Supplementary angles always add up to 180. So you need to subtract 30 from 180. Which would give you 150. So 150 is your answer!
Answer:
1/5
Step-by-step explanation:
divide each side by 5
5x/5=1/5
simplify
x/5=1/5
it can be
12 to 15
12 / 15
12 : 15
you can write it in any of these way.
The domain is how far left and right it goes on a graph, and the range is how far up and down it goes on a graph. Because this equation is linear (if you graphed it, it would be in a straight line), both the domain and range are infinity, because it keeps going up and to the right, the larger X gets, and smaller and to the left, the more negative X gets.
Let's start with 17 seats and just bikes. That is 34 wheeles. Now, each bike we replace with a go-kart will add 2(because we take away 2 and add 4). We need to add 14 wheels. This means we will replace 7 bikes with go-karts. 7 go-karts (28 wheels) and 10 bikes (20 wheels) is the answer.
