Answer:

the answer is A

Step-by-step explanation:

because 8 divided by 25 (all the beans) is .32

And  12 divided by  25 is .48

So if you subtract .48 by .32 then you get .16

let me know if its right

Y=3x-5 y=6x-8 show all steps and write the solution
m_a_m_a [10]

Step 1: Set the two equations equal to each other and solve for x.

3x -5 = 6x - 8

3x + (-5+5) = 6x -8 + 5

(3x - 6x) = (6x - 6x) - 3

-3x/-3  = -3/-3

x = 1

Step 2: To solve for y take one of the given equation of your choice (for the purpose of this explanation I will only do y = 3x - 5) and replace x with 1, then solve for y

y = 3(1) - 5

y = 3 - 5

y = -2

(1,-2)

Check:

-2 = 3(1) - 5 ---> - 2 = -2

-2 = 6(1) - 8 ---> -2 = -2

Hope this helped!
