Answer:
-6 is the same as Subtracting 6, C.
Hope this helps!
Step-by-step explanation:
For example,
5 - 6
5 is positive, +5
and 6 is negative, -6
27 because 6*9 is 54,54 divided by 2 is 26
The distance travelled by east bound car is 60 km.
<u>Explanation:</u>
Distance travelled by North bound plane = 63 km
Distance travelled by east bound plane = 87 km
Distance travelled by east bound plane = ?
The trajectory of the plane would form a triangle.
In a right angle triangle:
(hypotenuse)² = (base)² + (height)²
(87)² = (b)² + (63)²
7569 = b² + 3969
b² = 3600
b = 60 km
Therefore, distance travelled by east bound car is 60 km.
