Answer:
X>3
Step-by-step explanation:
-2.5x +5 < -2.5
-2.5x < -2.5-5
-2.5x< -7.5
X> -7.5/-2.5
X>3
Equation for a is c=.65p
for two pounds the cost would be 1.30
part b is c=.65-.05p

Answer:
x = y / 3.2
Step-by-step explanation:
Given:
y = 3.2x
Where
y = cost for a taxi ride during peak hours (in dollars)
x = cost for a taxi ride during off-peak hours (in dollars)
Solve the equation for x.
y = 3.2x
Divide both sides by 3.2
y / 3.2 = 3.2x / 3.2
y / 3.2 = x
x = y / 3.2
This means,
Cost for a taxi ride during off-peak hours (in dollars) = Cost for a taxi ride during peak hours (in dollars) / 3.2
Answer:
3x - 4 = 12
3x = 12 + 4
3x = 16 (divide both sides by 3 to get x)
3x/3 = 16/3
x = 5.333.......
