Answer:
1. 2
2. 3
3. 7
4. 2
5. 30
6. 18
Step-by-step explanation:
You can use proportional reasoning to answer this question.
Set up a ratio with how far she traveled in the first 2 1/3 mins. Make is equal to x feet in 8 minutes. Solve using cross products.
<u>1r feet </u> <u> x feet</u>
2 1/3 min = 8 mins
<u>8r feet</u> = <u>2 1/3 x</u>
2 1/3 2 1/3
3 3/7r feet = x
In 8 minutes, Maggie descended 3 3/7r feet.
Let us suppose a system of two equations with two unknowns.
Suppose further that the system of equations is linearly independent.
When the system of equations has a variable that has exactly the same coefficient in both equations, then the most effective method to solve the system of equations is subtracting.
This is because we eliminate one of the variables and reduce the system to an equation with one unknown.
Answer:
a system of equations in which subtraction would be the most efficient way of solving the system is:
A system of equations in which one of the variables has exactly the same coefficient in both equations.
