The skating rink charges 0.75 to rent skates and 1.25 per hour to take which equation can be used to find the number of hours (h) someone skated if he or she was charged 4.50 A) h(0.75+1.25)=4.50
B) 0.75+1.25=4.50
C) 0.75+1.25h=4.50
D) 0.75h+1.25=4.50

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

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)

his answer is incorrect. i just used it, and it said it was incorrect. the answer is 0.

answer: graphs are something you write or draw and equations are math problems
