Answer:5 people were in each car.
Step-by-step explanation:
Let x represent the number of people that travelled in each car.
The total number of people in the Bailey family that made the trip to the drive-in movie theater was 42.
Seven cars filled and 7 more people traveled in a truck. This means that
7x + 7 = 42
Subtracting 7 from the left hand side and the right hand side of the equation. It becomes
7x + 7 - 7 = 42 - 7
7x = 35
Dividing the left hand side and the right hand side of the equation by 7, it becomes
7x/7 = 35/7
x = 5
I think you meant "evaluate the given equation."
<span>3x – y = 1 becomes 3x-1=y. Then: 3(-1)-1 = y = -4 when x=-1.
The y-values for {0, 1, 3} are {-1, 2, 8}</span>
Answer:
3/10 of a bone per day
Step-by-step explanation:
Take the number of bones and divide by the number of days
1 4/5 ÷ 6
Change to an improper fraction
9/5 ÷6
Copy dot flip
9/5 * 1/6
Rewriting
9/6 *1/5
Simplifying the first fraction
3/2 *1/5
3/10
3/10 of a bone per day
