Help please! Will give Question 3. You and a friend are doing math homework together. You have to solve the equation 5x+4x-68=34-8x. Your friend arrives at the answer x= -2. Is she correct explain.

she is correct because if you do all of the math correctly than you will get x=-2

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.

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.
