So, you should add the heighth twice and add the width twice too, then add those two together to get your answer.
Since there are 60 seconds in one minute, we can form the equation:
From here, we can cross multiply.
The train would travel 10,800 feet in one minute.
Answer:
The number is -2
Step-by-step explanation:
Let the number = x
Given that:
Five times the result of adding one to a certain number, is equal to four times the number, plus three.
The equation will be:
5(x+1) = 4x +3
Simplifying
5x + 5 = 4x +3
Taking terms with x on left side and others on right side
5x - 4x = 3 - 5 (sign of transferred terms will be changed)
x = -2
Proof :
Condition 1:
- Add one = -2 +1 = -1
- Multiply 5 = -5
Condition 2:
- 4 times of number = 4 (-2) = -8
- Add 3 = -8 +3 = -5
Hence both conditions have same answer.
I hope it will help you!
Answer:
g(2a) = 4a² - 2
Step-by-step explanation:
substitute x = 2a into g(x) , that is
g(2a) = (2a)² - 2 = 4a² - 2
Answer: Integer
Step-by-step explanation: I would classify -24 as an integer for the best classification. Although -24 is a rational number, we tend to think of negative numbers as integers. Although -24 would be a rational number too, there are many rational numbers in the negatives that have decimals other than 0 so the best classification for it would be an integer.
