One angle = 90°
the other 3 angles = 360 - 90 = 270
so
x + 2x + a = 270 but a = 168
3x + 168 = 270
3x = 102
x = 102/3
x = 34
answer
x = 34
12/15 simplifies to 4/5, whereas all the others simplify to 2/3. Therefore, 12/15 is not equivalent to the rest.
Answer:
1. 244
2. 122

2. Divide 122 by 2.
Answer:
f(x) = 5x - 30
Yes it is a function
Step-by-step explanation:
Because when you input 0 you get -30 we know it starts at 0 or (0,-30). This gives us b in the equation y = mx + b.
We know that for every 4 cars washed it increases by 20. So 20/4 is 5. This tells us m = 5.
Plug it all in and you get y = 5x - 30 or f(x) = 5x - 30
You would measure a book with centimeters because centimeters is much more smaller than a meter and easier to measure.
