Answer:
x = -13
Step-by-step explanation:
9 - 2x = 35
<u>-9 -9 </u>
-2x = 26
divide by -2
x = -13
2 x 18 = 36
5 x 18 = 90
36 + 90 = 126
the coach should order 126 rolls of tape
Answer:
The shortest side is 3”
Step-by-step explanation:
In this question, we can observe that we have 3 sides of a triangle which are not equal in length. These sides are the long, medium and short.
We now have some mathematical statements according to the question.
Since these statements are referencing the short side, let’s start from there.
Let the length of the short side be x. The medium side is 4” more than the short side. This means that the medium side will be the short side plus 4 which mathematically is (x + 4)“. Also, we know that the longest side is 5 times the length of the shortest side. This is mathematically equal to 5x.
Lastly, we are made to know that the perimeter of the triangle is 25”. The perimeter of a triangle can be obtained by adding all the lengths together. This means that:
x + x +4 + 5x = 25
7x + 4 = 25
7x = 25 - 4
7x = 21
x = 21/7
x = 3”

Please let me know if you want me to add an explanation as to why this is the answer/how I got this answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
Answer:
Parallel: a and b, p and q, p and r, q and r
PErpendicular: p&a, p&b, q&a, q&b, r&a, r&b
Step-by-step explanation:
Parallel lines have the same slope so both of the lines would be going in the same direction and will never cross each other.
Perpendicular lines cross at a 90 degree angle.
Technically you do not know if q&a and q&b are perpendicular because you do not know if there is a 90 degree angle
