Sophia babysits for $15 per hour. She mows lawns for $12 per hour. This weekend, Sophia babysits 4 more hours than she mows lawns.
She earns a total of $195. Write a system of equations that can be used
to find how many hours she worked at each job.
Let b be hours babysitting. Let m be hours mowing.
b=m+ 4
hours worked
15b + 12m = 195 total money earned (please help me with both parts)

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.

the answer i believe is 27 units.

step-by-step explanation:

2 over 5 and 4 over 15

don’t know last one sorry
