Simplify this expression: -2.15m + 6 + 10.3m

8.15m + 6

Step-by-step explanation:

To simplify, combine like terms. The only like terms here are the -2.15m and 10.3m because they both have a variable next to them.

Add the numbers together and leave the variable the same.

-2.15m+10.3m = 8.15m

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
