Use the Cross Products Property to solve x/35=2/7

x = 10

Step-by-step explanation:

Equation Solving

A common strategy to solve equations given in a rational form is to eliminate denominators.

If the equation is given in the form:

We use the cross-product property to make it linear:

cx = ab

And solve it easily by dividing by c.

We are given the equation:

Cross-multiplying the denominators:

7x = 2*35

Solving:

x = 70/7=10

x = 10

6 times

Step-by-step explanation:

If there are total of 6 marbles and 3 are pink, then you will have a one half (or 50%) chance of picking a pink marble. Because you put the marble back each time, your chance of picking a pink marble remains the same every time.

So one half of 12 is 6. You are predicted to pick a pink marble 6/12 times.
