It’s often difficult to know which method (graphing, substitution, or linear combination) is best to use when solving a system of equations. Certain methods work much more smoothly with certain systems than others. Knowing when to use each method is a useful skill for algebra. Design a chart, flow chart, mind map, or some other visual to help you decide when to use each solution method.

the solution is 12x-6y

answer: 800

step-by-step explanation:

the answer is

d.

5.3066 m2

step-by-step explanation:

45.36 feet per second.

step-by-step explanation:

to find the most accurate determination for the number of feet per second tyrone traveled on his way to work let us convert miles to feet and minutes to seconds.

1 mile = 5280 feet.

1 minute = 60 seconds.

now we will divide 158400 by 3492 to find the most accurate determination for the number of feet per second tyrone traveled on his way to work.

therefore, tyrone traveled on his way to work at the rate of 45.36 feet per second.
