True or False:5 less than n =
Write an expressionfor five less than the
productof 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 expressionfor this:
The FIRST step in evaluating an algebraic expression is called the
_____________step
Evaluate when n = -3:3n – (-7)
Evaluate when n = -3and r = -2:
(nr)2
Evaluate when n = -2 :
(n – 3)(n – 4) ÷ (-3n)
Evaluate when n = -4and p = 2:
(3n + 9 - np)n + 2p
We solve equations by using these operations
n + (-7) = 8
What do you do to solve
this?
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?
