Math Question: If 3% of 1290 is added to 1290, then 40% of the result is subtracted, what is the final value? Math

To find the final value, we start by calculating 3% of 1290, which is (3/100) * 1290 = 38.7. Adding this to 1290 gives us 1328.7. Now, to find 40% of this result, we calculate (40/100) * 1328.7 = 531.48. Subtracting this value from 1328.7 gives us the final answer: 1328.7 - 531.48 = 797.22. Therefore, the final value after adding 3% and subtracting 40% from 1290 is equal to 797.22.

Question: Solve the following equation for x: (3x + 5) / 2 - (2x - 10) / 3 = 1290

To solve the equation, we will multiply both sides by the least common multiple (LCM) of the denominators (which is 6) to eliminate the fractions. First, we multiply each term by 6: 6 * [(3x + 5) / 2] - 6 * [(2x - 10) / 3] = 6 * 1290 Simplifying, we get: 3(3x + 5) - 2(2x - 10) = 7740 9x + 15 - 4x + 20 = 7740 5x + 35 = 7740 Next, we isolate the variable: 5x = 7740 - 35 5x = 7705 Finally, divide both sides by 5: x = 7705 / 5 x = 1541 Therefore, the solution to the equation (3x + 5) / 2 - (2x - 10) / 3 = 1290 is x = 1541.

Math question: Bob has $1290. He spends $30 each day. How many days will it take for him to run out of money?

If Bob spends $30 each day out of his $1290, we divide 1290 by 30 to find out how many days it will last. 1290 ÷ 30 = 43. Therefore, it will take Bob 43 days to run out of money if he spends $30 each day.
