Step-by-step explanat
5-4=1 keep the 17 the same so its 1/17
There u good :)
Answer:
36.8 or 37 yards of fabric
Step-by-step explanation:
23 yards of fabric = five dresses
23 divided by five equals four point six
four point six multiplied by eight dress equals 36.8
23 yds of fabric = 5 dresses
23÷5=4.6
If you need to know how many yards of fabric, then you'd do:
4.6×8
4.6 is the amount of each yards 5 dresses are in and so if you times that by how many dresses you need now, you'll get:
36.8 yards of fabric
To round, it'd be 37 yards of fabric
15 and 1/8, 15 and 3/8, 15 and 5/8
= 15.125, 15.375, 15.625
Resposta:
Primer rectangle:
Amplada = 11
Longitud = 14
Segon rectangle:
Amplada = 12
Longitud = 15
Tercer rectangle:
Amplada = 13
Longitud = 16
Explicació pas a pas:
Donat que:
Primer rectangle:
Amplada = x
Longitud = x + 3
2n rectangle:
Augment de la dimensió d'1 cm respecte al primer rectangle;
Amplada = x + 1
Longitud = x + 4
3r rectangle:
Augment de la dimensió de 2 cm respecte al primer rectangle;
Amplada = x + 2
Longitud = x + 5
Suma dels tres perímetres del rectangle:
Perímetre d'un rectangle: 2 (l + O)
Primer rectangle:
2 (x + x + 3) = 2 (2x + 3) = 4x + 6
2n:
2 (x + 1 + x + 4) = 2 (2x + 5) = 4x + 10
3r:
2 (x + 2 + x + 5) = 2 (2x + 7) = 4x + 14
Suma de perímetres = 162
(4x + 6 + 4x + 10 + 4x + 14) = 162
12x + 30 = 162
12x = 162 - 30
12x = 130
x = 11
Per tant,
Primer rectangle:
Amplada = 11
Longitud = 11 + 3 = 14
2n rectangle:
Amplada = 11 + 1 = 12
Longitud = 11 + 4 = 15
3r rectangle:
Amplada = 11 + 2 = 13
Longitud = 11 + 5 = 16
:) Hope this helps you to your question
