Ted has 60 books on 6 shelves. The bottom shelf has 15 books. The other shelves have an equal number of books. Write an equation that can be used to
find b, the number of books on each of the top 5 shelves. Then, solve the
equation.

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14

x< -17/2 hope this

we know that

1) the inscribed angle measures half of the arc it comprises.

so

m∠dgf= > expression

2) the opposite angles in an inscribed quadrilateral are supplementary angles

so

m∠dgf=

m∠dgf=°

substitute in the expression to find the value of arc ef

therefore

the answer is

the measure of the arc ef is

the answer is b
