Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify the expressions to be combined: +0.5x +0.5x and +714x +7\frac{1}{4}x .
  • Step 2: Convert the mixed number 714 7\frac{1}{4} to a decimal or improper fraction.
  • Step 3: Perform the addition of coefficients.

Now, let's work through each step:
Step 1: We are given the expressions +0.5x +0.5x and +714x +7\frac{1}{4}x . These need to be combined.

Step 2: Convert the mixed number 714 7\frac{1}{4} to a decimal or improper fraction.
As an improper fraction, 714=294 7\frac{1}{4} = \frac{29}{4} .
As a decimal, 714 7\frac{1}{4} can be approximated to 7.25 7.25 .

Step 3: Add the coefficients:
Using decimals: 0.5+7.25=7.75 0.5 + 7.25 = 7.75 .
Using fractions: Convert 0.5 0.5 to 12 \frac{1}{2} and add 12+294 \frac{1}{2} + \frac{29}{4} .

First, convert 12 \frac{1}{2} to have a common denominator with 294 \frac{29}{4} , which is 24 \frac{2}{4} .
Sum these, 24+294=314 \frac{2}{4} + \frac{29}{4} = \frac{31}{4} which simplifies to 734 7\frac{3}{4} .

Thus, (+0.5x)+(+714x)=734x (+0.5x)+(+7\frac{1}{4}x) = 7\frac{3}{4}x .

Therefore, the solution to the problem is 734x 7\frac{3}{4}x .

Answer

734x 7\frac{3}{4}x
