Answer:

$x \leqslant 3$

Third answer is correct.

Step-by-step explanation:

$2(4 + 2x) \geqslant 5x + 5 \\ 8 + 4x \geqslant 5x + 5 \\ 8 - 5 \geqslant 5x - 4x \\ = 3 \geqslant x$

hope this helps you

Answer:

$x\le 3$

Step-by-step explanation:

$2(4+2x)\ge 5x+5$

$2(4)+2(2x)\ge 5x+5$

$8+4x\ge 5x+5$

$8-5\ge 5x-4x$

$3\ge 1x$

$x\le 3$

As part of Kayla's exercise program,she either runs 6miles/day or rides her bike 10 miles/day.Her new goal is to cover a minimum

poizon [28]

6(15) + 10b > = 200
90 + 10b > = 200
10b > = 200 - 90
10b > = 110
b > = 110/10
b > = 11

so she can do 15 days of running plus 11 days of biking....which totals 26 days

Temka [501]

Answer:

D. 5$

Step-by-step explanation:

So, since he wants to save up the whole year, that would be 365 days. And, he wants to collect some money after then end of each <em>week</em>, and a week is 7 days, so you'd divide 365/7. This would give you about 52 weeks he'll set aside money for United Way. Therefore, you'd divide $260/52 weeks, to get a total of $5 each week.

A sample of bacteria is being eradicated by an experimental procedure. The population is following a pattern of exponential deca

77julia77 [94]

Answer:

There will be 50 bacteria remaining after 28 minutes.

Step-by-step explanation:

The exponential decay equation is

$N=N_0e^{-rt}$

N= Number of bacteria after t minutes.

$N_0$ = Initial number of bacteria when t=0.

r= Rate of decay per minute

t= time is in minute.

The sample begins with 500 bacteria and after 11 minutes there are 200 bacteria.

N=200

$N_0$ = 500

t=11 minutes

r=?

$N=N_0e^{-rt}$

$\therefore 200=500e^{-11r}$

$\Rightarrow e^{-11r}=\frac{200}{500}$

Taking ln both sides

$\Rightarrow ln| e^{-11r}|=ln|\frac{2}{5}|$

$\Rightarrow {-11r}=ln|\frac{2}{5}|$

$\Rightarrow r}=\frac{ln|\frac{2}{5}|}{-11}$

To find the time when there will be 50 bacteria remaining, we plug N=50, $N_0$ = 500 and $r}=\frac{ln|\frac{2}{5}|}{-11}$ in exponential decay equation.
