1. La suma de dos números es 115. El número mayor es dos veces más 22 unidades que el otro. Hallar

Lerok [7]

De acuerdo con un sistema de ecuaciones, tiene-se que los números son 31 y 84.

----------------

En el sistema de ecuaciones, tiene-se que los números son x e y.
Suma de 115, o sea, $x + y = 115$
<u>El número mayor es dos veces más 22 unidades que el otro</u>, o sea, $x = 2y + 22$

----------------

Primero se encuenta el número menor, <u>reemplazando la segunda ecuación en la primera:</u>

$x + y = 115$

$2y + 22 + y = 115$

$3y = 93$

$y = \frac{93}{3}$

$y = 31$

----------------

El número mayor es dado en <u>función de el menor</u>, o sea:

$x = 2y + 22 = 2(31) + 22 = 62 + 22 = 84$

Los números son 31 y 84.

Can someone explain me this please

AfilCa [17]

$\purple{\maltese}\large\underline{\underline{\red{\sf\:\: Given :}}} \\$

Mass (M) of space shuttle = 1.0 × 105 kg.
Altitude (r) = 200.0 km

$\\\purple{\maltese}\large\underline{\underline{\red{\sf\:\: To \: \: Find :}}} \\$

The force of gravity that the space shuttle experiences = ?

$\\\purple{\maltese}\large\underline{\underline{\red{\sf\:\: Solution :}}} \\ \\$

$\purple{\maltese}\large\underline{\underline{\sf\:\: using \: formula :}} \\ \\$

$\bigstar \: \underline{ \boxed{\sf { \pink{g = \frac{G \: M}{{r }^{2} }}}}} \\ \\$

$\\ ❒\: \: \underline{\textbf {Putting values \: in \: the \: \: given \: formula :}} \\$

$\sf \implies \: g = \frac{G \: M}{{r }^{2} } \\$

$\sf \implies \: g = \frac{6.67×10^{-11} × 1.0×10^5}{(2×10^5)^{2} } \\$

$\sf \implies \: g = \frac{6.67×10^{-6}}{4×10^{10}}\\$

$\sf \implies \: g = \frac{6.67×10^{-6}}{4×10^{10}} \\$

$\sf \implies \: g =1.6675×10^{-6-10}\\$

$\sf \implies \: g =1.6675×10^{-16}\: Newton\\\\$

$\:\:\:\:\:\:\:\qquad\rule{150pt}{2pt} \\\\$

Henceforth, the force of gravity experienced by the shuttle is <u>1.6675×10^N</u>

Hello , can someone one paraphrase this i want it same but how to paraphrase it what should i write

Misha Larkins [42]

Answer:

$\text{Well, one way you can write these types of things, is by replacing the "so it " portion}\\\text{This can be accomplished by using three little dots in the shape of a triangle:}\\\text{The therefore symbol: }\therefore\\\text{So, for example: }p>n, \therefore \text{is p-type}$

What is 1,345 /99 rounded to the nearest integer?

mylen [45]

It's 14 because when you divide you get 13 with a remainder of 58 which is over half of 99 which means that you round up to 14
