Which algebraic equation best represents the verbal sentence shown? "Seven times the sum of a number and twelve is twenty."
n +84 = 20
0 7(n + 12) = 20
07n + 12 = 20
0 12(n + 7) = 20

7(n+12)=20

Step-by-step explanation:

With these problems I like to work backwards a bit and break each piece down.

Start out with the answer being 20

So, equation=20

Now, look at the "the sum of a number and 12". In terms of an equation, this would be n+12.

The last piece is that n+12 is multiplied by 7.

Thus, 7(n+12)=20

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.
