It is 9.25 gallons, I hope this helps :)
(6x + 8) / (4x + 4)
(3x +4) 2(x 1)
2(3x + 4) 4(x +1)
Answer:
<h2>A) a - 1 and B) a + 2</h2>
Step-by-step explanation:
The equation is y = 20(1.40)^x
where x is the number of days and y is the future amount after x days go by
The 1.40 is from the fact that 1+r = 1+0.40 = 1.40, where r is the decimal form of 40%, so r = 0.40
-----------------------------
Plug in x = 7 to get
y = 20(1.40)^x
y = 20(1.40)^7
y = 210.827008
y = 211
We round to the nearest whole number since it doesn't make much sense to have a fractional portion of an algae. After 7 days, there are about <u>211</u> algae.
