x = 2(x+2) + 3(x-1) = 3x + 7
2x + 4 + 3x -3 = 3x + 7
2x + 3x - 3x = 7 - 4 + 3
2x = 6
x = 3
NOT SIMILAR
Explanation:
Look at the bottom of the triangle, the bottom of the left one is shorter than the right making the triangles not similar.
Let
x------> the number of multiple choice question
y------> the number of free response question
we know that
-----> equation A
-----> equation B
Substitute equation B in equation A
Find the value of x
therefore
the answer is
the number of multiple choice question are
the number of free response question are
