Each trip, a bus drops off more fans at a concert. on the first trip, the bus dropped off 30. on the 14th trip, which was the last one, the bus dropped off 95 fans. how many fans did the bus deliver to the concert in total

There are 875 fans the bus deliver to the concert in total.

Step-by-step explanation:

Since we have given that

On the first trip, the bus dropped off = 30

Here a = first term = 30

On the 14 trip, the last trip, the bus dropped off = 95

i.e.

So, the total number of fans the bus deliver to the concert is given by

Hence, there are 875 fans the bus deliver to the concert in total.

exactly you go it

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)
