Last week Mark ran 31 miles more than Jack. Mark ran 46 miles .How many miles did Jack run
Levart [38]
You take what Mark ran, 46 miles, and you see that Mark ran 31 more miles than Jack, so the equation would be 46-31, which would be 15 miles. So, Jack ran 15 miles.

Carla and Jonah are working together to determine if quadrilateral CDEF with coordinates C(2, 3), D(1, 2), E(4, 1), and F(5, 3)
alukav5142 [94]

Answer:

Option (B)

Step-by-step explanation:

CDEF is a quadrilateral having vertex C(2, 3), D(1, 2), E(4, 1), F(5, 3).

To prove that the given quadrilateral has a right angle, we will use the property of perpendicular lines.

m_1\times m_2=-1

where m_1 and m_2 are the slopes of the consecutive sides of the quadrilateral.

Since CD and DE are the consecutive sides of the quadrilateral, Carla is on the right track by finding the slopes of CD and DE.

Since Jonah is finding the slopes of opposite sides so he will not be able to use the property of perpendicular lines.

Option (B) will be the answer.
