That gives you 11/8 of the number.
8z + 5
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
8+3*x
That gives you 11/8 of the number.
3n + 8
Three.
8z + 5
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.
