Simplified: 3x+7y+(-2y)+9
Coefficient of y: 5
Constant: 3 and 6
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:
There are 1,892,800,000 different standard plates that are possible in this system
Step-by-step explanation:
The plates follow the following format:
D - D - L - L - L - D - D - D
For each digit there are 10 possible outcomes, and for each letter there are 26 possible outcomes.
So, there are
10*10*26*26*28*10*10*10 = 1,892,800,000
different standard plates that are possible in this system
