If Y varies directly with X,
find y when X =24 if y =5
when X = 30.

We get Y=4 when X =24

Step-by-step explanation:

If Y varies directly with X,  find Y when X=24, if Y = 5  when X= 30.

We are given If Y varies directly with X, we can write:

Where k is constant of proportionality

We need to find Y when X=24, first we need to find k, the constant of proportionality.

Now, we are given: If Y = 5  when X= 30.

We can find value of k

So, k=1/6

Now, we will find Y when X = 24

and k=1/6

So, Y=4 when X =24.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
