it means 8+3x
8 increased (plus) three times a number (3x) x is an unknown number so it is often called a number
That gives you 11/8 of the number.
So 25% of the new value is the newly-added 8. Therefore the original value is three times that, i.e. 24. This means that three 8s plus the other 8 - i.e. four 8s - equals 32.
7x - 8 = 3x + 4 4x - 8 = 4 4x = 12 x = 3 Check it. 21 - 8 = 9 + 4 It checks.
3n>8
It is: 3x = 2x+8 and the value of x is 8
8+3*x
That gives you 11/8 of the number.
3n + 8
Three.
If the number is a multiple of 8 or greater than 8. or divide by two, three times
3 x 8
So 25% of the new value is the newly-added 8. Therefore the original value is three times that, i.e. 24. This means that three 8s plus the other 8 - i.e. four 8s - equals 32.
8
7x - 8 = 3x + 4 4x - 8 = 4 4x = 12 x = 3 Check it. 21 - 8 = 9 + 4 It checks.
3n>8
A number multiplied by itself three times is a cube number. Examples are 2 x 2 x 2 or 23 = 8.
If ten times the number n decreased by 13 is equal to the square of the same number n increased by 3, then the value of n is either 8 or 2.
