Question

Вместо звездочки поставьте число ,чтобы получилось верное равенство : 1)7*(*)=-21; 2)-15*(*)=60; 3)-5*(*)=-30; 4)(*)*(-4)=36; 5)(*)*(*0=-63; 6)(-25)*(*)=-100; (*)-неизвестное число ,*-умножить

Answer 1

1) -3
2) -4
3) 6
4) -9
5) 6.3*(-10) = -63
6) 4

Answer 2

Решение:

1) 7 * (*) = -21

To find the value of (*), we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 7:

(7 * (*)) / 7 = -21 / 7

(* = -3)

So the correct value for (*) in order to make the equation true is -3.

2) -15 * (*) = 60

Similarly, to find the value of (*), we divide both sides of the equation by -15:

(-15 * (*)) / -15 = 60 / -15

(* = -4)

Therefore, the value of (*) that satisfies the equation is -4.

3) -5 * (*) = -30

Dividing both sides of the equation by -5:

(-5 * (*)) / -5 = -30 / -5

(* = 6)

The value of (*) that makes the equation true is 6.

4) (*) * (-4) = 36

To find the value of (*), we divide both sides of the equation by -4:

((* * (-4)) / -4 = 36 / -4

(* = -9)

So the correct value for (*) in order to satisfy the equation is -9.

5) (*) * (*0) = -63

Here, it seems there might be a typo as (*0) is not a valid expression. Please provide the correct expression so that I can assist you further.

6) (-25) * (*) = -100

Dividing both sides of the equation by -25:

((-25) * (*)) / -25 = -100 / -25

(* = 4)

Therefore, the value of (*) that satisfies the equation is 4.

In summary:

1) (*) = -3 2) (*) = -4 3) (*) = 6 4) (*) = -9 5) Invalid expression (please provide the correct expression) 6) (*) = 4
