1 answer:

4 0

It's the last choice. In the top row you have the 1's that are the coefficients on the x and the y, and the solution for that equation is 21; in the second row you have the 5 from the x and the 4 from the y and the solution for that equation which is 20. I'm more used to writing them down instead of across, but there you have it anyways

natka813 [3]

Given:

About 3/5th of the registered voters participated in 2016 election.

California has 25 million registered voters.

To find:

The number of registered voters who participated in 2016 election.

Solution:

We have,

Total number of registered voters = 25 million

According to the question,

$\text{Registered voters who participated}=\dfrac{3}{5}\times \text{Total number of registered voters}$

Now,

$\text{Registered voters who participated}=\dfrac{3}{5}\times 25$

$\text{Registered voters who participated}=3\times 5$

$\text{Registered voters who participated}=15$

Therefore, there are 15 millions of registered voters who participated in 2016 election.
