55% of 20 is 11. the answer is 20
Answer:
x = 3 (see below)
Step-by-step explanation:
To solve for x, you need to isolate the variable to one side of the equation. To do that, you need to use reverse operations. For example, the reverse operation of subtraction is addition.
In this case, we have:
15 = 5x
5x is the same thing as 5 (x) or 5 times x. This means the reverse operation is division. So, we need to divide both sides of the equation by 5:
15 = 5x
----- ----
5 5
--------------
3 = x
x = 3
So n will be the unknown, and the expression is:
6n = 24
from where we can find the number n:
n = 24/6
n = 4
The greatest six-digit number they could make is 998,877 I know this because I used the largest digits and put them in order from largest to smallest.
Hope this helps
