In customary units, the length of a car would be in feet.
6x - 4y = 8...solve for x
6x = 4y + 8
x = (4/6)y + 8/6
x = 2/3y + 4/3 <==
Answer:
D
11 - x <_ 18
11 - 7 <_ 18
4 <_ 18 (4 is less than or equal to 18)
40° is right I believe so
Since you asked how to solve this, I will put the answer at the bottom.
You might not think the same way as I but I think in steps.
<h3>(1) Calculate how many times the bacteria divide in eleven hours</h3>
The bacteria divide every 20 minutes, and will therefore divide three times every hour, 60/20 = 3.
If the bacteria grow for eleven hours, each bacterium will divide 3 times per hour × 11 hours = 33 times.
<h3>(2) Add the orginial size of bacteria into the equation</h3>
(This part is edited)
(orginial size)*2^number of divisions
10*
