4. 2n= -8
5. n = -8/2
6. n = -4
Answer:
-12
Step-by-step explanation:
So to start we need to know what makes a line parallel. In an equation we know that for lines to be parallel they must have the same slope(m).
Then, we need to know the slope-intercept form of an equation. The slope intercept form is 
where 
is the slope of the line and 
is the y-intercept. In this problem where can see the second equation is already in this form.
Now that we know we need to find the slope, and we know that the second equation is in slope-intercept form we're going to convert the fist equation into the correct form.
To do this, we know we need to make sure 
is the only thing on the left side of the equal sign. Currently, on the left side of the equal sign we have 
so we have to divide both sides by 
to get 
Now that we have it converted to slope-intercept form, we are going to look for what represents the slope or in the equation. In this case the slope would be -12, so any line with a slope of -12 will be parallel.
Answer:
25
Step-by-step explanation:
Given:
32 parks allow camping
43 parks allow playgrounds
10 parks both allow camping and playgrounds
110 total parks
First, we need to add 32, 43, and 10
32 + 43 + 10 = 85
Then, we find the difference of 110 and 85
110 - 85 = 25
Since it isn't a decimal, there is no point in rounding.
If a number has a decimal that is .5+, you round up. If it is .4-, you round down. So 817.502 would be 818.
The perimeter is 86 m.
When you add the 18 with the 11, you get the length of the bottom side, which is 29. When you add the nine and the 6, you get the length of the left side, which is 15. Now add everything together.
18 + 6 + 11 + 9 + 29 + 15 = 86 m
Hope I helped. Good luck!! : )
