Maggie has a job working in an office for $ 10 $10 an hour and another job driving a tractor for $ 12 $12 an hour. one week she works in the office twice as long as she drives the tractor. her total income for that week is $ 416 $416. how many hours did she spend at each job?

Step-by-step explanation:

let she works in driving tractor=x

working in office=2 x hrs

2x(10)+12x=416

32x=416

x=416/32=13 hrs

she works in driving tractor=13 hrs.

she works in office=26 hrs.

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
