Answer 1

z = 70

Explanation:

Explanation: To solve this proportion for z, we can use cross products.

When we get the equation 5z = 350, we can get z by itself on the left side of the equation by dividing both sides of the equation by 5. On the left, the 5's cancel each other out and we have z. On the right, 350 divided by 5 simplifies to 70 so we have z = 70.
