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.

cut 138 centimeters off

step-by-step explanation:

250-112 = 138

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
