Tìm x: x × 2 = 1846. Hỏi x = ?
A. 3629
B. 923
C. 932
D. 3692
a) 2368 x 125 + 2368 x 8775
b) 1995 x 3692 + 3692 x 5
c) 117 x 89 + 117
a) 2368 x 125 + 2368 x 8775
= 2368 x ( 125 + 8775 )
= 2368 x 8900
= 21075200
b) 1995 x 3692 + 3692 x 5
= ( 1995 + 5 ) x 3692
= 2000 x 3692
= 7384000
c) 117 x 89 + 117
= 117 x ( 89 + 1 )
= 117 x 90
= 10530
a) 2368 x ( 125 + 8775) = 2368 x 8900 = 21075200
b) 3692 x (1995 + 5 ) =3692 x 2000 =7348000
c) 117 x ( 89 + 1 ) = 117 x 90 = 10530
Tìm X:
X x 2 = 1846
Tìm x:
x x 2 = 1846
X x 2 = 1846
X = 1846 : 2
X = 923
Tìm y biết:
a. y – 6 : 2 – ( 48 – 24 x 2 : 6 – 3) = 0
b. (7 x 13 + 8 x 13) : ( 9 2 3 – y) = 39
a. Tính đúng y = 40
b. Tính đúng y = 4 2 3
tìm x biết:
3692:x=26
3692 : x = 26
x = 3692 : 26
x = 142
Vây x = 142
