Four less the product of 5 and a number is at most 10

5n - 4 ≤ 10, or if you are looking for what n equals, n = 2.8

Step-by-step 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
