Question 1
3y; y+y+y
3y = 3 (2) = 6
y+y+y = 2+2+2 = 6
anwser: They are both 6.
Question 3
2z+3z
answer: 5z
part 2
2z+3z
Evaluate the expression when z=7.
2 (7) + 3 (7) = 14 + 21 = 35
Question 4
Consider the expressions 6x and 3 (x+2).
Evaluate each expression for x=2.
6x = 6 (2) = 12
3 (x+2) = 3 (2+2) = 3*4=12
answer:
The expressions are not equivalent, but the answers are the same when x=2.
Question 7
Select all the statements that are true.
_F__ 116b is equivalent to 16b.
_F__ 14b+13b is equivalent to 27b.
__F_ 13 (b+7) is equivalent to 13b+73.
_T__ b+0.3+4b is equivalent to 5b+0.3.
Question 8
Select all the statements that explain why 7x+2x and 4x+5x both equal 18 when x=2.
7x+2x = 7 (2) + 2 (2) = 14 + 4 = 18 ... (9x)
and
4x+5x 4 (2) + 5 (2) = 8+10 = 18 ... (9x)
Answer:
___ Both expressions simplify to 9x when like terms are combined.
___ The expressions are equivalent, because when you combine like terms in each, the result is the same.
Question 10
Consider the expressions 2 (x+2) and 2x+2.
Evaluate each expression for x=4.
2 (x+2) = 2 (4+2) = 12 ... (2x+4)
2x+2 = 2 (4) + 2 = 10 ... (2x+2)
