Answer:
I will put this into fractions for you- I hope you meant that
Step-by-step explanation:
15x turns into 30/2x
-4y turns into -8/2x
And finally 18 turns into 36/2
So the whole equation looks like this-
30/2x-8/2x=36/2
P.S. I just multiplied everything by 2 and put 2 as the denominator
The denominator is in the bottom of a fraction bar while the numerator is on the top.
Answer:
12. 6.4
13. 20
Step-by-step explanation:
This is the Pythagorean theorem, which says a^2+b^2=c^2. So for problem 12 we have 4^2+5^2=c^2. Since, 16+25=41, c=sqrt41 which is about 6.4. For problem 13 we have 15^2+b^2=25^2. Since 25^2-15^2=400, b=sqrt400 which is 20. Hope this helps!
Answer: x = 9
Step-by-step explanation:
1) Combine multiplied terms into a single fraction
2) Find a common denominator
3) Combine fractions with common denominator
4) Multiply from left to right (PEMDAS)
5) Multiply all terms by the same value to eliminate fraction denominators
6) Cancel multiplied terms that are in the denominator
7) Multiply again
8) Add _ to both sides
9) Divide both sides by the same factor getting 125x/125 = 1125/125
10) Simplify, x = 9
Their angles/lengths (depending on which type of graph you are using) would be the same.
