You would need 105 of sodium I found how much increase there was from 30 to 75 by doing 75/30 which is 2.5 that means the new amount of sodium would be 2.5 times 42 which is 105. You could also set up ratios and cross multiply like the picture I sent

Find an equation of variation in which y varies inversely as x and y=5 and x=21. Then find the value of y when x=10.

finlep [7]

Answer:

see explanation

Step-by-step explanation:

Given that y varies inversely as x then the equation relating them is

y = $\frac{k}{x}$ ← k is the constant of variation

To find k use the condition y = 5 , x = 21

k = yx = 5 × 21 = 105

y = $\frac{105}{x}$ ← equation of variation

When x = 10, then

y = $\frac{105}{10}$ = 10.5
