Answer:
y = c/x where c is a constant
Step-by-step explanation:
For y to vary inversely with x we know it must be something like y = 1/x which is the direct inverse. However this could be multiplied by a constant and still vary inversely with x, so let us define c as a constant, then y = c / x varies inversely with x
Hey there!
2/3 = a/30
First: you have to CROSS MULTIPLY the given numbers
2(30) = 3(a)
2(30) = 60
3(a) = 3a
New EQUATION: 3a = 60
Second: DIVIDE 3 to BOTH SIDES
3a/3 = 60/3
CANCEL out: 3/3 because that gives you 1
KEEP: 60/3 because that helps you solve for your a-value
60/3 = a
60/3 = 20
Therefore, your answer is: a = 20
Good luck on your assignment and enjoy your day!
