Answer:
cost of journey of 25 miles = £ 17.5
Step-by-step explanation:
Base on the equation the cost of the journey can be represented as
C = 0.5n + 5
where
C = cost in £
n = number miles covered
To calculate the cost of a journey that is 25 miles we have to insert the value of n as 25 in the equation. Therefore,
C = 0.5n + 5
n = 25
C = 0.5(25) + 5
C = 12.5 + 5
C = £ 17.5
cost of journey of 25 miles = £ 17.5
5 a niceeeee jooooooobbbbbn
Answer:
-5/2
Step-by-step explanation:
2x + 9 = 4
2x = -5
x = -5/2
Write the decimal number as a fraction
(over 1)
9.85 = 9.85 / 1
Multiplying by 1 to eliminate 2 decimal places
we multiply top and bottom by 2 10's
Numerator = 9.85 × 10 × 10 = 985
Denominator = 1 × 10 × 10 = 100
Numerator / Denominator = 985 / 100
Simplifying our fraction
= 985/100
= 197/20
= 9 17/20
