Question

477. Що потрібно поставити замість зірочок, щоб одержати правильну рiвнiсть? 1) (**) 11 = 88-66m; 2) (15+*) 4 = * +4a.​

Answer 1

Ответ:

1) (8-6m) 11=88-66m

2) (15+а) 4=60+4а

Answer 2

1) (8-6m) 11=88-66m
2) (15+a) 4=60+4a

Answer 3

1) To solve the equation (**)+11=88-66m, we need to determine the value that should replace the asterisks in order to obtain a correct equality.

Let's break down the equation step by step:

(**) + 11 = 88 - 66m

To solve for (**), we need to isolate it on one side of the equation. We can do this by subtracting 11 from both sides:

(**) = 88 - 66m - 11

Simplifying further:

(**) = 77 - 66m

Therefore, the value that should replace the asterisks to obtain a correct equality is 77 - 66m.

2) Now let's move on to the second equation: (15 *) 4 = * 4a.

Similarly, we need to determine the value that should replace the asterisks in order to obtain a correct equality.

Let's break down the equation step by step:

(15 *) 4 = * 4a

To solve for (*), we need to isolate it on one side of the equation. We can do this by dividing both sides by 4:

(15 *) / 4 = (* 4a) / 4

Simplifying further:

15 * = a

Therefore, the value that should replace the asterisks to obtain a correct equality is a.

In summary: 1) ()+11=88-66m can be solved by replacing the asterisks with 77 - 66m**. 2) (15 *) 4 = * 4a can be solved by replacing the asterisks with a.
