Sean is employed as a truck driver. He drives x hours a week and is paid $21.60 per hour. Also he is paid $250 for food per week
allsm [11]

Answer:

Hours driven= 40 hours

Step-by-step explanation:

Giving the following information:

Variable income= $21.6 per hour

Fixed income= $250

Total income= $1,114

<u>To calculate the number of hours driven, we need to use the following formula:</u>

Total income= fixed income + hourly rate*number of hours

1,114 = 250 + 21.6*x

864 = 21.6x

864 / 21.6 = x

40=x

Hours driven= 40 hours

Solve for x - PLEASE NEED HELP, this is my 3rd time posting it.
mafiozo [28]

Answer:

x=58

Step-by-step explanation:

First, remember that the maximum degree of an angle totals 360°.

Since we already have 294°, this means that what is left must total 360\textdegree - 294\textdegree= 66\textdegree.

Therefore, this means that our two smaller angles must equal 66°. So:

(36)+(x-28)=66

Solve for x. Add on the left:

x+8=66

Subtract 8 from both sides. Therefore, the value of x is:

x=58
