On evaluating the decimal expression given by →

6.59 + (− 7.8) − ( − 2.41), we get 1.2

What are decimal numbers?

A decimal is a number that consists of a whole and a fractional part. For example -  9.3, 5.4, 9.8 etc.

Given is the following expression -

6.59 + (− 7.8) − ( − 2.41)

The given decimal expression is -

6.59 + (− 7.8) − ( − 2.41)

Simplifying it -

6.59 - 7.8 + 2.41

6.59 - 5.39

1.2

Therefore, on evaluating the decimal expression given by →

6.59 + (− 7.8) − ( − 2.41), we get 1.2.

Answer:

1,2

Step-by-step explanation:

6,59-7,8+2,41=1,2

Answer: (a) 0.87x

              (b) 0.87x = 174

              (c) 200 players

Step-by-step explanation:

Let x be the total number of players who signed up for the season,

since 13% dropped , it implies that 13% of x dropped out , which means 0.13x dropped out.

To know the players who finished the league , it implies

x - 0.13x = 0.87x

This means that 0.87x finished the league

(a) The expression for the number of players who finished the season will therefore be 0.87x , this is as a result of subtracting those that dropped out (0.13x) from those that signed up ( x)

(b)  The equation to represent the number of players who signed up for the soccer will thus be:

x - 0.13x = 174 , since it was given that 174 finished the league, this implies

0.87x = 174

(c) Solving the equation, we have

0.87x = 174

0,87x / 0.87 = 174 / 0.87

x = 200

Therefore 200 players signed up for the league

Step-by-step explanation:

a. 87% finished the season because 13% dropped

b. 100×174 = 87x

c. 17400 = 87x ➡ x = 17400 ÷ 87 ➡ x = 200 player signed up for the soccer league.
