$1. \: = > 4( - 7) \\ = 4 \times - 7 \\ = - 28$

$3. \: = > 9( - 12) \\ = 9 \times - 12 \\ = - 108$

$4. \: = > - 6( - 8.75) \\ = 6 \times 8.75 \\ = 52.5$

$5. = > 27( - 3) \\ = 27 \times - 3 \\ = - 81$

$7. \: = > - 55(0) \\ - 55 \times 0 \\ = 0$

$8. \: = > ( - 7)( - 7.25) \\ = 7 \times 7.25 \\ = 50.75$

$11. \: = > ( - 1) {}^{4} \\ = 1 {}^{4} \\ = 1$

$13. = > 42 \div ( - 7) \\ = - (42 \div 7) \\ = - 6$

$15. = > - 9 \div 3 \\ = - (9 \div 3) \\ = - 3$

It takes Ernesto 3 minutes to jog a lap around the school track. How many laps can Ernesto complete in 15 minutes?

OLEGan [10]

Answer:

5 laps

Step-by-step explanation:

We can use ratios to solve

3 minutes 15 minutes

----------------- = ------------------------

1 lap x laps

Using cross products

3x = 15

Divide each side by 3

3x/3 = 15/3

x = 5

He can do 5 laps

How to solve this???<br> e^(2x) - e^x = 6

Ray Of Light [21]

$e^{2x}-e^x=6$
$(e^x)^2-e^x-6=0$
$(e^x-3)(e^x+2)=0$

$e^x=3$
$e^x=-2$

therefore $x=\ln3$ and $x=\ln-2$
because $\ln-2$ doesn't exist, the only solution to your equation is $x=\ln3$
