Answer:
Note that
0.16666...is equivalent to 1/6
Step-by-step explanation:
We can use the sum of fractions to write out the decimal:
For this particular question, we can see that
0.16666...is the fraction 1/6, therefore
the given decimal
2.16666...=2+1/6=13/6
R-9s=2 add 9s to both sides
r=2+9s making 3r-3s=-10 become:
3(2+9s)-3s=-10 perform indicated multiplication on left side
6+27s-3s=-10 combine like terms on left side
6+24s=-10 subtract 6 from both sides
24s=-16 divide both sides by 24
s=-16/24
s=-2/3, making r-9s=2 become:
r-9(-2/3)=2 perform indicated multiplication on left side
r+6=2 subtract 6 from both sides
r=-4
So s= -2/3 and r= -4
Answer:
Assume as book to be x and pen to be y.
3x+2y=395 equation 1
2x+5y=355 equation 2
Make any variable either x or y to be equal.
3x*2+2y*2=395*2
2x*3+5y*3=355*3
Here, I am making x as same so I cross multiplied
6x+4y=790 equation 3
6x+15y=1065 equation 4
Put minus sign in any one of the equation 3 or equation 4 in order to cancel out x.
6x+4y=790
-6x-15y= -1065
0 - 11y= - 275
y= - 275/ - 11
y= 25
As we got y, we can put the value of y in equation 1 or equation 2.
3x+2y=395
3x+2*(25)=395
3x+50=395
3x=395-50
3x=345
x=345/3
x=115
As we assumed the book to x and pen to be y
price of book = Rs. 115
price of pen= Rs. 25
