Answer:
<h2>x=(y-105)/7</h2>
Step-by-step explanation:
Given that the total time taken to practice is given by the expression as
y=7(15+x)
Simplifying the expression we have
y=105+7x
Solving for x (that is making x subject of formula we have)
7x=y-105
Divide both sides by 7 we have
x=(y-105)/7
Therefore the expression is
x=(y-105)/7
Answer: a: 4.1x + 29.
Step-by-step explanation:
Since the perimeter is the length of all 3 sides added up, we do:
2.3x + 14 + -0.2x + 15 + 2x = 4.1x + 29
