Answer:
9
Step-by-step explanation:
set triangles as x and squares as y
x+3y=4x+y, now plug in 6 for each triangle
6+3y=4(6)+y, solve for the weight of the squares
3y-y=24-6
2y=18
y=9, each sqaure weighs 9 units
Answer:
because all triangle's interior angles add up to 180 degrees so and angles 8 and 9 are supplementary. Angle 9 is 77 degrees.

Pages %
204 → 136%
x → 100% (her goal)
x=204*100%/136%
x=150 pages
