One number is 4 times another number. The sum of their reciprocals is 5. What are the two numbers?

The two number are:

Step-by-step explanation:

Given that one number is 4 times another number, the first equation is

Next, the sum of their reciprocals is 5, so

Now, we have the system of equations

Let us solve the system of equations

substitute y = 4x in the equation

Least Common Multiple of x, 4x:  4x

Adjust fractions based on L.C.M

Multiply both sides by 4x

Simplify

switch sides

Divide both sides by 20

Simplify

For y = 4x, substitute

Therefore, the two number are:

Verification:

substituting

L.H.S = R.H.S

and

substituting

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
