( x + 5 ) + ( x + 10 ) + ( x + 15 ) +...................+ ( x + 100 ) = 1110:
(100-5): 5 + 1=20
= x+ ( 5+ 10)x20:2)= 1110
=x+ 150=1110
x= 1110 - 150
x= 960
( x + 5 ) + ( x + 10 ) + ( x + 15 ) +...................+ ( x + 100 ) = 1110:
(100-5): 5 + 1=20
= x+ ( 5+ 10)x20:2)= 1110
=x+ 150=1110
x= 1110 - 150
x= 960
(x+5 ) + (x+10 ) + (x+15) + ... +(x+100) = 1110
(x+5)+(x+10)+(x+15)+…+(x+100)=1110
(x+5)+(x+10)+(x+15)+...(x+100)=1110
( x+5 ) + ( x+10) + ( x+15) + ........ + ( x+ 100) = 1110. Tìm x
tìm x biết : (x+5) + (x+10) + (x+15) +...+ (+100)= 1110
( x + 5 ) + ( x + 10 ) + ( x + 15 ) + ... + ( x + 100 ) = 1110
Trả lời : Tìm x = ?
(x+5)+(x+10)+(x+15)+..........+(x+100)=1100
tính nhanh:
10 x 5 + 5 + 10 + 10 + 5
tìm x :
100 + x = 15 + 15
tính nhanh tính đúng tchs mình tchs lại
tim X
a,( 25 * 12 - X - 25 ) : 25 = 4
b,180 - ( X + 15 ) : X * 20 = 100
c,125 + ( X - 25 ) * 5 + X = 150
d,X : 8 * 32 + X: 3 * 18 - X: 5 *10 = 120
