Write the equation like this: 275 + 55h = 440. Then, subtract 275 on both sides making the left side cancel out and the right side 165. Lastly, divide 55 on both sides to get h all by itself. The solution is h = 3. You must drive 3 hours longer to reach your destination.
Answer:
Yes
Step-by-step explanation:
y is the litters of water in the tank
x is the time in minutes
m is the change in litters
b is the initial amount of water
so the formula is y = mx + b
whereas m is -14 and b is 770
y = -14x + 770 or y = 770 - 14x
The coefficient of

is
2.
_____
You have used the symbol for "times." If you mean x (the variable), the answer is still the same. The coefficent of

is still
2.
