I think you're right. I'm in pre-algebra, and sucks at it. Yet, I keep a A.
Well 1/40 is 0.025 so that should be the write fraction to use
Answer:
Interpreting as: 10y+11=25-3y
Input:
10 y + 11 = 25 - 3 y
Let b be the number of blue beads and g the number of green beads that Giovanni can use for a belt.
He's supposed to use a total of between 70 and 74 beads, so
70 ≤ b + g ≤ 74
The ratio of green beads to blue beads is g/b, and this ratio has to be between 1.4 and 1.6, so
1.4 ≤ g/b ≤ 1.6
For completeness, Giovanni must use at least one of either bead color, so it sort of goes without saying that this system must also include the conditions
b ≥ 0
g ≥ 0
(These conditions "go without saying" because they are implied by the others. g/b is a positive number, so either both b and g are positive, or they're both negative. But they must both be positive, because otherwise b + g would be negative. I would argue for including them, though.)
The answer is 14.27 :) correct me if wrong I think I am
