You need to multiply each term inside the bracket by 8:
8(w-4)
=8w-32
Answer:
8 laps
Step-by-step explanation:
You can simply add up the number of laps:
(1st student laps) + (2nd student laps) +(3rd student laps) +(4th student laps)
= 2 laps + 2 laps + 2 laps + 2 laps
= 8 laps . . . . total for the 4 students
__
Many people find it tedious to add the same number over and over, so they make use of the invention of multiplication. If you want to add 4 twos, you can simply multiply 4 times 2 to get the result.
total laps = (laps/student) × (number of students)
= (2 laps/student) × (4 students) = 8 laps

May people look at this and say "word problem!" and then turn off their brain and go into a state of shock.
It is more productive to read the words, and use your imagination to visualize the scenario and what the question is asking. If you imagine 4 team members standing at the starting line and anticipating running 2 laps (each), the total number of laps should be so obvious that you don't even have to think about how you arrived at the solution.
Answer:
x = 13.5
Step-by-step explanation:
direct variation
y = kx
substitute x and y to find k
8 = k*6
divide by 6
8/6 =k
4/3 = k
y = 4/3 x
now put in y =18
18 = 4/3 x
multiply by 3/4
18 * 3/4 = 3/4 * 4/3 x
54/4 = x
change to a decimal
13.5 =x
