x = 9
The sides on the left are proportional and can be used to find the sides on the right.
Since 72/8=9, 56/8 must equal 3x-20
There would be 12 pieces because if you only have one foot long sandwich and cut it in to 1/3's you would have 3 pieces and just multiply 4 by 3 and you'll get 12
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:
The base of the banner is 30 centimeters.
Step-by-step explanation:
Area = base × height
Plug in the numbers:
127 1/2 = b × 4 1/4
Convert mixed fractions into improper fractions for easier calculations.
Improper fraction formula: (denominator × mixed number + numerator)/denoninator
(2 × 127 + 1)/2 = 255/2
(4 × 4 + 1)/4 = 17/4
Rewrite equation:
255/2 = b × 17/4
Isolate variable b by multiplying the reciprocal of 17/4 (which is 4/17).
1020/34 = b
Simplify.
30 = b
