Answer:
Ok so first you would have to turn them into improper fractions which is
3 
= 
and 4 
= 
So now that you have made them both improper fractions you have to find common denominators.
To find common denominators you must multiply both the numerator and the denominator by the same thing. Since your oposing fraction has a denominator of 5 you can know that a even number wont go in an odd number so take and mutiply both numbers by 2 and get 
. Then mutiply both numbers in by 5 to get a common denominator.
=35 - 44 = -9 so your answer is 
Step-by-step explanation:
the starting amount would be the 550, because it doesn't have a variable assigned to it.
change per week is 20 since it is being multiplied by the number of weeks
When two triangles are congruent they<span> will </span>have<span> exactly the </span>same <span>three sides and exactly the </span>same<span> three angles. The equal sides and angles may not be in the </span>same<span> position (</span>if<span> there is a turn or a flip), but </span>they<span> are there.</span>
