Kayden had math and reading homework tonight. kayden can solve each math problem in 5 minutes and he can read each page in 1.5 minutes. write a system of equations that could be used to determine the number of math problems kayden solved and the number of pages he read. define the variables you use to write the system.

1.5a+5b=t

a=reading time for each page

b=solving math a problem

t=total time

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

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
