1)7 ÷ xNone of these — It is not clear what ÷ means between 7 and x.
2)a + b – c Expression — It is an expression since it means to add b to a and to subtract c from that sum.
3)24 = 3a + 9bEquation — Here we have two expressions set equal to one another. Note that one of those expressions is an integer.
4)3x Term — This is a product of a constant and variable.
5)24x2y + 5z = 12acEquation — Here we have two expressions set equal to one another. One of those expressions is a single term, 12ac.
6)–156xwzTerm — This is the product of a number, –156, and several variables, x, w, and z.
