A store is having a sale on almonds and jelly beans. For 4 pounds of almonds and 8 pounds of jelly beans, the total cost is $25. For 2 pounds of almonds and 3 pounds of jelly beans, the total cost is $10. Find the cost for each pound of almonds and each pound of jelly beans.

let x = number of pounds of jelly beans

    y = number of pounds of almonds .

then , 4x + 8y =33

          2x + 3y = 13

multiply the second equation by -2 to get the system :

4x + 8y =33

-4x - 6y = -26

adding the equations ,we get 2y=7. so y=3.5

substitute for y in either of the given equations : 2x + 3 (3.5) =13

+ 10.5=13

     2x =2.5

        x=1.25

answer : A pound of jelly beans costs $1.25 and a pound of almonds costs $3.50.

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
