So it's a scale. On your graph, there should be units, or little squares made up of lines. For example, if you have a square that's one unit/line on each side, in real life it's going to be 2cm on each side. If you draw a square that's 4 lines/units on each side, it means that it's 8cm on each side, because that's 2cm for each little line.

I’m confused on this one
sammy [17]

The angles that form similarity are those that are vertically opposite and 2 pairs that are equal because the for a Z formation.


Since <LPM = <ONM then


\dfrac{LP}{NO}=\dfrac{LM}{MO}\\ \\\dfrac{5x - 10}{4x-9}=\dfrac{16}{12} Cross multiply

12*(5x - 10) = 16*(4x - 9) Remove the brackets on both sides.

60x - 120 = 64x - 144 Subtract 60x from both sides.

- 120 = 64x - 60x - 144

-120 = 4x - 144 Add 144 to both sides.

-120 + 144 = 4x

24 = 4x Divide by 4

24/4 = x

x = 6

At the movie theatre, child admission is
Dmitriy789 [7]
Child = $5.70
Adult = $9.80

- We can conclude that the amount of adult is double the amount of child tickets bought. (total of $556.60)

For this, you will need to divide the total amount by two and draw a tree chart with each of the numbers to get the seperation of the two. I would find out how many 9.80s or 5.70s go into $56.60 so you'll just have $500
