Answer:

-1/4 ≤ x

Explanation:

Let's try to represent this with numbers in order.

10 is no more than means it's an inequality. No more than means less than or equal to.

It says 4 times the sum of something, so it sounds like we have to put something in parentheses.

The sum of twice a number and 3 can be written as:

2x + 3

4 times that can be written as:

4(2x +3)

So at the end its:

10 ≤ 4(2x + 3)

Using the distributive property, it becomes:

10 ≤ 8x + 12

Isolating x by subtracting 12 on both sides makes it:

-2 ≤ 8x

Dividing by 8 gives:

-1/4 ≤ x
