Yesterday Bill bought some bottles of soda for a party he is hosting. Today he bought 8 times as many bottles of soda as he did yesterday. Bill has 27 bottles in all. Which equation would help you to find out how many bottles of soda Bill bought yesterday?

x = number of Bottles Bill brought the 1st time

8x = number of Bottles , Bill brought the 2nd times

This is an equation  

x+8x= 27

9x=27

x=3

8x= 8*3 = 24

Step-by-step explanation:

So Bill brought 3 bottles at first, then 24 the second time.

sorry if wrong

24 I think sorry if im wrong

square root

step-by-step explanation:

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
