Hi there...
2( x - 6) < 1/2(12x - 8)
2x - 12 < (12x- 8)/2
2x - 12 < 6x - 4
2x - 6x < -4 + 12
-4x < 8
Divide both sides by -4
-4x/-4 < 8/-4
x > - 2
$20, so 40-20= 20 (half of 40) so you could also say that the apples are 50% off
Answer:
143 Minutes or 2 hours and 23 Minutes
Step-by-step explanation:
You have to find the rate at which she is typing and spell checking the pages
Ex//
26 minutes= 14 pages ----- simpllify to 13 Minutes= 7 pages
----you want to know how long it takes to do 77 pages---
77 can be found by multiplying 7 x11 so do the same with 23 (23x11)
** don't forget the unit!**
0.1y = 3x^2
divide each side by 0.1
y = 3x^2/0.1
factor the right side to get y = 30x^2
this can't be written in the form y = kx so y does not vary directly with x
so there is no constant of variation.
Answer:
16000 bacteria after 60 days
Step-by-step explanation:
60 divided by 12 = 5
500 x 2= 1000
1000 x 2 = 2000
2000 x 2 = 4000
4000 x 2 = 8000
8000 x 2 = 16000
