If 3x-8=-2 fins the value of x-6

adell [148]

Steps to solve:

3x - 8 = -2; x - 6

~Substitute

3(x - 6) = -2

~Distribute left side

3x - 18 = -2

~Add 18 to both sides

3x = 16

~Divide 3 to both sides

x = 16/3

Best of Luck!

100 +b^2=225
B^2=125
No perfect square for 125 so leave it in radical form

Step-by-step explanation:

Data

Equation y = 11.89x - 15345.2

y = 11.89 (2018) - 15345.2

2.- Multiply 11.89 by 2018

y = 23994.02 - 15345.2

3.- Subtract to find x

y = 8648.82

4.- Conclusion

There was 8649 persons in 2018.
