Answer:
the value of a is 4 ÷ 7
Step-by-step explanation:
The computation of the value of a is shown below:
Given that the following equation
|7|x| - 4 = a
Based on the above equation
As we can see that the modulus is applied
So after removing the modulus, it would be
7x - 4 = a
7x = 4
x = 4 ÷ 7
Hence, the value of a is 4 ÷ 7
The same would be relevant
Answer:

<em></em>
<em></em>
Step-by-step explanation:
Given

per hour
Required
Determine the expression for the cost in x hours
Represent the cost with y
y is calculated using the following expression

Where x represent the number of hours.
Substitute values for the base amount of bike and the additional cost per hour


<em>So, the expression to determine the cost of bike in x hours is: </em>
<em></em>
that would be four hours.
12x3=36
1 hour 20 minutes x3= 4 hours
