The two solutions for x are x = 5 or x = 9.

We have some number x in which we subtract off 7. The result of this subtraction (x-7) is the value 2. If the result is negative, we flip it to positive. If the result is positive, we leave it alone. Absolute values are never negative because distance is never negative. Note how x = 5 is 2 units away from 7; similarly, x = 9 is also 2 units away from 7. Here's how you can solve for the two solutions

|x-7| = 2

x-7 = 2 or x-7  = -2

x-7+7 = 2+7 or x-7+7 = -2+7 .... add 7 to both sides

x = 9 or x = 5

x = 5 or x = 9

Therefore you could have scored 5 points or 9 points

Consider the sequence 3, -9, 27, -81, .. Find the 14th term of the sequence.
bagirrra123 [75]

Answer:

let 'a' be the first term, 'd' be the common difference between all the terms of the sequence

Step-by-step explanation:

therefore, a = 3,

and, d = -9 -3

          = -12

hence the 14th term would be,

=> a + 13d

=> 3 + 13( -12 )

=> 3 - 156

=> - 153

A standard deck of playing cards has 52 cards: 13 spades, 13 clubs, 13 hearts, and 13 diamonds. What is the probability of drawi
cestrela7 [59]

13/ 52 = 1/4 chances.

There are 13 spades and 52 cards. You divide the spades and cards in the deck to find your chances of drawing one.

You have a 25% chance of getting a spade.

Now you put it back. Since you put it back, you still have the same number of cards and the same number of spades. So when you divide 13/52 again, the numbers are still the same. 1/4. 25% chance.

So, you still have a 25% chance the second time around.

shutvik [7]
90 books would be left I believe I just took 250/9 since it would take 9 quarters to make $2.50 and since 75% was gone that would mean 25% is left so your answer is 90 unless it’s not but I believe it’s right.
