Answer:
-4+8+-16+32+-64+128 = 84
Step-by-step explanation:
The fifth and sixth terms are -64 and 128
Since, the fundraiser only have three prices for books($2, $5 and $10), the number of $5 book that was sold is 12.
<h3>How to form equation and solve ?</h3>
The fundraiser only have 3 prices for books which are $2, $5 and $10.
There were 6 more $5 books sold than $10 books sold.
Let
x = number of $10 book sold
Therefore,
number of $5 books sold = x + 6
There are 8 more $2 book sold than $10 book sold. Therefore,
number of $2 books sold = x + 8
A total of $250 was raised.
Therefore, the total amount sold forms the following equation:
10x + 5(x + 6) + 2(x + 8) = 250
10x + 5x + 30 + 2x + 16 = 250
17x = 250 - 30 - 16
17x = 204
x = 204 / 17
x = 12

Solving problems means making choices. Typically, effective problem-solving skills result in “happier, more confident, and more independent” individuals. When children tackle problems on their own, or in a group, they become resilient
Answer:
16
Step-by-step explanation:
Median means the middle number. So you can look at it like this:
<em>a,b,</em> 20, <em>c,d</em>
Those are the variables for the numbers we do not know. We do know that they are all even numbers and they are consecutive, meaning in sequence. So if they are all even, then there should be a gap of 2 between each. They should also be in order. Knowing that, you can subtract 2 from 20 to get b, subtract 2 from b to get a, add 2 to 20 to get c, and add 2 to c to get d.
This should be your answer:
16, 18, 20, 22, 24
Consecutive, and even.
