Answer:
a) = 17 cups b) = 19
Step-by-step explanation:
a). You need to use the equation for this. Since W is what we are trying to find just plug in the values. Therefore it should be...
1.5x11 + .5 = 17
b). You need to work backwards from your formula. Since we know W, the formula will look like...
29=1.5r+.5
- So for this problem, I would suggest the guess and check method. Knowing 11 cups of rice equals 17 cups of water, we should pick a number higher than 11.
- For example, lets use the answer to make this simpler, therefore we pick 19. Next, we fill in the formula; we should get...
29=1.5x19+.5
- As one can see, the answer is 19 because using the formula we end up with 29 cups of water.
- Hope this helped! If you need a further explanation or more help please let me know, as I would be glad to help anytime.
