Step-by-Step Solution

Let's solve the expression 48:10x(x+5) 48:\frac{10}{x}-(x+5) .

Step 1: Change the division to multiplication by the reciprocal.

We have 48:10x=48×x10 48:\frac{10}{x} = 48 \times \frac{x}{10} .

Simplifying this, we obtain:

48×x10=48x10=4.8x 48 \times \frac{x}{10} = \frac{48x}{10} = 4.8x .

Step 2: Incorporate the subtraction operation.

We now have 4.8x(x+5) 4.8x - (x + 5) .

Distribute the negative sign:

This gives us 4.8xx5 4.8x - x - 5 .

Step 3: Combine like terms.

Simplifying further, we have:

4.8xx=3.8x 4.8x - x = 3.8x .

Thus, we end with:

3.8x5 3.8x - 5 .

Therefore, the solution to the problem is 3.8x5 3.8x - 5 .

Upon reviewing the given choices, choice 1 corresponds to our calculated result: 3.8x5 3.8x - 5 .

Answer

3.8x5 3.8x-5
