A library is having a used book sale. All hardcover books
have the same price and all softcover books have the
same price. You buy 4 hardcover books and 2 softcover
books for $24. Your friend buys 3 hardcover books and
3 softcover books for $21. What is the cost in dollars of a
hardcover book?
Answers
Answer: It should cost $5
Step-by-step explanation:
First you have 4 hardcover and 2 softcover, so 4x+2y= $24 and for your friend it would be 3x+3y= $21.
You have
(3x+3y)2 = 72
(4x+2y)3 = 42
Then subtract them which is 30 you would divide by 6 since 3x2=6
Which gets you to 5.
for the friend the equation would be 3x+3y=$21

Solve for m please. No explanation needed thank you.
Answers
Answer is below.
(Note to asker: Lack of explanations can get my answer deleted)
Step 1
We'll to isolate the variable, but to do that, get rid of the coefficient that multiplies it.
To do that, divide both sides by 22.
[tex]\frac{22m}{22}=\frac{22}{10}[/tex]
Step 2.
Now we have divided both sides by 22, but we'll need to reduce the fraction [tex]\frac{22m}{22}[/tex].
We can reduce the fraction by dividing the factors that are in the numerator and denominator.
That being said, 22 appears both in the numerator and denominator.
[tex]\frac{22m}{22}=m=\frac{2\times5}{2\times11}[/tex]
Step 3
Now, for [tex]\frac{2\times5}{2\times11}[/tex], we'll need to reduce it to the lowest terms. Like in the 2nd step, we'll divide factors that are in the numerator and denominator.
That being said, 2 appears both in the numerator and denominator.
Hence, M = 5/11

guys pls 3 :April and Bill went to the grocery store to buy chocolate bars. April bought 4 small chocolate bars and 6 large chocolate bars, while Bill bought 4 small chocolate bars and 3 large chocolate bars. If April paid $16.50 and Bill paid $11.25, what is the price of a single large chocolate bar?
Answers
Answer:
To do this equation, we could put it in terms of algebra, lets say the large chocolate bars are represented by L and the small bars by S
April
4S + 6L = $16.50
Bill
4S + 3L = $11.25
Looking at this, we can see that the difference between the two purchases is that Bill bought three less large chocolate bars, this means the difference in total cost equals three large chocolate bars. Using this knowledge.
$16.50 minus $11.25 = $5.25
$5.25 = Three Large Bars
Divide this by three to get the cost of one large bar.
$1.75 is the cost of one single large bar.
Step-by-step explanation:

Answer:
Cost of one large chocolate bar = $ 1.75
Step-by-step explanation:
Let the cost of one small chocolate bars = $ s
Let the cost of one large bars = $ l
April:
Cost of 4 small bars = 4*s = 4s
Cost of 6 large bars = 6*l = 6l
Total cost of 4 small bars and 6 large bars = $ 16.50
4s + 6l = 16.50 ------------------(I)
Bill:
Cost of 4 small bars = 4*s = 4s
Cost of 3 large bars = 3*l = 3l
Total cost of 4 small bars and 3 large bars = $ 11.25
4s + 3l = 11.25 ------------------(II)
Subtract II form equation (I)
(I) 4s + 6l = 16.50
(II) 4s + 3l = 11.25 (-)
- - -
3l = 5.25 {Divide both sides by 3}
l = 5.25/3
l = 1.75
Cost of one large chocolate bar = $ 1.75

Answer:
[tex]\frac{c}{6}=2.75[/tex]Step-by-step explanation:
if each person payed $2.75, and there are 6 people, this means we will multiply the two values : the number of people by the amount each person.
This can be demonstrated by saying c = total cost
6 *2.75 = c
this equation says, "a total of 6 people payed 2.75 each, this is what the total cost is (c)"
in other words
c/6 = 2.75
this equation says, "c is the total cost, to find out what each 6 people will pay, in order for the total cost to be payed equally, it will have to be 2.75"

D - The hiker starts at -10 feet then increases their altitude by 10 feet.
Answers
Answer: D
Step-by-step explanation:
Think of it logically: A and C are not below sea level so you can cross them out. And B doesn't work because if you decrease -10 by 10 you get -20. So, D is correct.
