Answer:
15
Step-by-step explanation:
let r represent red marbles then white = 2r + 5 and total is 20, thus
r + 2r + 5 = 20 ( subtract 5 from both sides )
3r = 15 ( divide both sides by 3 )
r = 5 ← number of red marbles
Thus number of white = 20 - 5 = 15
Answer:
y has the greatest value.
Step-by-step explanation:
1.23w = t
Divide both sides by 1.23.
--- (1)
1.01x = t
Divide both sides by 1.01.
--- (2)
0.99y = t
Divide both sides by 0.99.
--- (3)
From (1), (2) and (3), it is clear that y has the greatest value.

Answer: The width of the leftover brass is 17 inches.
Step-by-step explanation:
Hi, to answer this question, first, we have to add the width of the pieces cut.
Mathematically speaking:
8 in +8 in = 16 in
Now, we have to subtract that result to the width of the sheet of brass.
33 in -16 in = 17 in
The width of the leftover brass is 17 inches.
