Seven friends have similar cell phone plans. The price of each plan is $x. Three of the seven friends pay an extra $4 per month for unlimited text messaging. Write and simplify an expression that represents the total cost of the seven plans. (Provide expression in simplest form)
Answer: 7x + 12
Step-by-step explanation:
The price of each plan = $x
Since three of the seven friends pay an extra $4 per month for unlimited text messaging, the cost of the three friends will be:
= 3(x + 4)
The cost if the other four friends will be:
= 4 × x
= 4x
Therefore, the total cost of the seven plans will be:
= 4x + 3(x + 4)
= 4x + 3x + 12
= 7x + 12

Answer:
Option (2)
Step-by-step explanation:
HL theorem for congruence states that if hypotenuse and one leg of one right triangle are congruent to the corresponding sides of the of the right triangle, both the triangles will be congruent.
By this theorem,
ΔACB ≅ ΔFED
If AB ≅ DF [Hypotenuse]
AC ≅ EF [Leg]
By these properties,
AC = EF = 12
Or BC = DF = 28
Therefore, Option (2) will be the correct option.
Given point P(9,-11), what are the coordinates of P' after a 180⁰ rotation?
(9,11)
(-9,11)
(-11,-9)
(11,9)
Answer:
-9,11
Step-by-step explanation:
The negative signs get flipped so if the number was positive it would become negative and vice versa.
Answer:
(-9,11)
Step-by-step explanation:
180 Degree Rotation
When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative.

A scatterplot is produced to compare the number of hours that students study to their test scores. There are 25 data points, each representing a different student. The scatterplot shows a grouping of points rising from left to right. Which statement could be true?
The question is incomplete, the complete question is;
A scatterplot is produced to compare the number of hours that students study to their test scores. There are 25 data points, each representing a different student. The scatterplot shows a grouping of points rising from left to right. Which statement could be true?
a. There is no relationship between the number of hours that students study and their test scores because the scatterplot does not have a cluster.
b. As the number of hours of studying increases, test scores decrease because the scatterplot has a cluster that increases from left to right.
c. As the number of hours of studying increases, test scores increase because the scatterplot has a cluster that increases from left to right.
d. The number of hours that students study is equal to the test scores because the scatterplot does not show a cluster.
Answer:
c. As the number of hours of studying increases, test scores increase because the scatterplot has a cluster that increases from left to right.
Step-by-step explanation:
Though we can't see the scatter plot but it makes sense from option c that as the number of hours of studying increases, test scores increase.
That option even stated that the cluster of points increases from left to right. If the scatterplot has a cluster that increases from left to right, then it follows that the test scores actually increases positively with the number of study hours.

Please help me I’m working on a math test and I’m struggling with this problem: The Aon center in Chicago is one of the worlds tallest buildings. It was built in 1973. It is 1,136 feet high and has 80 stories. If each story is of equal height, how tall is each story btw this is division (:
Answer:
They are 14.2 feet high each
Step-by-step explanation:
1136/80=14.2
Answer:
14.2 feet
Step-by-step explanation:
We know that the height of the Aon Center is 1,136 feet.
This building has 80 stories whose heights are equal.
Therefore, in order to calculate the height of each story, we must divide the height of the Aon Center by the number of stories it has.
Arnold has $24 to spend at the movies. His ticket is $12. He bought popcorn, candy bar, and soda. Popcorn is double the prize of the soda. The soda and candy bar are same prize. How much did he pay for the soda?
Given:
Arnold has $24 to spend at the movies.
Ticket = $12
Popcorn is double the price of the soda.
The soda and candy bar are same price.
To find:
The price for the soda.
Solution:
Let x be the price of soda.
According to the question,
Price of candy = Price of soda = x
Price of popcorn = 2(price of soda) = 2x
Total amount = Ticket + Popcorn + Soda + Candy
[tex]24=12+2x+x+x[/tex]
[tex]24=12+4x[/tex]
[tex]24-12=4x[/tex]
[tex]12=4x[/tex]
Divide both sides by 4.
[tex]\dfrac{12}{4}=x[/tex]
[tex]3=x[/tex]
Therefore, the price of soda is $3.

What is the solution of the system? Use elimination. 5x = -30 + 5y 20y = 105 + 5x 0 (-1,4) D5, 20) KO (-1, 5) (5.-1)
First, we will use elimination to solve for y.
[tex]5x = -30 + 5y\\20y = 105 + 5x\\\\5x - 5y = -30\\-5x + 20y = 105\\\\15y = 75\\\\y = 5[/tex]
Now, we will use what we got for y to solve for x.
[tex]5x = -30 + 5(5)\\\\5x = -30 + 25\\\\5x = -5\\\\x = -1[/tex]
Solution:
[tex](-1, 5)[/tex]

If lines BG and CF are parallel, then JOL and IOM and congruent triangles. Is this statement correct? Explain your answer.
Answer:
No this statement is not correct.
Step-by-step explanation:
The definition of congruent triangles are triangles with equal side lengths and equal angles. As we can see in the picture, one triangle is significantly larger than the other, so in conclusion, the statement is incorrect.
By basic definition of congruent triangles we can say that the statement
"triangle JOL and IOM and congruent triangles" is false
what are congruent triangles?Triangle with same shape and same size are known as congruent triangle .Corresponding sides and angles of congruent triangles are equal .
Here in the given diagram it is clearly visible that size of triangle IOM and JOL is not same so they can't have same length of sides ,although corresponding angles are equal because of properties of parallel lines but for congruent triangles it's necessary that both corresponding sides and angle are equal .

PLEASE HELP! A tank containing 35 gallons of water is leaking at a rate of 1/4 gallon per minute. Write an expression to determine the number of gallons left in the tank after m minutes. Thank you!
Answer:
35 - m is the expression used to determine the number of gallons left in the tank after m minutes.
Step-by-step explanation:
Given:
Tank with 35 gallons of water is leaking at a rate of gallon per minuteCalculations:
Let "m" represent the number of minutes spent Number of gallons left in the tank = initial amount of water present – leaked amount of water [tex]=35-m * 1=35-m[/tex] The required expression is 35 – mwhat is the value of x in the
triangle?
Answer:
x = 75°
Step-by-step explanation:
Sum of angles in a triangle: 180°
So,
50°+55°+x=180°
105°+ x = 180°
Subtract 105° from both sides
x = 75°
