There is no r in 128 plus 253
253 + 638 = 891
345 + 253 = 598
The answer to that is 256.
140 + 145 + 132 + 128 = 545
253
That would be 253.
32 + 128 = 160
272 + 128 = 400
No, it is not. Substitute and check. You have 128 + 16r. So now, if r=9, then the equation would be 128 = 16x9. But, 16x9 is 145 and is not equal to 128. Thus, r=9 is not the solution. The solution is r+ 128/16 which is equal to 8. Thus, the actual solution is r = 8.
320 ÷ 128 = 2 r 64 128 ÷ 64 = 2 r 0 hcf of 320 and 128 is 64.
its a math equation
179+74=253
