Solve the equation<br> 1/x + 1/3x = 4

Llana [10]

Answer:

x = $\frac{1}{3}$

Step-by-step explanation:

$\frac{1}{x} + \frac{1}{3x} = 4$ (Multiply everything by LCM)

$3x*\frac{1}{x} + 3x*\frac{1}{3x}=3x*4$ (Simplify the fractions)

$3+1=12x\\4=12x\\x=4/12\\x=\frac{1}{3}$

Please answer this correctly

Margaret [11]

Answer:

$22.1

Step-by-step explanation:

To solve this, you must multiply the amount of the items by its cost.

This is the amount of yams in decimal form: $4\frac{1}{2}$ = 4.5

This is the amount of carrots in decimal form: $4\frac{3}{10}$ = 4.3

4.5 * 3 = 13.5

4.3 * 2 = 8.6

Now we add them together to get the total cost.

13.5 + 8.6 = 22.1

(a.) constant of proportionality k
y = kx
y/x = k
use the point (1,30)
30 = k

The slope will be the same answer, theyre the same thing
use two points (1,30) and (2,60)
m = (60-30)/(2-1) = 30

(b.) The equation for the line is: y = 30x
