Write an equation to match each situation a. → Mary had a debt of $30. She earned $15 more now she has .
b.→ A diver was at the depth of 10ft . Then he sank 5ft. then he sank 15ft more . now he is at depth of ft.
c.→ The temperature was 2*c and feel 7* . Then it rose 4*. Now the Temperature is *c.

-15$

30 ft

6*c

I hope this helps

Step-by-step explanation:

a. → Mary had a debt of $30. She earned $15 more now she has _x = $30 + $15.

b.→ A diver was at the depth of 10ft . Then he sank 5ft. then he sank 15ft more . now he is at depth of _x = 10 + 5 + 15 ft.

c.→ The temperature was 2*c and feel 7* . Then it rose 4*. Now the Temperature is _x = 2 + 4 *c.

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.

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
