Victor read a total of 12 books over 4 months. after belonging to the book club for 5 months ,how many books will victor have read in all? solve using unit rates.

15 books

Step-by-step explanation:

Given that Victor read a total of 12 books over 4 months which means for 1 month he reads 12/4 = 3 books

Also given that he belongs to the book club for 5 months

We know that he reads 3 books in 1 month

So in 5 months he reads

step-by-step explanation:

compare

< 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)
