Given expression: 21 + (36 + 0 + 19)
Using identity property of addition: a + 0 = a
21 + (36 + 0 + 19) = 21 + (36 + 19)
Using commutative property of addition: a + b = b + a
21 + (36 + 19) = 21 + (19 + 36)
Using associative property of addition: a + (b + c) = (a + b) + c
21 + (19 + 36) = (21 + 19) + 36
Now, add two numbers inside the bracket.
(21 + 19) + 36 = 40 + 36
Using closure property of addition: a + b = c any number.
40 + 36 = 76
Hence 21 + (36 + 0 + 19) = 76.
First of all, you will need to find the square footage of the field
that is 360*160
57,600
8 pounds of fertilizer covers 1,000 square feet
(I suppose each bag is 8 pounds)
to see how many square feet each bag covers 1,000/8
each bag covers 125 square feet
to see how many bags you need, you divide the square footage of the field by how many square feet each bag covers
57,600 / 125
that is 460.8 pounds of fertilizer
460.8 / 50 is 9.216 bags of fertilizer
Hope this helps :)
Hopefully this was good enough
The slope would be 0 because if you put in the coordinates with the formula, you would get the slope as 0. This also makes sense because both points have the same y point, so that means that the line wasn’t travelling up or down. And since it was only going through -8 that would be the y-intercept.
Okee dokee, 9/10*3 1/3, so first, you need to change 3 1/3 from a mixed number to a fraction, which is 10/3, then all the steps is below:
9/10*10/3 => 9*10/10*3 => 90/30 => 3
The correct answer is 3.
