Mathematics
1 answer:
babunello [35]3 years ago
4 0

Answer:

4\ frac {1}{9}

Step-by-step explanation:

The recurring part is .111111

Now the number is 4.1111111111111 and let this number be x.

If you get 10x we shall have

10x=41.1111111111..... Equation 1

x=4.11111.... Equation 2

Subtract equation 2 from 1

10x-x=41.11111111-4.11111111=37

9x=37 hence x=37/9

The number will be \frac {37}{9}=4\frac {1}{9}

Write an appropriate direct variation equation if y = 18 when x = 2
Sergeu [11.5K]

Answer:

y=9x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form k=\frac{y}{x} or y=kx

In this problem we have

y=18 when x=2

Find the value of the constant of proportionality k

k=\frac{y}{x} ----> k=\frac{18}{2}=9

therefore

The equation is equal to

y=9x
