The numbers are 3 and 7
Step-by-step explanation:
Let the first number be x and the second number be y
Then according to given statement
One number added to three times another number is 24
x+3y=24 Eqn 1
Five times the first number added to three times to other number is 36
5x+3y=36 Eqn 2
Subtracting Equation 1 from equation 2
Dividing both sides by 4
Putting x=3 in equation 1
Dividing both sides by 3
Hence,
The numbers are 3 and 7

Answer:
The expression is ⇒ 2nd answer
Step-by-step explanation:
* Lets explain how to solve the problem
- In the exponent rules, we add the exponents when we multiply terms
have same base
- Ex:
- The volume of the rectangular box is the product of its three
dimensions
* Lets solve the problem
- John buys a water tank from a company
- The tank he buys has the dimensions b² by b^4 by 4c³
∵ The water tank is shaped a rectangular box
∵ The tank has dimensions
∵ The volume of the tank = L × W × H , where L , W , H are the
dimensions of the tank
- Assume that L = b² , W = and H = 4c³
∴ The volume of the tank = b² × × 4c³
- b² and b^4 has the same base, then add its exponents
∴ The volume of the tank = × 4c³
∴ The volume of the tank = × 4c³
∴ The volume of the tank =
* The expression which represents the volume of the tank is:
∴ The answer is the second expression
