Question

0,25+×=1,2 9•×=83,25. ×÷8,5=90,1​

Answer 1

0,25 + х = 1,2               9 · х = 83,25               х : 8,5 = 90,1

х = 1,2 - 0,25                х = 83,25 : 9               х = 90,1 · 8,5

х = 0,95                        х = 9,25                      х = 765,85

Answer 2

Let's solve these equations step by step:

1. 0.25 + x = 1.29 To isolate x, subtract 0.25 from both sides: x = 1.29 - 0.25 x = 1.04

2. 9 * x = 83.25 To isolate x, divide both sides by 9: x = 83.25 / 9 x = 9.25

3. x ÷ 8.5 = 90.1 To isolate x, multiply both sides by 8.5: x = 90.1 * 8.5 x = 765.85

So, the solutions to the equations are:

1. x = 1.04
2. x = 9.25
3. x = 765.85
