7/15 multiplied by 5/14

Answers

so to solve this we multiply the numerator with the numerator and the denominator with the denominator 
 7       5
---- = ----
15     14
so thats 7×5 and 15×14 
the answer from the numerators →      35
                                                           -------
the answer from the denominators→  210

now find the GCF of the fraction which is 7 and divide both the top and bottom with it so 35÷7 and 210÷7 
answer from numerator →     5
                                              ---
answer from denominator→ 30
but this can be simplified further with a GCF of 5 

answer with new GCF is 1/6
hope this helps

What is the result when 4x^2-17x+36 is subtracted from 2 x^2-5x+25?

Answers

2x^2-5x+25-(4x^2-17x+36)=\n 2x^2-5x+25-4x^2+17x-36=\n -2x^2+12x-11
2x^(2) - 5x + 25 - (4 x^(2) - 17x + 36) = 2x^(2) - 5x + 25 -4 x^(2) +17x -36 = (2-4) x^(2) + (-5+17)x + 25 - 36 = -2 x^(2) + 12x - 11

4m + 5n = 25 solve for N

Answers

Isolate n.

First subtract 4m.
5n = 25 - 4m

Divide by 5 to get n by itself.
n = 5 - 4/5m

That's your final answer.

Add -4m to both sides

4m+5n -4m = 25-4m

5n = -4m +25

Divide both sides by 5

5n/5 = -4m+25/5

n = -4/5 m +5


I hope that's help ! If you have questions please let me know


n = -4/5
