First we rearrange to make x = a number
9x + 27 = 27 <- subtract 27 from both sides
9x = 0
When x ='s a number there is 1 solution.
The answer is 1 solution.
Here are some examples to distinguish how many solutions something has:
> No solution, 0 = 12
> One solution, Y = 6
> Infinite solutions, 0 = 0
Please give me brainliest answer if I helped!

Use pathagoream theorem. You get the equation: 10^2=6^2+x^2 then solve and simplify to get x=8 So no Tom is not afraid of the heights
The class has 28 student. One group has four more students so surat 4 from 28. 28-4=24 since one of the groups have twice as many students as the other divide 24 by 3. 24 / 3 = 8. It says 1 group has for more than twice the other group so that would mean 2/3 of 24 and 4 would be the answer 16+4=20. The first group had 8 students, the other group has 20 students.
Answer:
16. 3
17. 12 / 7
18. 24 / 5 ( or ) 4.8
Step-by-step explanation:
16.
2 / ( x - 1 ) = 1
2 = x - 1
x = 2 + 1
x = 3
17.
( x / 3 ) + ( x / 4 ) = 1
LCM ( 3, 4 ) = 12
x / 3 = 4x / 12
x / 4 = 3x / 12
( x / 3 ) + ( x / 4 ) = 1
( 4x / 12 ) + ( 3x + 12 ) = 1
( 4x + 3x ) / 12 = 1
7x / 12 = 1
7x = 12
x = 12 / 7
18.
( x / 3 ) + ( x / 2 ) = 4
LCM ( 3, 2 ) = 6
x / 3 = 2x / 6
x / 2 = 3x / 6
( x / 3 ) + ( x / 2 ) = 4
( 2x / 6 ) + ( 3x / 6 ) = 4
( 2x + 3x ) / 6 = 4
5x / 6 = 4
5x = 24
x = 24 / 5
( or )
x = 4.8
