Answer:
<h3> -8(2x +x )/-2y = - 30</h3>
Step-by-step explanation:
x=-5, y=2 and z=0
-8(2x +x )/-2y =(-8•3x)/-2y = [-8•3(-5)] / (-2•2) = 120/(-4) =-30
You use the quadratic formula:
2x {}^{2} - 3x = 5
2x {}^{2} - 3x - 5 = 0
x = \frac{3 + - \sqrt{9 -4(2)( - 5)}}{2 \times 2}
x = \frac{3 + - \sqrt{49} }{4}
x = \frac{3 + 7}{4} \: and \: x = \frac{3 - 7}{4}
x = \frac{5}{2} \: and \: x = - 1

Answer:
ok is very easy
Step-by-step explanation:
so 1/5 of an hour is 12 mins
and 2 is 2 hrs so that 120 mins
now add 120+12=132
132 x -30 degrees
The answer to that is 132 x -30 =
-3960 sorry if its wrong and if you get a second try put -69.1150384 rad
I think sorry if you get it wrong have a good day
To make the equation easier so that you don't have to use fractions.
