If R represents Reggie's time, the total time for the team is
.. R +(R +2.45) +(R -3.81) = 3R -1.36
.. = 3*57.12 -1.36
.. = 170.00 . . . seconds
Let
x---------> represents Martin's sister's age
y--------> represents Martin's age
we know that

Part a) An inequality that can be used to represent this situation is
or
Part b) the oldest age Martin's sister can be is years old
Answer:
the number of faces of a cube
Step-by-step explanation:
For an edge length of s, the area of one face of a cube is s^2. The area of all six faces of the cube, the total surface area, is 6s^2. The number 6 represents the number of congruent faces of a cube.
Answer:
Yes-
Step-by-step explanation:
It repeats .121212 infinitely... I assume. You didn't say if it repeated or not.
m_6 + m_8 = 180º because they form a straight line.
So, (2x-5) + (x+5) = 180
3x = 180
x = 60
So, m_115º (2•60 - 5 = 115)
Also, because the two lines are parallel m_6 = m_3 by alternate interior angles.
So, m_3 = 115º
