Answer:
It depends on how much you drive If you don't drive a lot option B would be the cheapest but if you do drive a lot option A would be the cheaper option.
Answer:
<h2>x = -7 and y=8</h2>
Step-by-step explanation:
<h2> soln</h2><h2>using by elimination method</h2><h2> 1|x+2y=9</h2><h2> 1| x+y=1</h2><h2> |x+2y=9</h2><h2> -|x+y=1</h2><h2> x-x+2y-y=9-1</h2><h2> 0+y=8</h2><h2> y=8</h2>
<h2> 1|x+2y=9</h2><h2> 2|x+y=1</h2>
<h2> |x+2y=9</h2><h2> -|2x+2y=2</h2>
<h2>x-2x+2y+2y=9-2</h2>
<h2>-x=7</h2><h2>divide -1 both side with the make value of x</h2><h2>x=-7</h2><h2>therefore x=-7 and y=8. this is my answer</h2>

Answer:
6160
Step-by-step explanation:
If you do not understand my solution, send a picture of how your teacher does it and I will guide you in the same style as your teacher.
you have numbers: 16 28 40 77. I will write each number in each line and show its multiple numbers: Now that if you multiply the numbers I write, you get the same number. For example, 2*2*2*2 = 16 (same for the rest)
16: 2 2 2 2
28: 2 2 7
40: 2 2 2 5
77: 7 11
From the above, we pick 2*2*2*2*5*7*11 = 6160
I got that by picking a number comprised of factors that appear in at least any of the numbers 16 28 40 77
The simplest I can put it
10^1 = 10
10^2 = 100
10^3 = 1000
(essentially the number of zeroes)
5*10^2 = 5*100 = 500 (adding 2 zeroes, or moving the decimal over 2 places
Same works for numbers smaller than zero
5*10^-2 = 5*.01 = .05 (moving the decimal to the right 2 places
