Question

1) 4,9х = 2,94 ; 2) 0,0091 : х = 0,7 ; 3) х : 2,3 = 5,6

Answer 1

Пошаговое объяснение:

1) 4,9х=2.94

х=2,94:4.9

х=0.6

2) 0.0091/х=0.7

91/10000х=0.7

91=0.7*10000х

91=7000х

91:7000=х

0,013=х

3) х:2.3=5.6

х=5.6*2.3

х=12,88

Answer 2

To solve these equations, you can isolate the variable x in each equation. Here's how you can do it for each of them:

1. 4.9x = 2.94

   To isolate x, divide both sides by 4.9: x = 2.94 / 4.9 x = 0.6

2. 0.0091 / x = 0.7

   To isolate x, multiply both sides by x to get x out of the denominator: 0.0091 = 0.7x

   Now, divide both sides by 0.7 to solve for x: x = 0.0091 / 0.7 x ≈ 0.013

3. x / 2.3 = 5.6

   To isolate x, multiply both sides by 2.3 to get x on one side of the equation: x = 5.6 * 2.3 x ≈ 12.88

So, the solutions are:

1. x = 0.6
2. x ≈ 0.013
3. x ≈ 12.88
