You have enough fingers and toes to figure this one out (unless you are a redneck which might explain the question in the first place). The answer should also be memorized: 15. Please don't make a mockery of the calculus section.
7 × (r + 8) = 7(r + 8) = 7r + 56
To determine how many times 8 goes into 63, you would perform long division. When you divide 63 by 8, you get 7 with a remainder of 7. This means that 8 goes into 63 a total of 7 times, with a remainder of 7.
The total is 8(1/4 + 3/4 = 1 + 7 = 8 )
7 columns * 8 rows = 56 units
7 quadrilaterals = 7 x 4 = 28 sides 8 hexagons = 8 x 6 = 48 sides Total is 76 sides
Eight goes into 56 a total of 7 times. This can be calculated by dividing 56 by 8, which equals 7. Thus, 8 multiplied by 7 equals 56.
From 7 AM to 3 PM is a total of 8 hours. This is calculated by counting the hours from 7 AM to 8 AM (1 hour), then from 8 AM to 3 PM (7 hours), which totals 8 hours altogether.
From 7 PM to 8 AM is a total of 13 hours. This includes the 5 hours from 7 PM to midnight and the 8 hours from midnight to 8 AM.
