Question

45 • 2• y = 90045 · 2 + b = 900a – 45 • 2 = 900​

Answer 1

Ответ:

у=10.  b=810.  а=990

Пошаговое объяснение:

1) 45*2*у=900

90у=900

у= 900:90

у=10

2) 45*2+b = 900

90+b = 900

 b= 900-90

 b=810

3) а - 45*2 =900

а - 90=900

а= 900+90

а=990

Answer 2

Ответ:

Пошаговое объяснение:

90y = 900

y = 10

90 + b = 900

b = 900 - 90

b = 910

a - 90 = 900

a = 900 + 90

a = 990

Answer 3

To solve the equations, let's break them down step by step:

1. 45 • 2 • y = 900 Simplifying the left side of the equation: 90y = 900 Divide both sides of the equation by 90: y = 10

2. 90045 · 2 + b = 900a – 45 • 2 Simplifying the left side of the equation: 180090 + b = 900a – 90 Rearranging the terms: b + 180090 = 900a – 90 Moving the constant term to the right side: b = 900a – 90 – 180090 Simplifying: b = 900a – 180180

3. 900a – 45 • 2 = 900 Simplifying the left side of the equation: 900a – 90 = 900 Moving the constant term to the right side: 900a = 900 + 90 900a = 990 Divide both sides of the equation by 900: a = 990/900 Simplifying: a = 11/10 or a = 1.1

Therefore, the solutions to the equations are: a = 1.1 b = 900a – 180180 (substitute the value of a) b = 900(1.1) – 180180 b = 990 – 180180 b = -179190 y = 10
