Something is wrong with your question, it must be 350 pounds.
So the approach for this question would be the use of unit analysis.
1 us dollar = 0.690 pounds
350 pounds * 1 dollar / 0.690 pounds= 507.24 dollars.
to check:507.24 dollars x 0.690 pounds / 1 dollars = 350 pounds
Answer:
(- 4, - 7)
Step-by-step explanation:
given the 2 equations
2x - 3y = 13 → (1)
4x - y = - 9 → (2)
multiply all terms in (2) by - 3
- 12x + 3y = 27 → (3)
Add (1) and (3) term by term
(2x - 12x) + (- 3y + 3y) = (13 + 27)
- 10x = 40 ( divide both sides by - 10 )
x = - 4
Substitute x = - 4 in either (1) or (2) for corresponding value of y
(1) : - 8 - 3y = 13 ( add 8 to both sides )
- 3y = 21 ( divide both sides by - 3 )
y = - 7
Solution is (- 4, - 7 )
So, we have 4 cups of flour and 6 cups of sugar and we need to know how many cups of sugar per cup of flour does the recipe require. Because it is requested to know how many cups of sugar per cup of flour does the recipe require, we need to divide the amount of flour and sugar by the amount of flour, and we will know what we need to know.
4 cups of flour / 4 = 1 cup flour
6 cups of sugar / 4 = 6/4 = 3/2 = 1 1/2 cups of sugar per cup of flour is the solution
