Answer: 5n - 4 ≤ 10, or if you are looking for what n equals, n = 2.8
Explanation:
Four less the product of 5 and a number (n) is at most ten
You would first take the product of 5 and a number (n), which is 5n, then subtract 4, 5n - 4, then it is at most ten, which would be less than or equal to ten.
Now find n:
5n - 4 ≤ 10
5n - 4 + 4 ≤ 10 + 4
5n ≤ 14
5n/5 ≤ 14/5
n ≤ 2.8
Check:
5*2.8 - 4 ≤ 10
14 - 4 ≤ 10
10 ≤ 10
