Answer:
6
Step-by-step explanation:
18×(3/6) = 918×(1/6) = 318×(2/6) = 6
Problem 44
The term "bisect" means "cut in half".
Since BD bisects angle ABC, this means the smaller angles ABD and DBC are congruent.
angle ABD = angle DBC
x+15 = 4x-45
15+45 = 4x-x
60 = 3x
3x = 60
x = 60/3
x = 20
<h3>Answer: x = 20</h3>
========================================================
Problem 45
We use the same idea as the previous problem
angle ABD = angle DBC
2x+35 = 5x-22
35+22 = 5x-2x
57 = 3x
3x = 57
x = 57/3
x = 19
<h3>Answer: x = 19</h3>
So the scale is 3/4 cm for every 6 meters
So if you have 8 cm, we want to find the dimension of the actual wall
convert cm to meters
0.75 cm = 0.0075 meters
8 cm = 0.08 meters
![\frac{0.0075}{6} = \frac{0.08}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B0.0075%7D%7B6%7D%20%3D%20%5Cfrac%7B0.08%7D%7Bx%7D)
Cross Multiply
0.0075x = 0.48
x = 64 meters
P = 21 + 2w
Solve for w
Subtract 21 from both sides.
P - 21 = 2w
Divide both sides by 2.
= w
The first option is correct.
