Can you Help me please!!

Step-by-step explanation:

100 Let x = adult ticket

y = student ticket

6x + 12y = 186      (i)

11x + 6y = 197      (ii)

                      (i)              6x + 12y = 186

                      (ii)*2        22x + 12y = 394

                                   (-)      (-)       (-)

subtract (ii) from(i)        -16x             = -208

                                                     x = -208/-16

                                                     x = 13

x = 13 in equation (i)

6*13 +12y = 186

  78 + 12y= 186

            12y = 186 - 78

             12y = 108

                 y= 108/12

                  y = 9

Price of an adult ticket = $13

Price of a student ticket = $9

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
