Make x the subject of m=n+x/p?

I am assuming m=n+(x/p) 1)first me substract both side by 'n' m-n=x/p 2)then we multiply both sides by 'p' (m-n)*p=x hence this is the final answer x=(m-n)*p

Express as a product of Prime factor 24?

Prime factors means prime numbers Let’s list the first 5 prime numbers 2, 3, 5, 7, 11 9 is not a prime number because it belongs to the 3 times tables as well as itself and 1. Now 24 —> 2 x 12 2 is lowest prime so leave that, focus on 12 24 —> 2 x 12 —> 2 x 2 x 6 Leave the 2’s focus on the 6 24 —> 2 x 12 —> 2 x 2 x 6 —> 2 x 2 x 2 x 3 Now they are all prime Final Answer: 24 = 2 x 2 x 2 x 3 = (2^3)... more

What’s the nth term of 1,10,25,46,73,106?

This is a quadratic sequence. 1) Find the difference between each term: difference between: 1 and 10 = 9 10 and 25 = 15 25 and 46 = 21 46 and 73 = 27 73 and 106 = 33 2) Find the common difference of the differences So 9, 15, 21, 27, 33 The common difference between these numbers is 6. You divide this by 2 and now this will be your coefficient for n^2, so 3n^2. 3) Find the values for 3n^2 f... more

5n - 30 sequence?

n represents where the term in the sequence. So for the first term n=1, for the second term n =2 etc. All you have to do is substitute in values for n to find the terms of the sequence. 5(1) - 30 = -25 5(2) - 30 = -20 5(3) - 30 = -15 5(4) - 30 = -10 5(5) - 30 = -5 5(6) - 30 = 0 So the first 6 terms for your sequence would be: -25, -20, -15, -10, -5, 0

Where are the oldest parts of the oceanic crust found?

The oldest parts of oceanic crust only reach around 200-260 million years old, which is relatively young compared to continental crust because it goes through a recycling process. New, young oceanic crust is formed at mid-ocean ridges, where seafloor spreading occurs. As the seafloor spreads over time, the crust gets colder and denser with age. The oceanic crust, thus gets to a point where it so d... more

What is the easiest way to identify the mineral calcite?

Identifying calcite is relatively easy. Firstly, it is generally light-coloured (mostly white) and is translucent to transparent. It's hardness is about a 3 on the Moh's hardness scale, so it can't be scratched by your fingernail, but scratching it with a metal nail or your hammer will leave a mark. The final step is to use the hydrochloric acid test. If it reacts with the acid and begins to bubbl... more
