Gus has skydived 4 more times then nico. if they both skydived a total of 20 times, how many times has gus skydived?

12

Step-by-step explanation:

If they have both skydive a total of 20 times it would look like this

10/10

But the question tells us gus has skydives 4 more times so we balance the ratio

9/11

And again

8/12

And we know that gus has skydives more so the answer is 12

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
