Write an equation. Let x be the unknown number.

HACTEHA [7]

Since x is our unknown number, on one side of our equation we will have the "Subtracting two times a number from 10", and on the other will be -3. So,
-3=10-2x

Semi perimeter:-

$\\ \rm\rightarrowtail s=\dfrac{a+b+c}{2}$

$\\ \rm\rightarrowtail s=\dfrac{1.8+2.4+3}{2}$

$\\ \rm\rightarrowtail s=\dfrac{7.2}{2}=3.6cm$

Apply heron s formula

Area:-

$\\ \rm\rightarrowtail \sqrt{s(s-a)(s-b)(s-c)}$

$\\ \rm\rightarrowtail \sqrt{3.6(3.6-1.8)(3.6-3)(3.6-2.4)}$

$\\ \rm\rightarrowtail \sqrt{3.6(1.8)(0.6)(1.2)}$

$\\ \rm\rightarrowtail \sqrt{4.6656}$

$\\ \rm\rightarrowtail 2.16cm^2$

Which statements are true about the ordered pair (−1, 5) and the system of equations?

{x+y=4 x−y=−6

Select each correct answer.

The ordered pair (−1, 5) is a solution to the first equation because it makes the first equation true.The ordered pair (−1, 5) is a solution to the second equation because it makes the second equation true.The ordered pair (−1, 5) is not a solution to the system because it makes at least one of the equations false.The ordered pair (−1, 5) is a solution to the system because it makes both
