Question

А-250*3=500:10 950:b=120-115​

Answer 1

Ответ:

Пошаговое объяснение:

а-250*3=500:10

а - 750 = 50

а = 750 + 50

а = 800

800 - 750 = 50 - верно

950:b=120-115​

950 : в = 5

в = 950 : 5

в = 190

950 : 190 = 5 - верно

Answer 2

Let's solve each of these equations step by step:

1. A - 250 * 3 = 500 ÷ 10

   First, perform the multiplication on the left side of the equation:

   A - 750 = 500 ÷ 10

   Now, simplify the division on the right side:

   A - 750 = 50

   Finally, add 750 to both sides to solve for A:

   A = 800

2. 950 : b = 120 - 115

   Start by subtracting the numbers on the right side of the equation:

   950 : b = 5

   To solve for 'b', you can cross-multiply:

   950 * 1 = b * 5

   Simplify:

   b = 950 ÷ 5

   b = 190

So, the solutions are:

1. A = 800
2. b = 190
