80
80 + 50 = 130
thirty plus 50 equals 80 it is quite simple. all you do is you just add 3 and 5 then add on the zero.
80 + 10 = 90 - 0 or 80 + 10 = 90 is true

ninety 4 + 6 = 10 30 + 50 = 80 10 + 80 = 90 or 56 + 4 = 60 60 + 30 = 90 same as 34 + 6 = 40 40 + 50 = 90
The result of the equation - 130 plus 80 plus 50 plus 80, is found as follows;130 + 80 + 50 + 80= ( 130 + 80 ) + 50 + 80= 210 + ( 50 + 80 )= 210 + 130= 340Answer = 340
Not with those numbers
80 + 10 equals 90 so the missing value is zero, ie 80 + 10 = 90 - 0
Subtract 2x from each side: 30 = 10x - 50;Add 50 to each side: 80 = 10xDivide each side by 10: 8 = x
thinking is amazing
The result of the equation - 50 plus 90 plus 60 plus 80, is found as follows; 50 + 90 + 60 + 80 = ( 50 + 90 ) + 60 + 80 = 140 + ( 60 + 80 ) = 140 + 140 = 280 Answer = 280
