The equation representing the minimum and maximum number of fishes which would fit into the tank is : 5 ≤ x ≤ 9
From the table given ;
- Method 2 will allow the maximum number of fish = 9
- Method 1 will allow the minimum number of fish = 5
To represent the maximum and minimum number of fish that will fit into the tank;
We could use an inequality expression to represent these range :
Let x represent the Number of fishes that would fit into the tank :
Therefore, the equation can be written thus :

Answer:
15.62
Step-by-step explanation:
The length XY is found from the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((4 -(-8))² +(-6 -4)²) = √(12² +(-10)²) = √244
d ≈ 15.62 . . . units
The length of XY is approximately 15.62 units.
Answer:
The students rented 3 small cars and 6 large cars.
Step-by-step explanation:
Since a group of college students are going to a lake house for the weekend and plan on renting small cars and large cars to make the trip, and each small car can hold 4 people and each large car can hold 6 people, and the students rented twice as many large cars as small cars, which altogether can hold 48 people, to determine the number of small cars rented, X, and the number of large cars rented, Y, the following calculation must be performed:
4X + 6Y = 48
4x4 + 6x8 = 16 + 48 = 64
4x3 + 6x6 = 12 + 36 = 48
Thus, the students rented 3 small cars and 6 large cars.
The answer is -69.67
22.5 + x = -47.47
-22.5 -22.5
x = -69.87
