The small triangle and big triangle are similar - this means they have the same angles. So, if you know the ratio of a side of the big triangle (12) to a side of the small triangle inside it (4), you know the ratio of the other sides. In this case, the side ratio (small to big triangle) is 1/3. Thus, the missing side length is 18/3=6.

Answer:
B) y=5x-17
Step-by-step explanation:
I got this answer, by first making sure it was parallel to y=5x+7. Which was easy because the only thing they need to be parallel is the same slope, in this case was 5. Next I pluged in (4,3) to y=5x-17. I substituted 4 into x and got 20. Then I substituted 3 into y. Since 20-17 is equal to 3, then B. is your answer.
Answer: t = 1/3
Divide both sides by 60.
<u>4 x 10 x 1.5</u><u><em>t</em></u><em> = </em> 20/60
60

Answer:
1.25/1.5
Step-by-step explanation:
height (rise) 1.25m
Width (run) .3m per stair
5 stairs x .3m per stair= 1.5m
Rise/run= 1.25/1.5
