Answer:
Step-by-step explanation:
Henry X blue
Rachel 5 blue and Y black
Jack 3 times the total of pens ( blue & black)
So
X + 5 + Y for Henry and Rachel
Jack : 3( X + 5 + Y)
Jack has 3X + 15 + 3Y.
Pens of jack 3X + 15 Blue & 3Y black.
3/3=1 and 7/8 is < 1 so 3/3 is bigger

Answer:
(Exact Answer) When all the entries above the diagonal entries are 0, the solution will not be different from when all the entries below the diagonal entries are 0. This is because in both cases, there will be one row that would be left with just one unknown element, thus giving us the solution to the other unknowns through back-substitution. For instance, in a linear system with three unknowns, x, y, and z, the traditional triangulated form will give us the value of z first; however, if the entries above the diagonal entries in the matrix are 0, then we will get the value of x first. In either case, the solution will be the same.

Answer:
960
Step-by-step explanation:
it says use 3 for pi, so you plug the values into given equation
V = 3·(4)²·20
r is 4 because it is half of 8.
Then multiply
3·16·20 = 48·20 = 960
