Answer:
X=2.5
Step-by-step explanation:
4+6+4+7+X+(X+1)+8+2/8=5
31+X+(X+1)/8=5
40=31+X+(X+1)
9=X^2+X
X=2.5
16 + (-8) = 8 <== here is one
16 - 8 = 8
8 = 8 (correct)
-12 + 20 = 8 <== and another
11 + (- 3) = 8 <== and another
Answer:

Step-by-step explanation:
we know that
The Pythagorean Theorem states that in a right triangle

where
c is the greater side (the hypotenuse)
a and b are the legs
In this problem
Let
c=AB ---> distance from point A to point B
a ---> the difference of the x-coordinates both points
b ---> the difference of the y-coordinates both points
so

substitute




13 bus seats on each bus and 12 seats on each van
