Answer: Alright So, A bag is filled with green and blue marbles. There are 48 marbles in the bag. If there are 38 more green marbles than blue marbles, find the number of green marbles and the number of blue marbles in the bag.
------
Equations:
g + b = 48 marbles
g = b + 38
------
Substitute for "g" and solve for "b"::
b+38 + b = 48
2b = 10
b = 5 (# of blue marbles)
g = b+38 = 43 (# of green marbles)

Find the value of x in the diagram below.
A. -8
B. 8
C. 98
D. 172
Answer:
x =9 and none of the choices are right as stated above
Step-by-step explanation:
Since 11x + 11 and 110 degrees are vertical angles, the two angles are congruent.
Therefore,
11x + 11 = 110 1. Subtract both sides by 11
11x = 99 2. Divide both sides by 11
x = 9

Find the 84th term of the arithmetic sequence 18, 31, 44, ...
Answer:
common difference = 31-18
common difference =13
from,
An=A1 +(n-1)d
A84=18+(84-1)13
A84=1097
Answer:
1097
Step-by-step explanation:
Common Difference:
d=a_2-a_1=(31)-(18)=13
d=a

A teacher surveyed her class after they had taken a vocabulary test. Eighteen of the students claimed they had studied at least one hour for the test. The remaining twelve students admitted that they had not studied for the test at all. The test results (expressed as a percent) for the two groups are shown below.
Studied: 88, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 84
Did Not Study: 82, 72, 45, 91, 58, 83, 65, 87, 90, 77, 73, 89
Which of the following statements are true?
There is no mode of the group that studied.
In general, those students that studied scored much higher than those students that did not study.
The mean of the group that studied is over 15 percentage points higher than the mean of the group that did not study.
The median of the group that studied is over 95.
The median of the group that did not study is less than 80.
Answer:

A goalie makes 12 saves in 4 games. What is the unit rate of saves per game?
Answer:
3 saves per day
Step-by-step explanation:
Since we are finding the number of saves per day, our first dividor will be the number of saves, then we divide by the other number. We have 12 saves in total, and four games, so we will have to divide.
12 divided by 4 is equal to 3.
The answer to the question must be 3.
Answer:
12 saves/ 4 games = 3 saves/ 1 game = 3 saves per game
Step-by-step explanation:
A ration is basically a division problem. Divide until you get a denominator of 1.
12/ 4 = 3/ 1
So, if he makes 12 saves in 4 games, then he makes 3 saves per game.

For each one-year period after a car was purchased, its value at the end of the year was 17% less than its value at the beginning of the year. State whether the value of the car as a function of time after it was purchased is best modeled with a linear function, a quadratic function, or an exponential function and explain why. Enter your answer and your explanation in the space provided. If the value of the car 2 years after it was purchased is $17,842.51, what was the value of the car when it was purchased?
Answer:
The value of the car as a function of time after it was purchased is best modeled with an exponential function.
The Value of car when it is purchased = $25,900
Step-by-step explanation:
As given,
The value at the end of the year was 17% less than its value at the beginning of the year.
⇒ value at the end of the year = (100% - 17% ) = 83% of value at the beginning of the year.
Now,
Let the Value of car when it is purchased = x
So,
Price at the end of 1 year = 83% of x = 0.83x
Price at the end of 2 year = 83% of 0.83 x = (0.83)² x
Price at the end of 2 year = 83% of (0.83)² x = (0.83)³ x
and so on
Price at the end of n years = (0.83)ⁿ x
∴ we get
The value of the car as a function of time after it was purchased is best modeled with an exponential function.
Now,
Value of car after 2 year = (0.83)² x = $17,842.51
⇒0.6889x = $17,842.51
⇒x = [tex]\frac{17,842.51}{0.6889}[/tex] = $25,900
∴ we get
The Value of car when it is purchased = x = $25,900
