Cross multiply first. You would get 6x=4, and divide both sides by 6, which would get you 4/6 which simplifies into 2/3.

elsa,ryan, and jim sent a total of 116 text messgaes during the weekend. ryan sent 4 times as many messages as jim. elsa sent 10

kozerog [31]

The number of messages sent by Elsa, Ryan and Jim are 11 , 84 and 21 respectively.

Explanation

Suppose, the number of messages Jim sent is $x$

As Ryan sent 4 times as many messages as Jim, so the number of messages sent by Ryan $= 4x$

Also, Elsa sent 10 fewer messages than Jim, so the number of messages sent by Elsa $= x-10$

Given that, they sent a total of 116 text messages. So the equation will be.......

$x+4x+(x-10)=116\\ \\ 6x-10=116\\ \\ 6x= 126\\ \\ x= \frac{126}{6}= 21$

So, the number of messages sent by each of them.....

$Jim = 21\\ Ryan = 4*21= 84\\ Elsa= 21-10= 11$

The number of coffee shops in a certain country can be modeled by the quadratic function f(x)105x²+680x+4296, where f(x) is th

grigory [225]

A. X is the number of years after 2000

2006-200 = 6 years.

Replace x with 6 and solve:

105(6)^2 + 680(6) + 4296 = 12,156

Answer for part a: 12,156

Answer for part B.
There was just over 12,000 in 6 years , to get to 21,500 would be a little over 9,000 more 9/12 = 0.75

6 years x .75 = 4.5 years

6 + 4.5 = 10.5 years round to 10 years for estimating purposes

Answer for part b: about 10 years
