Answer:
The boiling point of water is between 84 °C and 88 °C when the elevation is between 3.4 and 4.6 km.
Step-by-step explanation:
You want x such that ...
84 ≤ B(x) ≤ 88
84 ≤ 100 -3.5x ≤ 88 . . . . substitute for B(x)
-16 ≤ -3.5x ≤ -12 . . . . . . . .subtract 100
4.6 ≥ x ≥ 3.4 . . . . . . . . . . .divide by -3.5; this reverses the inequality

Answer:
y < 6/4x - 3
Step-by-step explanation:
Answer:
7/4 or 1.75 drops
Step-by-step explanation:
In one gallon there are 128 ounces, if it takes 28 drops of coloring to turn 128 ounces of milk green then:
28/128
7/32
it takes 7/32 drops of food coloring to turn one ounce of milk green.
for 8 ounces, you multiply it by 8:
8*7/32
7/4≈1.75
∴ It would take 1.75 or 7/4 drops of coloring to turn 8 ounces of milk green.
