The population of the bacteria 96 minutes from now is 12.
You can cross multiply
-11(-9) x *( 1)
99=1x
99=x
the answer is 99=x
The answer would be D.
you would start by choosing one of the variables to eliminate, i chose to eliminate X first. in order to eliminate X, i had to multiply the second equation by -2. X then cancelled out, and i solved for the Y the same way you would a 1 step equation. Y=-4
I then took the first original equations, plugged Y in, and solved for X. X=3.
Hope this helps!
Owen. studied more. Maya studying 0.5 that length means she studied only half of Owen's time. This means Maya studied 45 minutes. 90 is greater than 45.
