Chelsea makes $10.55 an hour working at dr. daleson’s car clinic. she plans to buy a camera, which costs $393.40. write and solve an inequality describing how many hours h chelsea will have to work to be able to buy the camera.

I'm pretty sure the answer is: 10.55h ≥ 393.40; at least 38 hours .

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.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
