Bonita thought of a number and divided it by 8.

what can she do to get back her original number?

a. divide by 8 again

b. subtract 8

c. multiply by 8

d. add 8

Multiply by 8

Step-by-step explanation:

To undo an arithmetic operation, such as division, an inverse operation needs to be applied, in this case multiplication.

Let x denote the number Bonita thought of. She then divided it by 8, so the result was x/8. She then, for some reason, forgot the original number x but still had access to x/8 and still remembered that she divided by 8. She can get the orginal number, x, by multiplying: (x/8)*8=x.

Multiplication and Division are mutually inverse. Addition and Subtraction are another example of mutually inverse operations.

C. multiply by 8 because multiply is backwards division

Step-by-step explanation:

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
