18. 0.796 + 13 = 13.796 (the 13 is a whole number, so just put it in front of the decimal)

19. 15.63 + 24.36 = 39.99 (1+2=3 ; 5+4=9 ; 6+3=9 ; 3+6=9)

20. 19.86 - 4.94 = 14.92

21. 82 - 67.18 = 15.18 (again, whole number, there's no decimals to subtract, so leave them be)

22. 14.39 - 12.16 = 2.23 (1-1=0 ; 4-2=2 ; 3-1=2 ; 9-6=3)

Hi,

The equation: (3^6)^2 x (3^0)

Multiply:

=(729^2)(3^0)

=531441 (3^0)

Simplify:

=(531441) (1)

Multiply again:

=531441 or D. (3^12)

Have a great day!

3. How many solutions does the system of equations have? 2x=-10y+ 6 and x+5y=3

ozzi

Answer:

<h2>3. Infinitely many</h2>

Step-by-step explanation:

$\left\{\begin{array}{ccc}ax+by=c\\dx+ey=f\end{array}\right\\\\(1)\\\text{if}\ a=d,\ b=e,\ c=f,\ \text{then the system of equations has infinitely many solutions}\\Example:\\\left\{\begin{array}{ccc}2x-3y=5\\2x-3y=5\end{array}\right\\(2)\\\text{if}\ a=d,\ b=e,\ c\neq f,\ \text{then the system of equations has no solution}\\Example:\\\left\{\begin{array}{ccc}2x-3y=5\\2x-3y=-5\end{array}\right$

$(3)\\\text{if}\ a\neq d\ \text{or}\ b\neq e,\ \text{then the system of equations has infinitely many solutions}\\Example:\\\left\{\begin{array}{ccc}x-3y=5\\2x-3y=5\end{array}\right$

$\text{We have:}\\\\\left\{\begin{array}{ccc}2x=-10y+6&\text{add 10y to both sides}\\x+5y=3\end{array}\right\\\left\{\begin{array}{ccc}2x+10y=6&\text{divide both sides by 2}\\x+5y=3\end{array}\right\\\left\{\begin{array}{ccc}x+5y=3\\x+5y=3\end{array}\right$

Frank is in an airplane flying at 14,080 ft above sea level. He wants to land the airplane on a runway that is 22 ft below sea l

Blababa [14]

The total distance between the airplane and the runway is 14102 ft.

The total height distance between the airplane and the runway can be solved through the equation:

14,080 ft + 22ft = <span>14102 ft
</span>Since the runway is below sea level, it adds to the total distance.

Thank you for posting your question. I hope you found what you were after. Please feel free to ask me more.
