Harry wants to buy some ice cream for his friends and himself. At the ice cream parlor, one ice cream costs $3.99. Which expression below could you use to compute the cost of 4 ice creams? A. 4($4.00) – 4($0.01) B. 4($4.00) – 4($0.99) C. 4($4.00) + 4($0.01) D. 4($4.00) + 4($0.99)

10 b/c 5*2 =10

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)

54 it just is
