x2-b = 9
x2 = 9+b
Square root both sides:
x = the square root of (9+b)
ax-9 = b x = (b+9)/a
No. 91 never equals 9. There is no property to make that happen.
99 divided by 9 equals 11
what must you do to make the equation 81 X 9 equals 801 true.
questions like this make me want to cry......
To make 11 using three 9s, you can use the following mathematical expression: ( 9 + \frac{9}{9} ). Here, ( \frac{9}{9} ) equals 1, so the equation simplifies to ( 9 + 1 = 10 ). However, since this equals 10, we can actually use the expression ( 9 + 9/9 = 11 ) as a correct approach.
20 + (9 - 8)*2 = 22.
6+4=10
( 9+ ( 6 x 3 ) ) / 3 = 9
If x=9, x=9
7 times 9 equals 63
The square root of 9-5 equals 2.
