It would be 91.91 because it is closer to 100, or any other greater number than 81.9 is. You could also look at it as, when you count, the number that you say first, is the smallest. So in this case, you'll say 81 before you say 91.
Hope you understand it in the way that I meant it. (:
Answer:
Step-by-step explanation:
Translating the phrase into an equation, we get:
And:
So the system of equations would be:
If you want to put it into slope-intercept form, you can simplify both equations:
Answer:
16x+16
Explanation:
The perimeter is all of the sides added up. On a rectangle, only 2 sides are needed to know the perimeter because measurements are equal on both sides.
1) Write equation
2*5 + 2(8x+3)
2) Distributive property and multiply
10 + 16x + 6
3) Combine like terms
16x+16
Answer:
w= 6
Step-by-step explanation:
I just started by making an educated guess using the values already given. Then I inserted that into the problem to see if it worked.
L= 2w - 5
I used 6 as a random, educated guess for the value of w.
L = 2(6) - 5
L = 12-5
L = 7
Then, multiply L by 2 to account for both side lengths of the rectangle.
7(2)= 14
Subtract that value from the total perimeter to find what the width must equal.
26 - 14 = 12
Divide that answer by 2 since there are two sides for width.
12/2 = 6
I know this was kind of long, but I hope it helps! :)
