Answer:
C. 6×11/6
Step-by-step explanation:
Because 11/6 is greater than 1, if you were to multiply it by 6, you would get a product greater than 6.
Answer:
x = 5 and y = 3
Step-by-step explanation
y crosses out so you are left with
4x = 20 (divide by 4)
x = 5
plug x into either equation
5 + y = 8 (subtract 5)
y = 3
If there are 15 boards there are 14 gaps in-between.
But first, 15 boards each 9 and 1/4th inches so you get a total of 138 inches and 3/4th
If you subtract that from 144 you get 5 inches and 1/4th. The remaining amount is the total of all of the distance from the spacing.
Then you divide that by 14 (number of gaps/spacing in-between.)
So you get .375 inches. (3/8)
So width of the spacing between each board is 3/8ths of a inch
