To express "two less than five times a number," we can use a variable, say ( x ), to represent the number. The phrase translates to the mathematical expression ( 5x - 2 ). This indicates that you first multiply the number by five and then subtract two from the result.
Assuming the number is n; then: 2n + (6n + 5) = 8n + 5 That means five added to eight times the number
5x - 2
Five times a number is 200 what is the number
The five on the left is ten times the five on the right.
Assuming that you can use each number multiple times, 3125, because there are five options for the first number, five for the second, and so on to reach five. Then, five times five times five times five times five, or five to the fifth power, equals 3125. Were you only able to use each number once, the answer would be 120 based on the same principle. There would be five options for the first number, four remaining options for the second, three for the third, two for the fourth, and then one for the fifth. Then, as with the first, five times four times three times two (times one, but that really isn't necessary) results in 120.

the number is 3 because 3 times 5 is 15 plus 2 is 17
There are two consecutive odd numbers such that five times the smaller plus twice the greater is 25. What is the smaller number?
They are 4 and 7.
