Zepler [3.9K]

Answer:

5 milk shakes

Step-by-step explanation:

From the above question, we know that for the recipe

1/3 cup of milk = 1 milk shake

15/8 cup of milk = y milk shakes

We cross Multiply

15/8 cup × 1 = 1/3cup × y

y = 15/8 cup × 1 /1/3cup

= 15/8 ÷ 1/3

= 15/8 × 3

= 45/8

= 5.625 of 5 5/8 cups of milk

Therefore, the maximum number of

milkshakes the server can make following the recipe porpotians is 5 milk shakes.

Sean is driving to visit his friend in another state. In the first hour, he travels 1/5 of the total distance. Second hour he tr
astra-53 [7]

Answer:

The friends live 285 miles apart.

Step-by-step explanation:

Let total distance in miles Sean needs to cover to visit his friend be = x

On first hour distance traveled in miles is = \frac{1}{5}\ of\ the\ total\ distance = \frac{1}{5}.(x)=\frac{1}{5}x

Distance left to cover  after first hour = x-\frac{1}{5}x

On second hour distance traveled = 34 miles

Distance to still left to be covered = 194 miles

Total distance to be covered after first hour will be = 34\ miles+194\ miles = 228 miles

Thus, the equation can be given as:

⇒ x-\frac{1}{5}x=228

Multiplying each term with 5 to remove fractions.

⇒ 5x-5.\frac{1}{5}x=5\times228

⇒ 5x-x=5\times228

⇒ 4x=1140

Dividing both sides by 4.

⇒ \frac{4x}{4}=\frac{1140}{4}

∴ x=285

Thus, the friends live 285 miles apart.
