The number of messages sent by Elsa, Ryan and Jim are 11 , 84 and 21 respectively.
<em><u>Explanation</u></em>
Suppose, the number of messages Jim sent is
As Ryan sent 4 times as many messages as Jim, so the number of messages sent by Ryan
Also, Elsa sent 10 fewer messages than Jim, so the number of messages sent by Elsa
Given that, they sent a <u>total of 116</u> text messages. So the equation will be.......
So, the number of messages sent by each of them.....
Answer: 69,830
Step-by-step explanation: you basically move the decimal to the right for positive left for negitive and move as many places as the power of the exponent
Answer:
= 4n - 2
Step-by-step explanation:
There is a common difference d between consecutive terms in the sequence, that is
6 - 2 = 10 - 6 = 14 - 10 = 18 - 14 = 4
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = 4 , thus
= 2 + 4(n - 1) = 2 + 4n - 4 = 4n - 2
Add 4 to the second equation to get
.. 3b = 6
Substitute this into the first equation to get
.. 2a +6 = 12
.. 2a = 6 . . . . . . . subtract 6
.. a = 3 . . . . . . . . divide by 2
The value of a is 3.
