It means not to get too invested in details or to become so invested in something that you can’t focus on anything else.
Answer:

Step-by-step explanation:
When you reflect a point (x, y) in the y-axis, the y-coordinate remains the same, but the x-coordinate gets the opposite sign. Thus,
E (8,4) ⟶ E' (-8,4)
F (-16,-8) ⟶ F' (16,-8)
G (24,-16) ⟶ G' (-24,-16)

The figure EFG and its reflection E'F'G' are shown in the diagram below.
If there are 20 groups of 10, then there are 200 pencils. Subtract 200 and 137 to get the number of dull pencils.
X = 0.882
y = 0.647
seems to be a good approximation of the solution.
