Kyle has 125 marbles. fifty of these marbles are red and the rest are other colors. what is the ratio of the number of red marbles to the total number of marbles expressed in simplest terms?

2:5

Step-by-step explanation:

The first step is to write the ratio as it is presented in the question

red marbles : total number of marbles

       50         :             125

then divide both sides by their highest common factor (25)

        2           :              5

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
