Answer:
Step-by-step explanation:
-Solve for the value of :
-Take and add it to :
-Subtract both sides by :
So, the value of is .
Mark drove for 5 hrs
pranav drove for 3 hrs
Distance = speed x time
Pranav =50kmh x 3hrs
= 150 km
* note that they drove the same distance
Speed of mark=distance / time
=150 km / 5hrs
= 30 kmh
subtract 6.4 from 25 = 1.3c + 18.6
Answer:
☆ y=kx
Example: if we have x= 3 and y= 15
Find y?
y= kx
*We know that y= 15 and x= 3
So,
15=k(3)
15=3k
*divide 3 from both sides
K=5
y=5x
y=5(5)=25
