Question

A)x•4,9=2,94 б)x+2,8=9,9.

Answer 1

а) х · 4,9 = 2,94                      б) х + 2,8 = 9,9

х = 2,94 : 4,9                           х = 9,9 - 2,8

х = 0,6                                     х = 7,1

0,6 · 4,9 = 2,94                      7,1 + 2,8 = 9,9

2,94 = 2,94                            9,9 = 9,9

Answer 2

№1

$x * 4,9 = 2,94\\x = \frac{2,94}{4,9} \\x = 0,6$

№2

$x + 2,8 = 9,9\\x =9,9 - 2,8 \\x = 7,1$

Answer 3

To solve these equations for "x," you can follow these steps:

Equation 1: x * 4.9 = 2.94

1. Divide both sides by 4.9 to isolate x:

   x = 2.94 / 4.9

2. Calculate the result:

   x ≈ 0.6

Equation 2: x + 2.8 = 9.9

1. Subtract 2.8 from both sides to isolate x:

   x = 9.9 - 2.8

2. Calculate the result:

   x = 7.1

So, the solutions to the equations are:

1. For the first equation, x ≈ 0.6
2. For the second equation, x = 7.1
