Answer:
9 Feet
Step-by-step explanation:
Lets start with a ratio:
1:3
Now lets look at the other ratio:
3:?
If the 1 turned into a three in the second ratio, then what will the 3 in the first ratio turn into?
9!
Because 1x=3 should be equivalent to 3x=9
Lets check our work:
x=3
3x=9
Simplify by dividing by 3 on both sides:
It worked!
The answer is 9 feet. If the air hockey table is 3 inches long and 1 inch = 3 feet, 3 x 3 = 9.
I entered it in and it was .9993319736
-19
-1/6
(10 - 8)/(-21 + 9)= 12/-12= -1
y - 8 = -1(x + 9)
y - 8 = -x - 9
y = -x - 1
