I assume you're looking for n.
so, take 2n/10-3n/10=2/10. Making everything have the same denominator is always easier.
This way, you have -n/10=2/10.
n=-2.
Ok soo
-5x+x/2=9
- 4x/2=9
-(2^2-1 *x)=9
2x/2=- 9/2
x=- 9/2
x= -4 1/2
Answer:k/22 =-66
k=-1,452
Step-by-step explanation:
Answer :6x + 5y = 30
5y = 30 - 6x
y = 6 - (6/5) x
So slope = -6/5
Perpendicular line has slope 5/6 (product of the slopes is -1)
So y = 5/6 x + b
Passed through (-6, -7) so -7 = -5 + b
Sp b = -2
So y = (5/6)x - 2
Step-by-step explanation:
Well, there are 8 boys and the brother is one of them so 1 is 12.5% of 8 and out of 10 girls, there 1 is the sister and 1 out of 10 is 10%. Now we multiply the percentages to get the answer 1/80
