Question
Consider the steps to simplify the expression. What property of operation is used in Step 1?
Expression: -437
+ 7 - 347
Step 1: = -437
+ 7 + (-347
)
Step 2: = -437
+ (-347
) + 7
Step 3: = -4 + (-37
) + (-3) + (-47
) + 7
Step 4: = -4 + (-37
) + (-47
) + (-3) + 7
Step 5: = -4 + (-1) + (-3) + 7
Step 6: = -8 + 7
Step 7: = -1

Which expression is equivalent to 13+(34+23)?
The expression that is equivalent to 13 + (34 + 23) is:
13 + 34 + 23
Which expression is equivalent to 1/3+(34+23)?
The expression that is equivalent to 1/3 + (34 + 23) is:
1/3 + 57
Which expression is equivalent to 1/3+ (3/4 + 2/3)?
To simplify the expression 1/3 + (3/4 + 2/3), we need to find a common denominator and then add the fractions together.
The common denominator for 3 and 4 is 12.
1/3 can be written as 4/12 and 2/3 can be written as 8/12.
So the expression becomes:
4/12 + (3/4 + 8/12)
Now, let's simplify further:
4/12 + (9/12 + 8/12)
Combining the fractions:
4/12 + 17/12
Adding the fractions:
(4 + 17)/12
21/12
Therefore, the expression equivalent to 1/3 + (3/4 + 2/3) is 21/12.
