Subtract 5 from both sides.
Subtract 8n from both sides.
Divide both sides by -9 to solve for n.
The value of n is
-4/9.
Given that <span>Helen wants to find the surface area of the solid pictured on the left, so she constructs a net of the solid, pictured on the right. The statement that best describes her work is:
</span><span>Helen’s net is incorrect because she forgot to include the shared rectangular face where the upper and lower solids are joined together. </span>
Intersection is what point satisfies both equaitons
divide second equation by 2 for simplificy
2x-y=8
oh dear, we got the same equation
therefor they are the same line
infinitely many points
anywhere on the line 2x-y=8
some points are
(4,0)
(5,2)
anywhere on the line 2x-y=8
1/5x2=2/10 Here is the answer: Nathan spent 2/10 of his allowance! I got it from my work at the beginning: 1/5 x 2 = 2/10.
