Question

А:15=54:(6*3)= 55*х+710=810=300-х=42*2+50=​

Answer 1

Пошаговое объяснение:
A÷15=54÷(6×3),
А:15=54:18
А:15=3
А=15*3
А=45
55×x+710=820,
55х=820-710
55х=110
Х=110:55
Х=2
300-x=42×2+50
300-х=84+50
Х=300-84-50
Х=166

Answer 2

It seems like you've presented a series of equations and expressions. Let's break them down step by step:

1. A:15 = 54:(6*3) First, solve the expression within the parentheses: 6 * 3 = 18 So, the equation becomes: A:15 = 54:18

   Now, calculate the division on the right side: 54 ÷ 18 = 3

   So, A:15 = 3.

2. 55 * x + 710 = 810 Subtract 710 from both sides of the equation: 55 * x = 810 - 710 55 * x = 100

   Now, solve for x by dividing both sides by 55: x = 100 / 55 x = 20/11

3. 300 - x = 42 * 2 + 50 First, calculate the right side of the equation: 42 * 2 = 84 84 + 50 = 134

   Now, subtract 134 from 300 to solve for x: 300 - 134 = 166

   So, x = 166.

Your values for A and x are as follows: A = 3 x ≈ 20/11
