Let
x------> <span>speed on the bicycle
y------> </span><span>speed walking
we know that
</span>x=6+y------> equation 1<span>
speed=distance /time-------> time=distance/speed
1/y=2.5/x-------> y=x/2.5------> x=2.5y-------> equation 2
equals 1 and 2
6+y=2.5y-----> 2.5y-y=6------> 1.5y=6-----> y=6/1.5-----> y=4 mi/h
x=6+y-----> x=6+4-----> x=10 mi/h
the answer is
the speed walking is 4 mi/h

Answer:
68 in³
Step-by-step explanation:
Cylinder = 3x2x2x3=36
Sphere = 4/3x3x2x2x2=32
36+32=68
Answer:
C=17.5
Step-by-step explanation:
by simplifying both sides of the equation, then isolating the variable.
The term with degree 4 is

.
The coefficient of the term is the constant number that is being multiplied with the variable of the term. In case of

, the variable is x raised to the power 4 and the constant term that is being multiplied to the variable is 5.
So the coefficient of of term of degree 4 is 5.
Thus correct answer is option D
