Answer:
Step-by-step explanation:
You start with creating let statements.
Let x = the cost of each pencil.
Let y = the cost of each eraser.
Let z= the cost of each pen.
Then, you’d fill in information from the problem.
3x + 4y = 65
2z + y = 35
Now, you’d solve like a system of equations; meaning you can do elimination or substitution.
Answer:
8.6
Step-by-step explanation:
Use the distance formula to find the distance between the two points.
√[(x₂ - x₁)² + (y₂ - y₁)²]
√[(3 - -4)² + (3 - -2)²]
√[(7)² + (5)²]
√[(49) + (25)]
√74
8.6
20x + 5y = 15
Subtract 20x on both sides
5y = 15 - 20x
Divide by 5 on both sides
y = 3 - 4x
It is C , Mitchell’s data and Luke’s data have the same interquartile range
40/16 or 2.5 meters per second.... Sorry I'm probably way too late
