Equations
Find the missing value of the variable:
x + 3 = 7
x = 4
Are 3x + 1 and 2x + 2 equivalent expressions? Explain your thinking.
No. They are not equivalent expressions because they will not always give the same result for every value of the variable.
Use the distributive property to simplify:
3(2x + 4)
6x + 12
Evaluate 32.
9
The sum of x and 5.
x + 5 or 5 + x
Find the missing value of the variable:
4w = 48
w = 12
Are x and 1x equivalent expressions?
Yes they are equivalent expressions because they give the same result for every value of the variable.
Use the distributive property to simplify:
4(5x - 1)
20x - 4
Evaluate 42 - 22.
12
The product of x and 6.
6x
Find the missing value of the variable:
w/6 = 12
w = 72
Are x + x + x and 3x equivalent expressions?
They are equivalent expressions because they give the same result for every value of the variable.
Use the distributive property to simplify:
4(2x-6)
8x-24
Evaluate x3 + 5. if x = 3.
32
7 less than h.
h - 7
Find the missing value of the variable:
15y = 90
y = 6
Are 4x and 4x equivalent expressions?
No. They are not equivalent expressions because they do not give the same result for every value of the variable.
Factor this expression:
7(2-x)
14-7x
Evaluate
2w2 if w =4
32
The quotient of m and 7 minus 3
m/7 - 3
x2 = 64
x = 8
Are x3 and (x)(x)(x) equivalent expressions?
Yes. They are equivalent expressions because they give the same result for every value of the variable.
Factor this expression:
27(x + 3)
27x + 81
Evaluate
12/r2 + 20 if r=2
23
3 times the sum of x and 4.
3(x+4)
