Answer:
d = 11
Step-by-step explanation:
Isolate the variable (d). Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 5 to both sides
2d - 5 (+5) = 17 (+5)
2d = 17 + 5
2d = 22
Next, divide 2 from both sides
(2d)/2 = (22)/2
d = 22/2
d = 11
11 is your answer for d.

x=-3
This is because when a line is vertical, then it has an undefined slope and so it must have a value for x only. This shows it must be x=-3.
Answer:
The building is 16 m tall.
Step-by-step explanation:
x/2 = 80/10
10x=160
10x/10 = 160/10
x=16
I believe you have to add both numbers and subtract it by 180.
Example on number 1.
45+55=89
180-89=91
