1. Jamie purchases gifts for three friends. She chooses a book for $12.80 and then finds two identical necklaces. Her budget is

Evgen [1.6K]

Step-by-step explanation:

1.

(48 - 12.80)/2 = $17.6

2.

250/6 ≈ 42 and more

3.

485 - 319 = 166 more people

4.

14.5x + 80 > 500
14.5x > 420
x > 420/14.5
x > 29

5.

1.25x + 3 ≤ 28
1.25x ≤ 25
x ≤ 25/1.25
x ≤ 20 miles

6. <em>This seems a typo... 460 is likely $60</em>

60x + 145 ≤ 625
60x ≤ 625 - 145
60x ≤ 480
x ≤ 480/60
x ≤ 8 days

What is the solution to the inequality

Dvinal [7]

Answer:

p > 5 and p <-8

Step-by-step explanation:

To solve this, you first need to isolate p.

First add 6 on both sides of the equation:

$-6 + |2p+3| >7\\\\(+6) -6 + |2p+3| >7 +6\\\\2p + 3 > 13$

Then subtract 3 from both sides of the equation.

$2p+3-3>13-3\\\\2p > 10\\$

The divide both sides by 2.

$\dfrac{2p}{2}>\dfrac{10}{2}\\\\p>5$

Another solution is possible because of the absolute value.

If $|2p+3|>13$

Then $|2p+3|$

<em>Thus we can solve the second solution:</em>

$|2p+3|$

$2p+3$

Isolate P again by subtracting both sides by 3

$2p+3-3$

$2p$

Then divide both sides by 2:

$\dfrac{2p}{2}$

$p$

In which number does the digit 4 have a value that is 10 times as great as the value of the digit 4 in 348,971? 284,796 or 327,4

Doss [256]

Answer:

The number is 492,875.

Step-by-step explanation:

Given:

A number that is = $348,971$

Place value of 4 = $40,000$

Place value is ten thousands.

We have to identify the number where the place value of 4 is 10 times of the given number.

Numbers given:

284,796 or 327,498 or 492,875 and 742,186.

Lets see the place value of 4 in each of the number.

⇒

$284,796$ place value of $4$ is $4,000$ .
Place value of 4 is thousands.

⇒

$327,498$ place value of $4$ is $400$ .
Place value of 4 is hundreds.

⇒

$492,875$ place value of $4$ is $4,00,000$ .
Place value of 4 is hundred thousands.

⇒

$742,186$ place value of $4$ is $40,000$ .
Place value of 4 is ten thousands.

Notes:

Ten thousands multiplied with ten is hundreds thousand.

⇒ $10,000\times 10 =1,00,000$

So,

The number which has digit 4 as hundred thousands place values is 492,875.
