Step-by-step explanation:

First find the difference between the amounts.

7,400, 000 - 6, 900,000 = 500, 000

You may solve this ratio by cross multiplying. To do this, you multiply the numbers diagonally across from each other.

x/10 = 1/5
10(1) = x(5)
10 = 5x
2 = x

Answer:
x = 2

Y is directly proportional to x when y=30, x=6

lbvjy [14]

Answer:

see explanation

Step-by-step explanation:

Given that y is directly proportional to x then the equation relating them is

y = kx ← k is the constant of proportionality

To find k use the condition when y = 30, x = 6

k = $\frac{y}{x}$ = $\frac{30}{6}$ = 5

y = 5x ← equation of proportionality

When x = 12, then

y = 5 × 12 = 60
