nadezda [96]

Answer:

I think she should get the Verizon house hold Wifi because when you compare the prices even if Monica doesn't want any extra channels she would still save $15. Even tho the extra channel was $4 for the Comcast when you add it up you get $64 instead when you use Verizon even tho you pay $6 for extra channels you still don't get the amount for the Comcast which you save $13 by getting Verizon with $51.

Richard and Teo have a combined age of 20. Richard is 2 years older than twice Teo’s age. How old are Richard and Teo?

boyakko [2]

Richard is 14 years old and Teo is 6 years old.

Step-by-step explanation:

Let,

Richard's age = x

Teo's age = y

Combined age = 20 years

According to given statement;

x+y=20 Eqn 1

x = 2y+2 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$(2y+2)+y=20\\2y+2+y=20\\3y=20-2\\3y=18$

Dividing both sides by 3

$\frac{3y}{3}=\frac{18}{3}\\y=6$

Putting y=6 in Eqn 2

$x=2(6)+2\\x=12+2\\x=14$

Richard is 14 years old and Teo is 6 years old.
