Note: <em>It seems you mean a piece of string is 3.5 long. So, I am assuming that a piece of string is 3.5 cm long.</em>
Answer:
140 cm of the original piece is left after Joe cuts three pieces.
Step-by-step explanation:
Given the piece of string
As we know that
so the length of a piece of string = 350 cm
As joe cuts three pieces from it, and each 70 cm long.
so the total length of three pieces which were
cut by joe = 70cm + 70cm + 70cm = 210 cm
So, subtracting the total length of the three pieces that were cut from the total length of the string:
350 cm - 210 cm = 140 cm
Therefore, 140 cm of the original piece is left after Joe cuts three pieces from it.
2(b-5)+7b-4
Solve 2(b-5) to get 2b-10
Combine your like terms 2b-10+7b-4
Solve 2b+7b to get 9b
Solve -10+(-4) to get -14
So your answer is
9b-14
Answer:
La cantidad de dinero
Celia tiene = x = 9.33 €
Quique tiene = y = 4.67 €
Step-by-step explanation:
Representemos la cantidad de dinero
Celia tiene = x
Quique tiene = y
Entre Celia y Quique suman 14 €.
x + y = 14
x = 14 - y
Si Celia tuviera 1 euro, tendría el doble de dinero que Quique.
Por lo tanto,
x = 2 años
Nosotros sustituimos
2y + y = 14
3 años = 14
y = 14/3
y = 4.67 €
x = 14 € - y
x = 14 € - 4.67 €
x = 9.33 €
Por lo tanto,
La cantidad de dinero
Celia tiene = x = 9.33 €
Quique tiene = y = 4.67 €
The surface area would be 980.17 (980.17690792002 not rounded)
