Answer: 0.475 cups of broth per serving.Explanation:1) Ratio given: i) To facilitate the operations, transform the mixed number 4 3/4 cups into improper fraction:
4 + 3/4 = [16 + 3] / 4 = 19 / 4
ii) ratio broth: servings
2) Proportion with the unknown number of cups of broth per serving:
3) Solve for the unknown:x = [19 / 4] cups × 1 serving / 10 servings = 19 / 40 cups = 0.475 cups
Are you rounding to the nearest 100’s place?
First, multiply the second equation by 4 so that 8y can cancel out. Now you have
5x+8y=-29
and
28x-8y=-268
Add these equations to get
33x=-297
Divide both sides by 33, and you have
x=-9
Now, simply solve for y by plugging it into an equation, and you have
y=2
The final answer is (-9,2)!
