Write the algebraic expression for each word problem. See if you can spot the trick problem that doesn’t need algebra!

Answers:

Question #6

(b - 7) + 10

Question #7

20 + (w × 50)

Question #8

Question #9

5 + (2 · t)

Question #10

(d · 4) + (p · 2)

6. b-7+10=Number of people on the bus

There are already b amount of people on the bus and 7 get off and 10 get on

7. 50cm x w + 20cm = total wood

because there are W amount of 50cm wood + 20cm extra

8. C/5=Amount

C pieces of chocolate split into 5 friends

9. 2xT + 5 = amount

2 packs and each pack has t amount of pens. 2 x t is the amount in the pack + 5 that you already have

10. Dx4 + Px2 = Answer

Deer have 4 legs and Pheasants have 2 legs so amount of deer x 4 plus the amount of pheasants x 2 = total amount of legs

I don't know which is the trick problem. Sorry

Hope this helps

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
