True or False: 5 less than n =
Write an expression for five less than the product of a number n and 8
True or False: n is an algebraic expression
Write an algebraic expression for: the quotient of the product of two and n and m
Write a word expression for this:
The FIRST step in evaluating an algebraic expression is called the _____________step
Evaluate when n = -3: 3n – (-7)
Evaluate when n = -3 and r = -2: (nr) 2
Evaluate when n = -2 : (n – 3)(n – 4) ÷ (-3n)
Evaluate when n = -4 and p = 2: (3n np) n + 2p
We solve equations by using these operations
n + (-7) = 8 What do you do to solve this?
-4n = -12
a – (-9) = -4 What do you do to solve this?
Tell 3 things you could do to both sides of this equation to solve it: -x = 8
– 3 + 2j = 4 What is the “wrapping paper”?
-2b – 3 = -19 Solve
-8 – 3x= -17 Solve
1.2k – 6 = 6 Solve
2(-3p + 6) = -18 Solve (hint: it’s 3 steps!)
In most word problems “of” means what operation?
Write an equation: 4 less than twice a number n is 6
Write an equation: Two-thirds of a number n, decreased by 3, is 12
Write an equation then solve it: The quotient of a number n and -8, less 5, is 25
Write an equation then solve: Jim is 2 years less than twice his sister’s age. If Jim is 12 how old is his sister?
