The answer is 5. Work backwards: first add 7 to 9, then divide by 2, then subtract 3.
9+7=16
16/2=8
8-3=5
Cross Check:
5+3=8
8*2=16
16-7=9
Final Answer: 5
40 I am pretty sure that is the right answer

Step-by-step explanation:
Irri is traveling in a group of 8 cat warriors. Each cat needs 4 liters of milk per day to maintain good morale.
The total number of liters for the cat is calculated as:
8 × 4 liters of milk
= 32 liters of milk.
Another cat has enough milk to last for 2days.
= 4 liters of milk × 2 days
= 8 liters
Mirri has a supply of 96 liters of milk.
Total liters of milk = 96 liters + 8 liters
= 104 liters
Which equation can we use to find the total number of days the milk will last?
This is calculated as:
= 104 liters/32 liters
= 3.25 days
Answer:
Step-by-step explanation:
The correct question is
Susan works as a tutor for $10 and hour, and as a waitress for $11 an hour. This month, she worked a combined total of 90 hours at her two jobs. Let t be the number of hours Susan worked as a tutor this month. Write an expression for the combined total dollar amount she earned this month
Let
t -----> the number of hours that Susan work as a tutor
y ----> the number of hours that Susan work as a waitress
z ---> the combined total dollar amount she earned this month
we know that
-----> equation A
we know that
The combined total dollar amount she earned this month is equal to the number of hours that Susan work as a tutor multiplied by $10 plus the number of hours that Susan work as a waitress multiplied by $11
----> equation B
substitute equation A in equation B
therefore
The expression for the combined total dollar amount is $(990-t)
