Question

A:13+47=54 96:(78:х)=16

Answer 1

 а: 13 +47= 54
а:13=54-47
а:13= 8
а= 13*8
а= 104

96: (78:х)=16
78:х=96:16
78:х= 6
х=78:6
х=13

Answer 2

А:13+47=54               96:(78:х)=16
А:13=54-47                 78:х=96:16
А:13=7                         78:х=6
А=7умн.13                    х=78:6
А=91                              х=13

Answer 3

Let's solve the equations step by step:

1. A: 13 + 47 = 60 (not 54) The sum of 13 and 47 is 60, not 54.

2. 96 : (78 : x) = 16 To solve this equation, we need to work from the inside out, following the order of operations (parentheses, then division, and finally multiplication or addition/subtraction).

   First, let's simplify the expression inside the parentheses: 78 : x

   Since we don't know the value of x, we can't simplify this further.

   Now, substitute 78 : x back into the original equation: 96 : (78 : x)

   Using the property of division, we can rewrite this as: 96 * (x : 78)

   Now we have: 96 * (x : 78) = 16

   To solve for x, divide both sides of the equation by 96: (96 * (x : 78)) / 96 = 16 / 96

   Simplifying further: x : 78 = 16 / 96

   To solve for x, multiply both sides by 78: ((x : 78) * 78) = (16 / 96) * 78

   The 78 on the left side cancels out, and we're left with: x = (16 / 96) * 78

   Evaluating the right side of the equation: x = (1/6) * 78

   Simplifying the fraction: x = 13

   Therefore, the value of x that satisfies the equation is 13.

In summary:

1. A: 13 + 47 = 60
2. x = 13
