Answer: Peters age is 25 years old.
The two equations that can be written given the information are:
h = x/5 + 7 and 4h = 2x - 2
When x = Peter's age and h = Phil's age.
If we use substitution, we can come up with the equation:
4(x/5 + 7)= 2x - 2
4x/5 + 28 = 2x - 2
4x + 140 = 10x - 10
150 = 6x
25 = x
Solving this for x, we give us that Peter's age is 25.
Answer:
-3x^2-15x-30
Step-by-step explanation:
Let's simplify step-by-step.
−3(x+3)2−3+3x
Distribute:
=−3x2+−18x+−27+−3+3x
Combine Like Terms:
=−3x2+−18x+−27+−3+3x
=(−3x2)+(−18x+3x)+(−27+−3)
=−3x2+−15x+−30
Solution:
As per the problem
A snail moves 1/40 of a mile in 5/6 of an hour.
We have been asked to find how far, in miles, does it move in one hour?
Since the snail moves 1/40 of a mile in 5/6 of an hour.
So the snail will moves of a mile in hours.
So snail moves miles in 1 hour.
