Answer:
Step-by-step explanation:
I'm going to guess that 1/2 the size means the sides are 1/2 the size.
Square 1 has an area of 24. The sides are s, so the area is found by using s^2
The second square is made from sides that are 1/2 s
Area = 1/2 s * 1/2 s
Area = 1/4 s^2
Area 1 / area 2 = 24 / x^2 = s^2 / 1/4 s^2 = 1/0.25
the distance between 2 positive points on a line, would come from subtracting the 2 numbers
9.4 - 1.8 = 7.6 ( distance)
Subtract 2(first equation) from the second, and 3(first equation) from the third to eliminate <em>x</em> :
(2<em>x</em> + 3<em>y</em> + <em>z</em>) - 2(<em>x</em> + <em>y</em> + <em>z</em>) = 16 - 2*9
<em>y</em> - <em>z</em> = -2
(3<em>x</em> - 4<em>y</em> + 2<em>z</em>) - 3(<em>x</em> + <em>y</em> + <em>z</em>) = 1 - 3*9
-7<em>y</em> - <em>z</em> = -26
Now subtract either equation with <em>y</em> and <em>z</em> from the other to eliminate <em>z</em>. If we take the first from the second, we get
(-7<em>y</em> - <em>z</em>) - (<em>y</em> - <em>z</em>) = -26 - (-2)
-8<em>y</em> = -24
<em>y</em> = 3
Then
<em>y</em> - <em>z</em> = 3 - <em>z</em> = -2
<em>z</em> = 5
And lastly,
<em>x</em> + <em>y</em> + <em>z</em> = <em>x</em> + 3 + 5 = 9
<em>x</em> = 1
