Answer:
5 and 1/3 cups of water.
Step-by-step explanation:
Set up a proportion like this:
2:3 for the original recipe
Then a second proportion for the recipe Jacoby used:
w:8 (use w for the unknown water amount)
Set up an equation so that the proportions equal each other. It helps if you write them in fraction form:
Use cross multiplication to get the new equation:
8 x 2 (or 16) = 3w
Then, divide both sides by 3 to get the amount for w, or water, by itself:
5 and 1/3 = w
I hope this helps! ☺
Answer: 20/12
Step-by-step explanation: In order to get a 12 in the denominator
of 5/3, we multiply top and bottom of 5/3 by 4 to get 20/12.
So 20/12 is an equivalent fraction.
750 kilometers. 21 divided by 7 is 3. If 7 cm equals 250 km, then 7 × 3 = 250.
<u>Answer-</u>
<u>Solution-</u>
Here, n represents the number of months and f(n) represents the number of laptops in the store after n months.
As the store had 150 laptops in the month of January or at the beginning.
So
Every month, 20% of the laptops were sold and 10 new laptops were stocked in the store.
As 20% of laptops were sold, so 80% were in the store.
So, after one month total number of laptops in the store,
Again after one month total number of laptops in the store,
Analyzing the pattern, the recursive function f(n) will be,
