Answer:
Step-by-step explanation:
Standard form follows 2 rules: both x and y go on the same side of the equals sign, and the constant goes on the other side; no fractions allowed.
Getting both x and y on the same side we have
-3x - 2y = 2
We don't have any fractions in there so we're good as far as that goes. Some math books do not like to lead with negatives, so if we multiply the whole equation through by a -1, we get
3x + 2y = -2
which is probably the more "acceptable" answer.
Step 1
Boiling point of mercury = 357℃
Let the boiling point of the lead be x
41/200 x=357
Step 2
41/200 x=357
41/200 x times 200/41 =357 times 200/41
x=1741.46
Step 3
The boiling point of lead is 1741.46
Result
41/200x=357
The boiling point of lead is 1741.46

Answer:
54 minutes
Step-by-step explanation:
45 minutes per 2.5 miles
45/2.5 = 18 minutes per mile
3 miles * 18 minutes = 54 minutes
