Answer 1

225:5-37=45-37=8; // 84х9:18=756:18=42;// №2 Х+(1690-480)=3340; Х+1210=3340; х=3340-1210; Х=2130- Проверка: 2130+1210=3340;;3340=3340

Answer 2

Calculation 1: 225 divided by 5 minus 37

To calculate 225 divided by 5 minus 37, we need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

Let's break down the calculation step by step:

1. Divide 225 by 5: 225 ÷ 5 = 45 2. Subtract 37 from the result: 45 - 37 = 8

Therefore, the result of the calculation 225 divided by 5 minus 37 is 8.

Calculation 2: 84 multiplied by 9 divided by 18

To calculate 84 multiplied by 9 divided by 18, we again need to follow the order of operations.

Let's break down the calculation step by step:

1. Multiply 84 by 9: 84 × 9 = 756 2. Divide the result by 18: 756 ÷ 18 = 42

Therefore, the result of the calculation 84 multiplied by 9 divided by 18 is 42.

Equation with Verification: X = (1690 - 480) equals 3340

To solve the equation X = (1690 - 480) and verify the solution, we substitute the value of X back into the equation and check if both sides are equal.

Let's solve the equation step by step:

1. Subtract 480 from 1690: 1690 - 480 = 1210 2. Substitute X with 1210 in the equation: 1210 = 3340

Now, let's verify the solution:

1. Subtract 480 from 1690: 1690 - 480 = 1210 2. Check if 1210 equals 3340: 1210 ≠ 3340

Since the left side of the equation (1210) is not equal to the right side (3340), the solution X = 1210 is incorrect.

Therefore, there is no solution to the equation X = (1690 - 480) equals 3340.
