38.73

Step-by-step explanation:

For adding negatives, you basically just subtract. For example, -3+5. To find the answer, you subtract 3 from 5, leaving you with 2. For decimals, you add like normal, but you carry the decimal down, and leave it in the same place.

Step-by-step

1. Put the numbers in a vertical column, aligning the decimal points

2. Add each column of digits, starting on the right and working left. If the sum of a column is more than ten, "carry" digits to the next column on the left.

3. Place the decimal point in the answer directly below the decimal points in the terms.

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
