a. you would do 1346/1500 to get 0.8973333333333. i you want to check that you can do 1346/0.8973333333333 and you would get 1500. I'm just going to round 0.8973333333333 down to 0.897. So for town B you would also do 1546/1800 which brings you to 0.858889 you can again do 1546/0.858889 but i found that 0.8588888888 gives you the most accurate answer. so rounding that down to 0.859
b. you can see that 0.897 is a larger percent that 0.859 so town a had a larger increase than b
For identifying the slope of a line, is easier if we get the equation to its slope-intercept form, that is:
y = mx + b
where m is the slope, and b is the y axis intercept. So we'll change the original equations and get them to this form:
<span>3y+ x= 12
3y = -x + 12
y = (-1/3) + 4
therefore the slope is -1/3 and the y-axis intercept is 4
-9x + 4y = 16
4y = 9x + 16
y = (9/4)x + 4
therefore the slope is 9/4 and the y-axis intercept is 4</span>
Very easy:
put the 10 and 12 end to end then back off the 7 inches
22-7 = 15
The first number is 3 and the second number is 5.
