Inversely variation means xy = c, where c is a constant
Since when y = 12 x = 5, then c = 12*5 = 60
So xy = 60
Now when x = 3, y = 60/3 = 20
Answer:
Step-by-step explanation:
4.50 /2 = 2.25
11.25/5 = 2.25
22.50/10 = 2.25
Answer:
1/2
Step-by-step explanation:
Answer:
I hope this help
Step-by-step explanation:
x + y - 5
subtract 0 from the equation above
Answer:
9 ft
Step-by-step explanation:
Write and solve an equation of ratios, as follows:
8 in x
-------- = -------
7 in 8 ft
Cross-multiplying, we get: 64 in-ft = 7x in
Dividing both sides by 7 in, we get:
64 in-ft
------------ = 9 ft (rounded down from 9.143 ft)
7 in
