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
3/4 is 0.75.
3/4 is larger than 0.7
Answer:
13x-10y
Step-by-step explanation:
Combine like terms;
10x+3x = 13x
-8y-2y = -10y
So it would give the equation of 13x-10y
Answer:
f(g(- 2)) = 5
Step-by-step explanation:
Evaluate g(- 2) then use this result to evaluate f(x)
g(- 2) = (- 2)² - 5 = 4 - 5 = - 1, then
f(- 1) = - (- 1) + 4 = 1 + 4 = 5
