Total distance = 20 km = 20 000 m
walk = 800 m
cycle = 20 000 - 800 = 19 200m
percentage of the journey =

x 100% = 96%
Answer:
Step-by-step explanation:
If Lois is 4 times as old as her son and we don't know how old the son is, the son's age is x and his mother's age is 4x (4 times the son's age). The word sum means to add, so the equation for this is
x + 4x = 40
Answer:
Good Luck!
Step-by-step explanation:
Answer:
Step-by-step explanation:
m = -4 ; (x₁ , y₁) = (2, -7)
Point slope form: y - y₁ = m(x - x₁)
y - [-7] = (-4)(x - 2)
y + 7 =(-4)(x - 2)
Because 4 x 3 is 12 4 + 4+ 4+ = 12
