The awnser is 15 inches because 1 leg is 5 inches so you times it by 3 because there is three legs and you get 15
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
The answer is b. If your problem is y=1/2x-3
Answer:
the answer is 611.2
how,-3.3x
611.2
=6
there before 614.2 there come always+if there is nothing
then,there is- before-3.3x then rule=
<h3>- + +=-</h3>
so we have to substract it
= 4 1/2 (2 3/4 + 1 3/4)
Hope you give the brainliest answer.
