Haley would like to make a 5-pound coffee mixture that is 60% sumatra coffee bean blend. she has several pounds of a mixture that is 20% sumatra beans and another mixture blend with 80% sumatra beans. let x represent the amount of the 20% blend and y represent the amount of the 80% blend to find out how many pounds of each mixture hailey will need. what is the system that models this situation? what is the solution to the system: show your work.

x

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

hi there!

question 1 answer: p/q can be terminating when q = 5^m * 2^n

question 2 answer: -1 and -1

question 3 answer: -4

question 4 answer: 5/12

hope this : )
