First, make sure that there is a common denominator, or in other words, the denominators, are the same.
You have the numbers 15 and 5 and the lowest common multiple between the two is 15, and in order to make sure the denominators are both the same, you multiply 5 by 3.
Now, whatever you do to the bottom, you make sure you do to the top. In other words, multiply the numerator by 3 as well, and the second fraction is now 3/15. You can now subtract 3 from 13 and the answer is 10/15. You can reduce that to 2/3 by factoring out a 5.
13/15 - 1/5 --> 13/15 - 3/15 = 10/15 --> 2/3
This is a picture of my work. Hope it is easy to understand.
Answer:
8 = 3x - 4y
or y = (3/4)x - 2
Step-by-step explanation:
(4,1) and (0, -2) are the two points I see.
slope = (1 -(-2))/(4 - 0) = 3/4
y-int: -2
y = (3/4)x - 2
or 2 = (3/4)x - y
8 = 3x - 4y
Answer:
add the variables base
Step-by-step explanation:
for example 5x+3x=8x because you would add the base
Multiply the numerators together and keep the denominator.
Your answer will be 69/10.
