Solve the problem by setting an equation.
To manage a purifier, three companies intervene. The cost of the works is 48,000 euros, to be divided into three companies: the Rossi company, the Verdi company and the Viola company. The share of the Viola company is three times that of the Rossi company, while the share of the Verdi company is four times that of the Rossi company. What is the share of the three companies?

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

37 = ending with 7

unit's digit in the cube..3

56 = ending with 6

unit's digit in the cube..2

133 = ending with

unit's digit in the cube..7
