Answer:
first he had M some unknown amount
then he had 2/3 M since he spent 1/3 M
then he spent 3/4 of the (2/3 M) so he had 1/4 of the ( 2/3M)
then he spent what was left $20 so $20 = 1/4 ( 2/3 M) now solve for M
and check by doing each step and figuring how much was spent and how much left.
<u>another</u><u> </u><u>method</u><u> </u>
let us consider the left amount be Y and total now of M dollar be X
then
Y = amount of money Nartin has left
Y = X - ( 1/3 ) ( X ) - ( 3/4 ) ( X - 1/3 X ) - 20
Y = X - 1/3 X - 3/4 X + 3/12 X - 20
Y = X - 4/12 X - 9/12 X + 3/12 X - 20
Y = X - 10/12 X - 20
Y = X - 5/6 X - 20
Y = ( 1 / 6 ) ( X ) - 20

Answer:

Step-by-step explanation:
Since one triangle is inscribed in another, the two triangles are similar. As marked in the diagram, the sides of the larger triangle are exactly two times larger than the corresponding sides of the smaller triangle.
Therefore, we have:

Since AC is marked by
:

Answer:
No, the polygons aren't similar since they don't have a constant scale factor.
