Turn 8/200
into a decimal using an equivalent fraction show your steps

Answers

Answer 1

Answer: First I'd reduce it to 4/100 because every fraction is easier to make a decimal over 100. Now write the four and for every extra 0 add a 0 between the decimal and the number. the answer is 0.04 but also remember when using this trick. If the number over 100 has a decimal you have to keep those ones too

Answer 2

Answer: 8/200
= (8/2) / (200/2)
= 4/100 (equivalent fraction)
= 0.04

The final answer is 0.04~

Is -2 + 4y +2=8x a direct variation equation

Answers

Direct variation

Explanation:

Given –2 + 4y + 2 = 8x.

To find the given expression –2 + 4y + 2 = 8x is direct variation or not.

If y varies directly as x, then y = kx.

If y varies inversely as x, then $y=(k)/(x)$

⇒ –2 + 4y + 2 = 8x

Combine like terms together.

⇒ –2 + 2 + 4y = 8x

⇒ 4y = 8x

Divide both sides of the equation by 4, we get

⇒ y = 2x

Which is in the format of y = kx.

Thus y varies directly as x.

Hence, –2 + 4y + 2 = 8x is direct variation.

Lana and Emily are playing a competitive word game. Whoever plays all of their tiles first gets to add the value of their word plus the total value of all of their opponent’s remaining tiles to their score. Also, the opponent must subtract the total value of all of their tiles from their score.Suppose that the current score is: Lana 324, Emily 358. If Lana’s last word is worth 7 points, how many points does she need Emily to have in her hand in order to win?

Suppose that the current score is: Lana 324, Emily 358. If Lana’s last word is worth 7 points, how many points does she need Emily to have in her hand in order to win? ___________ points

Hint: If Emily had 5 points in her hand, by how much would the difference between the player’s scores change?

Answers

Lana gets the 7 points so she ends up with 331. She will then be 358-331=27points behind Emily. She needs to win, so there needs to be 1 more than 27 points of change in the score, or 28 points. Emily's hand value is added to Lana's and also subtracted from Emily's so her hand is worth twice the value as the amount. (If the hand is worth 10 points, it changes the scores by 20 points). Thus, we only need half of the 28 points of change for Lana to win. The answer is 14 points.
