Question

Помогите решить (m-15)÷25=13
a÷12-26=85. 112-r×2=60

Answer 1

Ответ:

1.

$(m - 15) \div 25 = 13$

$\frac{m - 15}{25} = 13$

$m - 15 = 325$

$m = 325 + 15$

$m = 340$

2.

$a \div 12 - 26 = 85$

$\frac{1}{12} a - 26 = 85$

$a - 312 = 1020$

$a = 1020 + 312$

$a = 1332$

3.

$112 - r \times 2 = 60$

$112 - 2r = 60$

$- 2r = 60 - 112$

$- 2r = - 52$

$r = 26$
