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

Answer:

f(-3) = g(-3)

Step-by-step explanation:

Let's look at each option to which one is true with regard to the given functions on the graph.

The option that is correct is the option that shows where the graph of f(x) and g(x) intercepts or cut across each other.

Now, take a look at the graph, the line of both functions intercepts at x = -3. At this point, the value of f(-3) and g(-3) is equal to -4.

Therefore: f(-3) = g(-3)

Directions: Find each value or measure. Assume that segments that appear to be tangent are tangent ​
SOVA2 [1]

Answer:

x = 7, x = 5

Step-by-step explanation:

Given 2 intersecting chords, then

The product of the parts of one chord is equal to the product of the parts of the other chord.

(1)

27x = 9 × 21 = 189 ( divide both sides by 27 )

x = 7

(2)

12(3x - 5) = 120 ( divide both sides by 12 )

3x - 5 = 10 ( add 5 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5
