Explanation:
_______________________________________________________
Set up a ratio as a fraction:
_______________________________________________________
8/3 = 320/x ;
_______________________________________________________
Cross-multiply:
_____________________________________________________
8x = 3 * 320 ;
8x = 960 ;
Divide each side of the equation by "8" ;
to isolate "x" on one side of the equation ; and to solve for "x" ;
______________________________________________________
8x / 8 = 960 / 8 ;
to get: x = 120 .
The answer is: [A]: " 120 ft² " .

Answer:
option 1
Step-by-step explanation:
We have that
<span>y=2x-1
and
Y=2x+3
the two lines are parallel
because the slopes are the same
m=2
we know that
</span>If two lines are parallel<span>, then they will never intersect
</span><span>
therefore
the answer is the option
</span><span>D no solution</span><span>

4x +28 and 68 are vertical angles and are equal.
Set them to equal each other to solve for x:
4x +28 = 68
Subtract 28 from each side:
4x = 40
Divide both sides by 4:
x = 40/4
x = 10
