X^2 - 3x = 3
(x - 1.5)^2 - 2.25 = 3
(x - 1.5) = +/- sqrt 5.25

x = 1.5 +/- sqrt5.25

x = -0.79, 3.79 to nearest hundredth

If 3x-7=5t what is 6t?

Amiraneli [1.4K]

So one easy way is
divide both sides by 5
$\frac{3x-7}{5}$ =t
multiply both sides by 6

$\frac{6}{1}$ times $\frac{(3x-7)}{5}$ =6 times t or

$\frac{6 times (3x-7)}{5}$ =6t or
$\frac{18x-42}{5}$ =6t
