One of the steps kim used to solve an equation is shown below.
4x−6=22
4x-6+6=22+6
which statement describes the procedure she used in this step and identifies the property that justifies the procedure?
pls : (
a: kim subtracted 6 from both sides of the equation. this procedure is justified by the additive property of equality. b: kim added 6 to both sides of the equation. this procedure is justified by the additive inverse. c: kim added 6 to both sides of the equation. this procedure is justified by the additive property of equality. d: kim subtracted 6 from both sides of the equation. this procedure is justified by the additive inverse. description

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.

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
