Step-by-step explanation:
Isolate y in the first inequality:
Now, with both x and y inequalities found, graph it.
Hailey's mixing two different coffee blends. Represent them by x and y (in pounds). Then x + y = 5 lb, and x = 5 - y.How much puree Sum. beans are we talking about here?
0.20x +0.80y = 0.60(5 lb) Mult all 3 terms by 100 to get rid of factions:
20x + 80 y = 300. Substitute 5-y for x:
20(5-y) + 80y = 300 => 100-20y + 80y = 300 => 60y = 200, so y = 20/6 or 10/3 lb den x = 5-10/3, or x =5/3 lb
Use 5/3 lb of the first blend and 10/3 lb of the second blend to come up with 5 lb of a 60% blend.

Answer:5m
Step-by-step explanation:
3m +m+m=5m not 3m +2
In a right triangle with 45 degree angles the two sides are the same length. The hypotenuse is the length of the sides x sqrt(2)
The length of x = 3 and y = 3
