Afla nr necunoscute :
b) 824-240:x=800
245+50×x=745
c) x :9×8=808
x ×6:9=32
dau coronita

Answer 1

824 - 240 : x = 800
240 : x = 824 - 800
240 : x = 24
x = 240 : 24
x = 10

245 + 50 x X = 745
50 x X = 745 - 245
50 x X = 500
x = 500 : 50
x = 10

x : 9 x 8 = 808
x : 9 = 808 : 8
x : 9 = 101
x = 101 x 9
x = 909

X x 6 : 9 = 32
X x 6 = 32 x 9
X x 6 = 288
X = 288 : 6
x = 48

Answer 2

b) 824-240:x=800
-240:x=-24
x=10


245+50x=745
50x=500
x=10
c) x:9*8=808
x:9=101
x=909



6x:9=32
6x=288
x=48
