Answer:
30/52
Step-by-step explanation:
y = 25x / 5 is each function is an example of exponential growth or decay.
What does exponential growth look like in math?
- A typical illustration of exponential expansion is population increase. Take a population of bacteria as an example. It seems sense that the rate of population increase would be inversely correlated with the population's size.
- After all, the number of bacteria grows more quickly the more there are for them to reproduce.
y= 25/7(7/5) x
y = 25/5 x
y = 25x / 5

Answer:
x = 5
Step-by-step explanation:
The sides are in proportion.
The proportion is 20/36
The other sides must be in the same proportion: 5x / 45
5x/45 = 20/36 You can reduce the left side by dividing top and bottom by 5
1x / 9 = 20/36 You can reduce the right side by dividing by 4
x / 9 = 5/9 at this point you should be able to see that x = 5, because the denominators are the same.
That is the answer.
However you can extend this by cross multiplying
9x = 45 Divide by 9
x = 45/9
x = 5
