x less than 5
Write the expression
5 - x
12p when p=1/4
3
15=q/3
q=5
False, 5 is NOT a solution
4+x=12
x = 8
The inverse operation of addition is ____________
subtraction
17 less than x
Write the expression
x - 17
What are the variables in this expression? Evaluate for the values given.
3x + 2y - 2z ; x=2, y=4, z=3
8
9 = n + 3
n=12
12 is NOT a solution
n + 8=8
n=0
Is it an expression or equation? and why?
x + 4 = 8
equation
because it contains an equals sign
the product of 4 and y
Write the expression
4y
8x2; x=1/2
8/4 or 2
20x = 120
x=6
6 is a solution
20 (6) = 120
32=4n
n=8
What would the inverse operation for this equation be in order to solve it?
25/d=100
multiplication
the product of 18 and x
Write the expression
18x
12/y + 32 when y=4
12
125 = p + 24
p=99
99 is a solution
99 + 24 = 125
125 = 125
4n=120
n=30
Denise scored 3 fewer points than Carter scored. Denise scored 8 points. How many points did carter score? Write an equation and solve.
c - 3 = 8
c=11
9 less than y
Write the expression
y - 9
(6-5)25y - 42 when y=5
117
d/5=125
d=25
25 is NOT a solution
25/5=5
a solution would be 625
x/6 = 7
x = 42
