20. Method: call the unknown number n. From the problem statement, 3n + 15 = 75, or 3n = 75 -15 = 60 and n = 60/3 = 20.
3 times 3 = 9 plus the number 3 = 12.
( 5 + 3x )
Three times nine plus a number.
5
6 or -8
7
3 times 3 = 9 plus the number 3 = 12.
If you mean 3x+10 = 5x then the value of x works out as 5
3x+5x
A + 2a = 3a
A number is x squared plus forty four is equal to the number x to the fourth power times three?
3(n+5) three times n plus five n represents the unknown number
( 5 + 3x )
So 5 must be the other two times the number which means the number is 2.5.
4
it means 8+3x 8 increased (plus) three times a number (3x) x is an unknown number so it is often called a number
Three times nine plus a number.
