Jimmy and john are trying to put a mixture together of blue jelly beans and red jelly beans for a souvenir. gift. the blue jelly beans cost $0.28 per ounce and the red jelly beans cost $0.55 per ounce. they would like their. gift bags to cost $2.20 per bag. use complete sentences to explain why or why not it would be reasonable to say that the mixture could contain 4 ounces of blue jelly beans and 3 ounces of red jelly beans.

It is not reasonable for Jimmy and John to say that the mixture has 4 ounces of blue jelly beans and 3 ounces of red jelly beans because it would cost them $2.77 per bag instead of $2.20 per bag. If they were to put 4 ounces of blue jelly beans and 3 ounces of red jelly beans, they would be going over budget.

please rate and thank : )

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
