4x / (2 + 4) = 60
Therefore, 4x = 60 x 6 = 360
x = 360/4
x = 90
Call your number some variable, for example, "n". Twice the number would be 2n, adding four to that you get 2n + 4, and six times all that is 6(2n + 4), which is the same as 12n + 24.
The sum of number and four times a number is 25 write in algebraic expression
90
4x+5x
It is the sum of the number which is then divided by 2.
4N + 8
Call your number some variable, for example, "n". Twice the number would be 2n, adding four to that you get 2n + 4, and six times all that is 6(2n + 4), which is the same as 12n + 24.
The sum of number and four times a number is 25 write in algebraic expression

If your number is 4 times ?, and the sum is 40, your problem would be 40 divided by 4. You'd get 10.
2x+4y
4x+5x
6x + 4 = 5x x = -4
the sum of the elements divided by the number of elements is the average
It is the sum of the number which is then divided by 2.
Suppose the number is x. The sum of the number and two is x+2 Four times the sum is 4(x+2) The number times 8 is 8x 24 less than the number times 8 is 8x-24 4(x+2) = 8x-24 4x+8=8x-24 so 4x = 32 and x = 8
The mean of a series is equal to the sum divided by the number of items in the series. So, mean = sum/number, which means the sum is equal to the mean times the number. In this case, the sum is 3573.
