Răspuns:
150 m
Explicație pas cu pas:
Reamintim:
Perimetrul unui dreptunghi, P
P = 2 (lungime + lățime)
P = 400
Lățime = x
Lungime = 3x
Astfel, avem:
400 = 2 (3x + x)
400 = 2 (4x)
400 = 8x
Împărțiți ambele părți la 8
50 = x
Lungime = 3x
Lungime = 3 * 50
Lungime = 150 m
Answer:
or 
(Not sure which one is preferred in your case)
Step-by-step explanation:
<u>Key skills needed: Evaluating expressions</u>
1) We are given: 
2) To solve for the x variable, we want to leave the term with "x" by itself.
This means we add 10 to both sides
--> 
(Since -10 and +10 cancel out to make 0 or nothing)
3) Then we divide by 5 on both sides to get "x" completely by itself.
-----> 
4) You can keep it as is so --> 
or you can divide "y" by 5 and "10" by 5 and get --> 
(I am not sure which form is preferred one is preferred as the teacher matters)
<em>Hope you understood and have a nice day!!</em>
I believe the answer will always be one.
Heres an example: 5/8 • 8/5 = 1
<span>17x=18(1/3)
17x = 6
x = 6/17

Answer:
Avoid Using too many statistics
Step-by-step explanation:
when a speaker is giving a speech, the listeners prefer main points to hearing too much of statistics. Too many statistics bore the audience and sometimes divert their attentions from the crux of the speech. If statistics are to be given, they must be clearly expressed and the source should be clearly stated.
Numbers that are of large decimal points can be rounded off so as not to confuse the audience and to make them grasp the main idea.
