Answer 1

3.5m+m=9.9

4,5m=9.9

m=9.9/4,5

m=2,2

Answer 2

4,5m=9,9

m=9,9:4,5

m= 2,2

 

проверка:

4,5*2,2= 9,9

Answer 3

To solve the equation 3.5m + m = 9.9, we can combine the like terms on the left side of the equation:

3.5m + m = 4.5m

Now, the equation becomes:

4.5m = 9.9

To isolate the variable m, we divide both sides of the equation by 4.5:

(4.5m) / 4.5 = 9.9 / 4.5

m = 2.2

Therefore, the value of m that satisfies the equation 3.5m + m = 9.9 is m = 2.2.
