sam went to western playland he paid $20 to get in and $5 per ride. He has a total of $50 to spend wich equation can we use to see how many rides same can ride

the equation 20+5r=50 should help you see how many rides he can ride.

Step-by-step explanation:

20+5r=50

1. Subtract 20 from both sides.

5r=30

2. Divide by 5 to isolate r.

r=6

Sam can ride 6 rides.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
