Math question: If a number is increased by 5 and then multiplied by 4, the result is 172. What is the number?

Let's represent the unknown number as x. According to the given condition, the equation can be formed as (x + 5) * 4 = 172. To solve, we can multiply 4 with x and 5 resulting in 4x + 20 = 172. By subtracting 20 from both sides, we get 4x = 152. Finally, dividing both sides by 4 gives us x = 38. Therefore, the number is 38.

Math question: If you divide a number by 4, subtract 3, multiply by 2, add 8, and finally divide by 2, what is the result if the number is 32?

To solve the expression, we can follow the given operations step by step. Starting with the number 32: 1. Divide by 4: 32 ÷ 4 = 8 2. Subtract 3: 8 - 3 = 5 3. Multiply by 2: 5 × 2 = 10 4. Add 8: 10 + 8 = 18 5. Finally, divide by 2: 18 ÷ 2 = 9 Thus, if the number is 32, following the given operations yields a result of 9.

Math Question: What is the sum of the first 32 even natural numbers?

The first even natural number is 2, and the last one is 64 (32 multiplied by 2). Hence, the sum can be found by using the formula for the sum of an arithmetic series: S = (n/2)(a + l), where S is the sum, n is the number of terms, a is the first term, and l is the last term. Substituting values, S = (32/2)(2 + 64) = 16(66) = 1056. Therefore, the sum of the first 32 even natural numbers is 1056.
