Sharla is 8 year older than her sister, patricia . The sum of their ages is 102.Find their ages.​
Alisiya [41]

Answer:

Patricia is 47 years old

Sharla is 55 years old

Step-by-step explanation:

Rewrite the first sentence as an equation: (S= Sharla) (P= Patricia)

S=P+8

Rewrite the second sentence as an equation:

S+P=102

1) Substitute P+8 as Sharla in the second equation:

P+8+P=102

2) Combine alike terms:

2P+8=102

3) Subtract 8 from both sides:

2P=94

4) Divide both sides by 2:

P=47

5) Substitute 47 as P in the <u>First</u> equation:

S=47+8

6) Solve:

S=55

Tenía 5.00 $ que mi mamá me dio 10.00 $, mientras que mi papá me dio 30.00 $ y mi tía y mi tío me dieron 100.00 $ y yo tenía otr
olga2289 [7]

Responder:

<h2>$ 150 </h2>

Explicación paso a paso:

Si inicialmente tengo $ 5 y mi madre me dio $ 10, el dinero total inicial que tengo será $ 5 + $ 10 = $ 15

Si mi papá me dio $ 30, mi tía y mi tío me dan $ 100, el monto recibido de mi tía y mi tío será de $ 30 + $ 100, es decir, $ 130

Como tengo otros $ 5 para todo este dinero, el dinero que realmente tengo será la suma total de todo el dinero recibido más mi dinero personal.

Dinero que realmente tengo = $ 15 + $ 130 + $ 5

= $ 150
