Answer:
3 bags of chocolate chips
Step-by-step explanation:
72 cookies is equal to 6 dozen cookies. 18÷6 = 3. So, we have to multiply the 1 bag of chocolate chips by 3 to get the total amount of chocolate chips. 1×3=3 so it takes 3 bags of chocolate chips to make 18 dozen cookies.
<span>6 km × 1 hour/(b-4 km) = 12 km × (1 hour/(b+4 km)
6/(b-4) hours = 12/(b+4) hours
6(b+4) = 12(b-4)
6b + 24 = 12b - 48
72 = 6b
b = 12
The boat's speed in still water is 12 km/hour.</span>
Answer: 16 gallons
Step-by-step explanation:
Since we are given the information that 1/4 of the gas is left, it simply means that (1 - 1/4) = 3/4 has been used.
The tank was filled and this was 12 gallons of gas.
Let the gas that the tank hold be represented by x. Therefore,
3/4 of x = 12
3/4 × x = 12
0.75x = 12
x = 12/0.75
x = 16
The tank holds 16 gallons of gas.
