Solve for a. 0.25+0.5 = 4.5

You didn't add the variable but I will show uou all the ways.

0.25a+0.5 = 4.5   value of a is 16

0.25+0.5 = 4.5a    value of a is 6

Step-by-step explanation:

First way:

0.25a+0.5 = 4.5       Subtract 0.5 on both sides

       0.25a = 4           Divide 0.25 on both sides

               a = 16

Second way:

0.25+0.5 = 4.5a      Combine like terms

          0.75 = 4.5a      Divide 4.5 on both sides

                6 = a

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)
