Answer:
Step-by-step explanation:
1. First you must substitute x=5 into g(x), then you obtain:
2. Now, you must insert g(x) into f(x), as you can see below:
3. Finally, you must susbtitute x=5 into f(g(x)), as following:
It is true that the metric system is now known as the International System of Units.
Answer:
21, 23, 25
Step-by-step explanation:
Ok, so this one may seem a little tricky, so I'll try to explain it as best as I can. :)
So because they are consecutive odd numbers, that means they are odd numbers that are one after the other. This means each number is 2 apart from the next. So by using this, we know that there is a difference of 6 between the highest and lowest number. Now let's try and make an equation:
3o + 6 = 69
Now in order to get O by itself we have to subtract 6 from both sides:
3o = 63
Now we just have to divide by three on both sides:
o = 21
So now, we know that the lowest number is 21, but we have to add 2 to get 23, and then another 2 to get 25.
Hope this helps :)
