For which equation is t = 1.5 a solution? <br><br> 2t=-3 <br> t/10=15<br> 4t=6 <br> 6t=4
Dennis_Churaev [7]
To solve this, plug in 1.5 for t in each equation to see which one is true. 

1) 2(1.5) = -3 False, 2(1.5) = 3, not -3.
2) 1.5/10 = 15 Falso, 1.5/10 = .15, not 15.
3) 4(1.5) = 6 This is True, so most likely the correct answer, but it's beneficial to check them all. 
4) 6(1.5) = 4 False, 6(1.5) = 9, not 4.

Therefore, the correct answer is 4t = 6 because you can plug 1.5 in and it will remain true.
