Step-by-step explanation:
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?
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.

Answer:
choice 3) x = 21°
Step-by-step explanation:
5x + 3x + 12° = 180° because they are supplementary angles
combine like terms:
8x = 168°
divide both sides by 8:
x = 21°
Each row contains the degree measures of two complementary angles. Complete the table.
Answer:
10
65
36
90 - x
Step-by-step explanation:
90 - 80 = 10
90 - 25 = 65
90 - 54 = 36
90 - x
The other angles of these complementary pairs are 10°, 65°, 36°, (90-x)°.
What is complementary angle?
Two angles are Complementary when they add up to 90 degrees (a Right Angle). The two angles can be part of the same or different figures.
For the given situation,
The table shows the degree measures of two complementary angles.
We need to find the other angle, which when added sums up 90°.
1. One angle = 80°
Another angle = [tex]90-80[/tex]
⇒ [tex]10[/tex]°
2. One angle = 25°
Another angle = [tex]90-25[/tex]
⇒ [tex]65[/tex]°
3. One angle = 54°
Another angle = [tex]90-54[/tex]
⇒ [tex]36[/tex]°
4. One angle = x°
Another angle = [tex]90-x[/tex]
⇒ [tex](90-x)[/tex]°
Hence we can conclude that the other angles of these complementary pairs are 10°, 65°, 36°, (90-x)°.
