<span><span>−<span>4.9x</span></span>+1.3</span>><span>11.1
subtract 1.3 from both sides
</span><span>−<span>4.9x</span></span>><span>9.8
</span>divide both sides by -4.9
x<-2
198 = 5X:X = A:B
198 = 5X + X = 6X
X = 198 / 6 = 33
A = 33*5 = 165mph
B = 33*1 = 33mph

Answer: 4 gallons require 5 5/39 spoons of syrup
Step-by-step explanation:
Given it takes 3 2/6 spoons to make 2 3/5 gallons of chocolate milk
i.e. 20/6 spoons make up 13/5 gallons of milk
⇒1 gallon require 20/6/13/5 spoons of milk
⇒ 20 x 5/6 x 13 spoons of milk
⇒ 100/78 spoons of milk
Therefore 4 gallons require 4 x 100/78 spoons
⇒ 400/78 spoons
⇒ 200/39 spoons
⇒ 5 5/39 spoons
10^-5 = 0.00001
27 divided by 0.0001=2700000
