What is the value of 6x8-4[7+(8-3)] ?

Answer:

240; 24

Step-by-step explanation:

Given that:

Sum of two numbers = 264

One number ends with '0'

Second number = first number without '0'

Let the first number be 'a'

Since the second number is the first number with '0' erased, then,

Second number = (a ÷ 10)

Therefore, the expression becomes :

a + a/10 = 264

Multiply the equation by 10

10a + a = 2640

11a = 2640

a = 2640/11

a = 240

Therefore ;

a = 240 ;

a/10 = 240/10 = 24

The numbers are 240 and 24

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.

Answer:

-8/17

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-75-(-51))/(31-(-20))

m=(-75+51)/(31+20)

m=-24/51

m=-8/17
