Round to the nearest ten thousand 276,431

1 answer:

4 0

Ten thousand is 10 000, which means that our number will have 4 zeros at the end.

so is i

270 000
?

well, the question is: is the number that the first 0 replaced 5 or higher? yes, yes it is, it is "6"

so we have to make the first not-replaced number bigger by 1:

the correct answer is 280 000

Damon is saving for a vacation. He estimates that he'll need about $2,500 for the trip. He created an equation last week to mode

Anika [276]

Answer:

<h3>He needs 5 more months of savings for him to reach his goal. </h3>

Explanation:

Given the equation that models Damon's saving plan as y = 500 + 400x where x represents the number of months since last week and y represents the total amount he's saved for the vacation. Since he estimates that he'll need about $2,500 for the trip, therefore y = $2,500.

In order to determine how many more months of saving (x) it will take to reach his goal, the following steps must be taken by Damon (Damon true statements)

Step 1:

y = 500 + 400x

Step 2: Subtract 500 from both sides

y - 500 = 500 + 400x - 500

y-500 = 400x

Step 3: Substitute y = $2500 into the resulting equation and solve for x

400x = 2500-500

Step 4: Take the difference of the value at the right hand side of the equation

400x = 2000

Step 5: Divide both sides by the coefficient of x (i.e 400)

$\frac{400x}{400}= \frac{2000}{400}$
