L = longer piece s = shorter piece
{ l + s = 63
{ l = s + 15
l + s = 63
(s + 15) + s = 63
2s = 63 - 15
2s = 48
s = 48
2
s = 24
l + s = 63
l + 24 = 63
l = 63 - 24
l = 39

Answer:The value of the expression increases as r decreases.
Step-by-step explanation:
To find : What happens to the value of the expression as r decreases?
Given Expression: 80-2r
We check for different value of r as decreasing order,
r 80-2r
5 80-10=70
4 80-8=72
3 80-6=74
2 80-4=76
1 80-2=78
As r decreases the value of expression increases.
Therefore, the value of the expression increases as r decreases.
Hope this helps!
Answer:
(B)
Step-by-step explanation:
We have to construct two equilateral triangles that is one with the side length of 2 inches and the another triangle with side length of 3 inches.
Now, both the triangles are equilateral triangles, thus they have same shape.
Also, both triangles have different side lengths, one having 2 inches and another having 3 inches, thus they have different size.
Hence, the true statement about the two triangles is:
The two triangles are the same shape but not the same size.
Therefore, option B is correct.
A mixed number is one that has an integer along with a proper fraction, so that would be (for this improper fraction):
50/12 = 4 1/6
12 goes into 50, 4 times with a remainder of 2
you get: 4 and 2/12, but 2/12 can be reduced further to 1/6
so that's how i got the answer of 4 1/6
4·5=20 2·10=20 3·5=15 6·2=12 15+12=27 It's 27/10
