Answer:
The answer is that each book costs 26 dollars
Step-by-step explanation:
First we subtract 199 dollar from 7 =182
Then we divide 182 dollars to the seven book in order to find a unit =182/7=26
To prove this answer multiply 26 dollars than 7 books and see if the outcome is 182.Then subtract 199 from 182 and see if you got 17.
<span>Angle T = Angle C, let them equal x
So x + x + 140 = 180
2x = 40
x = 20
So Angle T = 20 degrees </span>
Answer:

Step-by-step explanation:
Step 1: Write out equation
d(-3 + x) = kx + 9
Step 2: Distribute
-3d + dx = kx + 9
Step 3: Subtract dx on both sides
-3d = kx - dx + 9
Step 4: Subtract 9 on both sides
-3d - 9 = kx - dx
Step 5: Factor
-3d - 9 = x(k - d)
Step 6: Divide both sides by k - d

Answer:
See below in bold.
Step-by-step explanation:
10.
m < N = 180 - 53 - 44
= 83 degrees.
Using the Law of Sines:
LM / sin 83 = 14 / sin 44
LM = 14 sin 83 / sin 44
LM = 20.
11.
m < ABC = 1/2 * 192 = 96 degrees.
Distribute.
9(times)3 + 8x(times)9
27+72x is an equivalent expression
