Kimora’s cell phone company charges her $35 a month for phone service plus $.05 for each text message sent. How many text messag

professor190 [17]

Given that Kimora’s cell phone company charges her $35 a month for phone service plus $.05 for each text message sent.

Kimora's cell phone bill for one month is $52.

We need to determine the number of text messages Kimora sent for one month.

Also, we need to write and equation and solve it.

The equation:

Let x denote the number of text messages Kimora sent for one month.

Thus, the equation is given by

$35+0.05x=52$

Therefore, the equation for the number of text messages Kimora sent for one month is $35+0.05x=52$

Solving the equation:

We need to solve the equation $35+0.05x=52$

Subtracting both sides of the equation by 35, we get;

$0.05x=17$

Dividing both sides of the equation by 0.05, we get;

$x=340$

Therefore, the number of messages sent is 340.

Consider parallelogram VWXY below.

nirvana33 [79]

Answer:

56°, 84°, 3 units

Step-by-step explanation:

Properties of a parallelogram

Two adjacent angles are supplementary
Opposite angles are congruent
Opposite sides are parallel and congruent

Use the properties to find the required parameters

1) Find m∠YXV

m∠YXV + m∠VXW + m∠VWX = 180°
m∠YXV + 40° + 84° = 180°
m∠YXV = 180° - 124°
m∠YXV = 56°

2) Find m∠Y

m∠Y = m∠W = 84°

3) Find x

2x = 6
x = 6/2
x = 3

Prove that at a party where some people shake hands, the number of people who shake hands with an odd number of people is an eve

Kobotan [32]

If there are n people, each person could shake hands with 0 people, 1 person, 2 people,... on up to shaking hands with n − 1
people. Count how many different answers there are to asking the person the question "How many hands did you shake?" How many people are there? If the people are the pigeons, and the possible answers to the question "how many hands did you shake" are the holes, can we conclude anything yet? No? How about now noticing that at least one of the holes "I shook hands with noone" or "I shook hands with everyone" has to be empty... now what?

"Since there are more pigeons than holes there must be a hole with at least two pigeons in the same hole" Now, replace the word "pigeons" and "holes" with the appropriate terms for the context of your specific question, remember we are talking about people and number of handshakes they participated in.
