Answer:
a) 370 yards
b) 196.6 yards
c) z ∈ (0, 380)
d) The variable z assumes infinite values, since there are infinite position numbers from z = 0 yards to z = 320 yards.
Step-by-step explanation:
a) (380 - 10
) yards = 370 yards
b) (380 - 183.4) yards = 196.6 yards
c) and d)
This situation can be described as a horizontal line that begins at point
P₁ = 0 yards (Christy's house) and ends at P₂ = 320 yards (Bus stop). Where a is the varying distance from her house, which can be calculated in the following way:
z = Final Position - Initial Position
As Christy walks from her house to the bus stop, the variable z assumes infinite values, since there are infinite position numbers from z = 0 yards to z = 320 yards.

Answer:
For any mathematical expression follow the BODMAS rule which states that we should calculate the Brackets first (2 + 4 = 6), then the Orders (52 = 25), then any Division or Multiplication (3 x 6 (the answer to the brackets) = 18), and finally any Addition or Subtraction (18 + 25 = 43).
Step-by-step explanation:
(5+4) × 5 + 3.3
Bracket open = 9
Since there is no division, so multiply 9×5, which is 45
Then add, 45+3.3
Answer= 48.3
