width of the rectangle = b = x
length of the rectangle = l = 8 + 2x
Perimeter of the rectangle = 70cm
Also, perimeter of the rectangle = 2(l + b)
70 = 2[x + (8 + 2x)]
70 = 2(x + 8 + 2x)
70 = 2(3x + 8)
70 = 6x + 16
70 - 16 = 6x
54 = 6x
54/6 = x
9 = x
Therefore, b = x
b = 9cm
l = 8 + 2x
I = 8 + 2×9
I = 8 + 18
I = 26cm
Sales tax and tip will increase the price of an item.
The cost of each meal is: $10.89
Let the cost of both meals be x.
A 20% tip means that, the current price is:
A 6% sales tax on the meal means that, the current price is:
So, we have:
The amount paid is $27.72
So, the equation becomes
Make x the subject
So, the cost of each meal is:
Hence, the cost of each meal is: $10.89

Answer:
Step-by-step explanation:
The function is all of the ordered pairs (dots/points) on the graph. The definition of a function is that all inputs (x values) have exactly one output (y value). Therefore, this is a function, and the x and y values have been plotted on this graph to more easily visualize the function for you.
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
