The sales tax is 2$ Hope this is the answer you're looking for.
6,2,8,4,and 0 are the only possible value of the ones digit, because
6*1=6, last digit is 6
6*2=12, last digit is 2
6*3=18, last digit is 8
6*4=24, last digit is 4
6*5=30, last digit is 0
6*6=36, last digit is 6
and the whole cycle goes over again.
Answer:
45 cm
Step-by-step explanation:
2 lines will divide the square in thirds. 2 additional lines will divide those thirds into ninths. Pat's 4 lines total 18 cm.
To divide the square into sixths requires 5 lines. To divide it into 36ths requires 5 additional lines. Hence the total number of lines on the second paper is 10/4 = 5/2 times the total on the first paper.
The total length of lines on the second paper is ...
(5/2)(18 cm) = 45 cm
Answer: $12
Step-by-step explanation:
For this problem, we can use system of equations to solve. Let's use x for shirts and y for ties.
Equation 1
6x+3y=79.5
This equation comes from the first sentence. 79.5 is the total cost.
Equation 2
3x+2y=41
This equation comes from the second part of the first sentence. 41 is the total cost.
Since we are looking for the cost of each shirt, let's use the elimination method to eliminate y. First, we need to multiply both equations to that the y in both equations equal each other.
2(6x+3y=79.5)
3(3x+2y=41)
Now that we have chosen a common number, we can multiply.
12x+6y=159
9x+6y=123
We can now subtract both equations to cancel out y.
3x=36
Divide to get x alone.
x=12
Each shirt costs $12.
