Answer:
The measure of angle x is 
Step-by-step explanation:
To find the measure of angle X, apply the law of cosines
The law of cosines states that
In this problem we have
substitute
![C=arccos[(986-576)/950]=64.4\°](https://tex.z-dn.net/?f=C%3Darccos%5B%28986-576%29%2F950%5D%3D64.4%5C%C2%B0)
Therefore
The measure of angle x is
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:
x=9
Step-by-step explanation:
5x+12=3+6x
Subtract 5x on both sides to get the variable on the same side of the equation
12=3+x
Subtract 3 on both sides to isolate the variable
9=x
