Question

( x+5 ) + ( x+10) + ( x+15) + ........ + ( x+ 100) = 1110. Tìm x

Answer 1

( x + 5 ) + ( x + 10 ) + ...+ ( x + 100 ) = 1110

=>  ( x+x+x+...+x) + ( 5+10+15+...+100) = 1110

=> x . 20 + 1050

=> x . 20 = 60 

=> x = 3 

vậy x  =  3

Answer 2

( x + 5 ) + ( x + 10 ) + ( x + 15 ) + ........ + ( x + 100 ) = 1110. Tìm x

=> ( x + x + x + ... + x ) + ( 5 + 10 + 15 + ... + 100 ) = 1110

=> X x 20 + 1050

=> X x 20 = 60

=> X = 3

Vậy x bằng : 3

Answer 3

(x+5)+(X+10)+(x+15)+....+(x+100)=1110

20x+(5+10+15+...+100)=1110

20x+1050=1110

20x=1110-1050

20x=60

x=60:20

x=3

Answer 4

( x+5 ) + ( x+10) + ( x+15) + ........ + ( x+ 100) = 1110.

=(x+x+x+.....+x)+(5+10+15+...+100)=1110

=>20x+1050=1110

=>20x=60

x=3

Answer 5

( x + 5 ) + ( x + 10 ) + ( x + 15 ) + ........ + ( x + 100 ) = 1110. Tìm x

=> ( x + x + x + ... + x ) + ( 5 + 10 + 15 + ... + 100 ) = 1110

=> X x 20 + 1050

=> X x 20 = 60

=> X = 3

Answer 6

( x + 5 ) + ( x + 10 ) + ( x + 15 ) + ........ + ( x + 100 ) = 1110. Tìm x

=> ( x + x + x + ... + x ) + ( 5 + 10 + 15 + ... + 100 ) = 1110

=> X x 20 + 1050

=> X x 20 = 60

=> X = 3

Vậy x bằng : 3

Answer 7

( x + 5 ) + ( x + 10 ) + ( x + 15 ) + ........ + ( x + 100 ) = 1110. Tìm x

( x + x + x + ... + x ) + ( 5 + 10 + 15 + ... + 100 ) = 1110

x * 20 + 1050 = 1110

x * 20 = 1110 - 1050

x * 20 = 60

x = 60 : 20

x = 3

Answer 8

( x + 5 ) + ( x + 10 ) + ( x + 15 ) + ........ + ( x + 100 ) = 1110. Tìm x

=> ( x + x + x + ... + x ) + ( 5 + 10 + 15 + ... + 100 ) = 1110

=> X x 20 + 1050

=> X x 20 = 60

=> X = 3

Answer 9

Ta có :
