Answer 1

Решение во вложении

Answer 2

Пошаговое объяснение:

3 а - ( 40 - 3 ) = 3

3 а - 27 = 3

3 а = 30

а = 10

( 98 - 56 ) : b = 24: 4

42 : b = 6

42 = 6b

b = 7

Answer 3

Let's solve the given equations step by step:

Equation 1: 3*a - (40 - 13) = 3

First, simplify the expression inside the parentheses:

3a - (40 - 13) = 3 3a - 27 = 3

Next, add 27 to both sides of the equation to isolate the variable "a":

3a - 27 + 27 = 3 + 27 3a = 30

Finally, divide both sides of the equation by 3 to solve for "a":

3*a/3 = 30/3 a = 10

Therefore, the value of "a" in the equation is 10.

Equation 2: (98 - 56) : b = 24 : 4

First, simplify both sides of the equation:

(98 - 56) : b = 24 : 4 42 : b = 24 : 4

Next, we can write the equation using cross multiplication:

42 * 4 = b * 24

Solve for "b" by dividing both sides of the equation by 24:

(42 * 4) / 24 = b 168 / 24 = b 7 = b

Therefore, the value of "b" in the equation is 7.
