Solve the system by the method of elimination.

(10, -5)

Step-by-step explanation:

Given system of equations is,

0.6x - 0.3y = 7.5

Divide this equation by 0.3

2x - y = 25 (1)

0.4x + 0.2y = 3

2x + y = 15 (2)

Now we subtract equation (2) from equation (1),

(2x - y) - (2x + y) = 25 - 15

-2y = 10

y = -5

From equation (1),

2x - (-5) = 25

2x + 5 = 25

2x = 20

x = 10

Therefore, (10, -5) will be the solution of the system of equations.

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
