Lin’s family has completed 40% of a trip. They have traveled 24 miles. How far is the trip? (If you get stuck, draw a tape diagram) Then

Marco bought a doll for his little sister. The price on the tag was $35, but it was on sale for 80% off. How much did Marco pay for the doll?

1) 60 miles

2) 7 dollars

Step-by-step explanation:

1) Question 1

Let x be equal to the full distance of the trip

Divide both sides by 0.4

Therefore, the trip is 60 miles long.

2) Question 2

Let y be equal to the price that Marco paid for the doll.

We multiply 35 by 1-0.8 because the doll is 80% off, meaning he's paying for 20% of the original price

Therefore, Marco paid $7 for the doll.

I hope this helps!

step-by-step explanation:

use a calculator!

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
