2= 7+ b/4 in two-step equation-integers

b=-20

Step-by-step explanation:

We will have to solve this question based on how the question is given

So let's solve the given question

2=7+b/4

To start by finding the LCM for the right side and the LCM is 4

2=28+b/4

Let's cross multiply

2×4=28+b

8=28+b

Let's make b the subject of formula by substrating 28 from both sides

-20=b

Therefore the final answer is b=-20

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.

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.
