Answer:

Step-by-step explanation:

We have been given an expression

We need to find the sum of the given expression we will first take the LCM of the denominator which is then we get

Therefore the required sum that is sum of the expression is

Answer: You get the answer x+5/x+3.

This is because all of the fractions have the same denominator, so just add the numerators and put them over x+3.

When Lawrence filled his pool, the water line was 4 in. from the edge of the pool. For the next 5 days, Lawrence noticed that the distance between the water line and the edge of the pool increased by 0.5 in./day. What is the slope of the line that models this situation? A. 0.1 B. 0.5 C. 3.5 D. 4

The slope of the line that best models the situation is the rate of change in the level of the pool. From the given problem, the rate of change is 0.5 / day. Thus, the slope is 0.5. The answer to this item is letter B.

Step-by-step explanation:

Consider the provided information.

We need to find examples of decimals in a newspaper or magazine write a real world problem in where you have to divide decimals.

Suppose there is an advertisement in news paper that you can buy 3.5 kgs of coffee in $24.5. So find the cost of 1 kg coffee.

To find this simply divide the decimals as shown:

Hence, the cost of 1 kg coffee is $7.
