$500
x*.8=400
divide .8 from both sides
x=500
Answer:
As an equation, the product of a number and 12 is no more than 15 would be:
12n ≤ 15
N would represent the number.
≤ means less than or equal to, which is the same as "no more than".
Divide by 2 and take the base-5 log.
We are trying to find the number that when added to 19, gives us less than 42. We can set up this simple inequality:
19 + x < 42
Now, subtract 19 from both sides:
x < 23
Our number can be anything less than 23.
