Answer:
The eastbound train travels at 92 mph and the westbound train travels at 96 mph.
Step-by-step explanation:
We know that Velocity = distance / time
If the eastbound train travels at x miles per hour, the westbound train travels at x + 4 mph.
After 3.5 hours, they are 658 miles apart. If we solve for distance the formula given above we have: Distance = velocity x time. We have that the total distance between both trains is 658 miles.
Substituting the values of the problem and solving for x we have

Thus, the eastbound train travels at 92 mph and the westbound train travels at 96 mph.
Answer:
I am on this same question and have no idea
Step-by-step explanation:
59
Step-by-step explanation:
7 × 5 = 35
6 × 4 = 24
35 + 24 = 59
because 4 + 5 is 9 and 3 + 2 is 5
so 59
X = - 4; y = 3; z = 2;
2 x² - 2 z^4 + y² - x² + z^4 =
= 2 * (-4)² - 2 * 2^4 + 3² - ( -4)² + 2^4 =
= 2 * 16 - 2 * 16 + 9 - 16 + 16 =
= 32 - 32 + 9 - 16 + 16 = 9
Answer:
Option C
Step-by-step explanation:
Since, Y and Z are the midpoints of sides AB and CD of the given trapezoid.
Segment YZ will the midsegment of trapezoid ABCD.
By the theorem of midsegment,
m(YZ) = 
By using expression for the length of a segment between two points,
Length of a segment = 
Distance between two points A(-5, -6) and D(3, 2),
AD = 
AD = 
AD = 
AD = 
Distance between B(-6, -2) and C(-4, 0)
BC = 
BC = 
BC = 
Therefore, m(YZ) = 
= 
= 
Option C will be the answer.
