(2,3) if you plug in the Y you get 3 on the left side and then you plug in 2 and get 3*2 - 3 which is 6-3 when is 3 as well . So both values on either side are equivalent

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.

<em><u>Explanation</u></em>

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 <u>total of 116</u> 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

you deposit $7,900 in a money-market account that pays an annual interest rate of 4.3%. the interest is compounded quarterly. ho
Sladkaya [172]
<span><span>anonymous </span> 3 years ago</span>we are solving for A, A is the future amount A=? P is the present value, so we were told 7,900, so p=7900 r is the interest rate, so 4.3%, but in decimal form so r=0.043 k is the how often it is 'compounded', it says quarterly, so k=4 n is how long, 3 years, so n=3 <span>A=P(1+<span>rk</span><span>)<span>n∗k</span></span></span> plug in the values

Suppose you are asked to find the area of a rectangle that is 2.1-cmcm wide by 5.6-cmcm long. Your calculator answer would be 11
Jlenok [28]

Answer:

12 square cm correct to 2 significant figures

Step-by-step explanation:

Area of a Rectangle = L X B = 2.1 X 5.6 = 11.76 square cm

To round your result to 2 significant figure, we start counting from the left from the first non-zero digit.

The first two digits are 11 but because the number after is 7 (greater than 4), we round up to 12.

11.76 square cm = 12 square cm correct to 2 significant figures
