You have to pull apart 16 and 28 so you have their end prime factors
Which are:

16: 2 2 2 2
28: 2 7 2

If the same factor occurs more than once in both numbers, you multiply the factor with the greatest number of times it occurs multiply them to 7 to get the lcm with prime factorisation

2x2x2x2x7 =112
❤️❤️ if this doesn’t make sense message me I really don’t mind

The lease common denominator using prime factorization would be 2. 2 is the number they can both be divided by and is also a prime number

This is not a full question.  If you were given the amount at the begining of 1970 (we'll call it x) and the amount at the end of 1980 (we'll call it y), we should solve them accordingly:
y-x=? (calling the answer a)
a/y=%(not answer yet, call this b)

What is the result of adding these two equation?<br> 5x-9y=1<br> -7x+2y=-5
SCORPION-xisa [38]

The result of adding the given equations is 2x+7y=4.

Step-by-step explanation:

Given equations are;

5x-9y=1     Eqn 1

-7x+2y=-5   Eqn 2

Adding Eqn 1 and 2

(5x-9y)+(-7x+2y)=1+(-5)\\5x-9y-7x+2y=1-5

Arranging alike terms;

5x-7x-9y+2y=-4\\-2x-7y=-4

Dividing each term by -1

\frac{-2x}{-1}+\frac{-7y}{-1}=\frac{-4}{-1}\\2x+7y=4

The result of adding the given equations is 2x+7y=4.

<u>Step 1:  Subtract 15 from both sides</u>

<u />6x^2 - x - 15 = 15 - 15

6x^2 - x - 15

<u>Step 2:  Factor</u>

6x^2 - x - 15

(2x + 3)(3x - 5)

Answer:  (2x + 3)(3x - 5)
