression as a monomial or binomial. If the expression is a monomial, state its degree.
82n + 5n + 5n2
Trinomial
5.7 - 0.3y = 6.9
y = 4
11 + x < 7 + 5x
the sum of 5r and 7, divided by 15
