Painter a charges 372 plus 12 per hour and painter b charges 280 plus 15 per hour in how many hours will they cost the same

Painter A  372+12h

Painter B 280+15h

372+12h=280+15h

subtract 12h from each side

372 = 280 + 3h

subtract 280 from each side

92 = 3h

divide each side by 3

30 2/3 =h

the cost the same at 30 2/3 hours

529 and 531

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
