Something like physics, you want to not have such a specific major because you can always change your mind later on. It might take around 10ish years, but that is a rough estimate.
Answer:
4 and 15
Step-by-step explanation:
Let the two numbers be a and b.
The sum of the two is 19. Therefore:
One number (let's use a) is 7 <em>more</em> than twice the other. Thus:
Solve for the system of equations. Substitute the second equation into the first:
Subtract 7 from both sides:
Combine like terms:
Divide by 3:
So, b is 4.
And since they add up to 19, this means that a is:
So our numbers are 4 and 15
And we are done :)
They are = because both can be reduced to 9/17
Also their cross products are equal 27 x 34 = 18 x 51 - Both equal 918 so both fractions are equal to each other.
