Let's solve each question step by step.
Question 10: Solve: 35 ÷ (-5) =
- 35 ÷ (-5) = -7
- So the answer is -7.
Question 11: Solve: 364 ÷ (−7) =
- 364 ÷ (-7) = -52
- So the answer is -52.
Question 12: Which of the following expressions has the same quotient as -49 ÷ (-7)
Let's solve the given expression:
- -49 ÷ (-7) = 7 (Dividing a negative by a negative gives a positive result)
Now let's check the options:
- 35 ÷ (-5) = -7
- -21 ÷ 3 = -7
- -70 ÷ (-10) = 7
- 56 ÷ (-8) = -7
Thus, the expression that has the same quotient (7) is -70 ÷ (-10).
Question 13: Mikayla withdraws $20 from her account on 4 different days during the week. At the end of the week, what is the total change in her account balance after the withdrawals?
- Total withdrawal = 4 days × $20/day = $80
- So the total change is - $80.
Question 14: Joey got his paycheck of $1,200 at the beginning of the month. He paid his phone bill of $95. He bought groceries for $48. Then he received a work bonus of $500. How much money does Joey have now?
- Starting balance = $1,200
- Expenses = $95 + $48 = $143
- After expenses: $1,200 - $143 = $1,057
- Final balance after bonus = $1,057 + $500 = $1,557
So, Joey has $1,557.
To summarize:
- -7
- -52
- -70 ÷ (-10)
-
- $80
- $1,557
