write the direct variation equations, then find y when x =5. show all work and explain.

y=20 when x=5.

Step-by-step explanation:

The easy way to solve this problem is to find what x was multiplied by, and then multiply the y by the same number.

To find the amount x was changed by, we can divide the result by the initial value.

Like this:  5/3=1.666667

Now we just need to multiply the initial y by 1.66667 to get the result.

12*1.6666667=20.

y=20 when x=5.

Hope this helps!

y=20

Step-by-step explanation:

Direct variation is given by

y = kx

When y =12 x =3

12 = k3

Divide each side by 3

12/3 = 3k/3

4=k

The equation is

y = 4x

Now find y when x = 4

y = 4(5)

y =20

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
