There are three times as many people at the baseball park today than there were yesterday. Today’s attendance is 15,000. Define

Verizon [17]

The equation is:

3 x = 15,000 where x is the number of yesterday’s attendance

Step-by-step explanation:

There are three times as many people at the baseball park today than

there were yesterday

Assume that the number of the people at the baseball park

yesterday is x

∵ The number of the people at the baseball park yesterday = x

∵ The number of people at the baseball park today is three times

as many as the number of the people yesterday

∴ The number of people at the baseball park today = 3 x ⇒ (1)

∵ Today’s attendance is 15,000

∴ The number of people at the baseball park today = 15,000 ⇒ (2)

- Equate (1) and (2)

∴ 3 x = 15,000

- To find the value of x solve the equation:

3 x = 15,000

The equation is:

3 x = 15,000 where x is the number of yesterday’s attendance

Is 2.5 greater or less than 1,950

OverLord2011 [107]

Answer:

2.5 is less than 1,950.

Step-by-step explanation:

The decimal place is at the end of 1,950.

The decimal place is in the middle of the 2 and the 5.

Since 2.5 decimal place is closer, that means 2.5 has a lower value than 1,950.0.

You can subtract both values.

1,950 - 2.5 = 1,947.50, if it’s greater than 0, it means it has a lower value.

0 < 1,947.50.

Therefore, 2.5 < 1,950
