The table shows the price of two cereal brands
and the number of ounces per box. Which is the
better price per ounce?

< 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)

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.

210/22 = 9.55

since he can't take part of a person to the game the answer is 9 people

hope this !

the answer is b.

volume: 366π

i got it down.
