4 times a number added to 7 times the number equals 33
The number is 20.
x = -.25
N = the number It's [ 7N + (N+8) ]
Let n be the number. Then what you're asking for is 6n+(n+7).
When 3 is added 5 times to a number the result is 15 if the number is 0, otherwise this is not true. However, the amount added to the number is always 15. Let's say the variable x is our number and y is the result, then x+3+3+3+3+3=y. You can add all the 3's together now. So you have x+15=y. Now if the starting number is 0, you have 15=y, so the result is 15.
using algebra, this can be written as 7(2N+2) 14n+14. 14 times the number plus 14.
Include the result of of the multiplication to produce the sentence, "Seven times eight equals fifty six."
If: 6x+8 = 32 Then: x = 4
If: 2x+5 = 45 then the value of x works out as 20
It is 5 because 1638 times 6 = 9828
When 3 times a number is decreased by 4 the result is 17. what is the number?
We'll use "n" to represent "number." First, "eight times a number" means the number is multiplied by eight. 8n Then, seven is added to 8n. 8n + 7 Also, you can display it like this if it helps: (8 x n) + 7
Suppose the number is x. Then 4x + 7x = 44 ie 11 x = 44 Divide both sides by 11 to give x = 4.
If seven times a number results in 35, then six times a number would be five less.
