a store is having a sale on trail mix and jelly beans. For 5 pounds of trail mix and 6 pounds of jelly beans, the total cost is $23. For 3 pounds of trail kix and 2 pounds of jelly beans, the total cost is $11. Find the cost for each pound of traol mix and each pound of jelly beans

j=$1.75/lb

t=$2.5/lb

Step-by-step explanation:

(1) 5t+6j=23

(2) 3t+2j=11, t=11/3 - 2j/3

sub t into (1):

5(11/3 - 2j/3) +6j = 23

55/3 -10j/3 +6j =23

8j/3=14/3

8j=14

j=7/4

sub j into t:

t=11/3 -2(7/4)/3

t=5/2

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
