Me i really need it : ( > will mark brainliest< -- i already have the answer for part a, i just need part b answered and can you explain how you got your answer thx : d) delaney would like to make a 5 lb nut mixture that is 60% peanuts and 40% almonds. she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds. let p represent the number of pounds of peanuts needed to make the new mixture, and let m represent the number of pounds of the 80% almond-20% peanut mixture. (a) what is the system that models this situation? (b) which of the following is a solution to the system: 2 lb peanuts and 3 lb mixture (2,3) ; 2.5 lb peanuts and 2.5 lb mixture (2.5, 2.5); 4 lb peanuts and 1 lb mixture (4,1) ? show your work. me : '(

(a)

(b) correct choice is 2.5 lb peanuts and 2.5 lb mixture (2.5, 2.5);

Step-by-step explanation:

Let p represent the number of pounds of peanuts needed to make the new mixture, and let m represent the number of pounds of the 80% almond-20% peanut mixture.

1. In m pounds of the 80% almond-20% peanut mixture there are 0.8m pounds of almonds and 0.2m pounds of peanuts.

2. When added p pounds of peanuts to m pounds of mixture, you get (p+0.2m) pounds of peanuts and 0.8m pounds of almonds.

3. In 5 pounds of the 40% almond-60% peanut mixture there are pounds of peanut and pounds of almonds.

(a) Then you get a system of two equations:

(b) Solve this system. From the first equation

then

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
