let the first number be x
let the second number be y

x+y=203203------eqn1
x-y=3131----------eqn2
subtract eqn2 from eqn1. you'll have
2y=200072
y=100036
substitute y=100036 in eqn1, you'll have
x+(100036)=203203
x=203203-100036
x=103167
∴ x(the first number)=103167
   y(the second number)=100036

Answer:

150m^2

Step-by-step explanation:

Each square on a cube is 5 by 5 meters long.

The area of each square is 5 * 5, which is 25 square meters.

There are 6 sides on a square, so multiply 25 by 6, and you will get 150.

Anita can clean a typical pool in 8 hours. Chao can clean a typical pool in 6 hours. How long should it take Anita and Chao work
Snezhnost [94]
This kind of problems requires to add the working velocities. The total velocity is the sum of the individual velocities.

Anita's velocity = 1 pool/8 hours
Chao's velocity = 1 pool/6 hours

Combined velocity 1/8 + 1/6 = (3 + 4)/24 = 7/24 pool/hour

Time = 1 pool / (7/24) pool/hour = 24/7 hour =3.43 hours

Answer:

We conclude that:

''add 3 and the sum of 9 and v'' is algebraically represented by the expression as:

  • 3 + 9 + v

Step-by-step explanation:

Given the statement

''add 3 and the sum of 9 and v''

Let us break down the statement

  • Let the number be:  v
  • The sum of 9 and v: 9+v

so

Adding 3 and the sum of 9 and v will be: 3 + 9 + v

Therefore, we conclude that:

''add 3 and the sum of 9 and v'' is algebraically represented by the expression as:

  • 3 + 9 + v
