Answer:
8 dimes and 6 quarters
===================================================
Work Shown:
d = number of dimes
q = number of quarters
d+q = 14 since this is his coin total; equation solves to d = 14-q
10d+25q = 230 which is the total value in cents
10(14-q)+25q = 230 .... apply substitution rule
140-10q+25q = 230
15q+140 = 230
15q = 230-140
15q = 90
q = 90/15
q = 6 = number of quarters
d = 14-q
d = 14-6
d = 8 = number of dimes
-----------------
Check:
8 dimes + 6 quarters = 14 coins
8 dimes = 8*10 = 80 cents
6 quarters = 6*25 = 150 cents
8 dimes + 6 quarters = 80 cents + 150 cents = 230 cents = $2.30

East High School had a total of 12,510 people in
attendance during their 15-game soccer season. West
High School had a total of 14,310 people for 18 games.
On average, which school had a greater number of
people watching per game? How much greater?
On average East high school had a greater number of people watching per game that is, 834 > 795.
What do we mean by average?An average, which is frequently the sum of the numbers divided by the total number of the numbers in the group, is a single number that is selected to describe a group of numbers in simple English.For example, the average of the numbers 2, 3, 4, 7, and 9 is 5.The ratio obtained by dividing the total number of figures in a set by the total number of figures is known as the average.An average test score of 85 could represent the simple average or a result that lies halfway between two extremes.So, schools with a greater number of people matching the match per game:
Each high school:
12510/15834West high school:
14310/18795So, 834 > 795 which means Each high school > West high school.
Therefore, on average East high school had a greater number of people watching per game that is, 834 > 795.

What is the slope of the line tangent to the graph of y= (x^2 -2)/(x^2 + 1) when x =1
Step-by-step explanation:
first find the derivative and then substitute x=1
d/dx((x^2 -2)/(x^2 + 1)) = (2*x)/(1+x^2)+(4*x)/(1+(2*x^2)+x^4)+(-2*x^3)/(1+(2*x^2)+x^4)
substitute x=1
check the image above
slope = 1.5
The slope of the line tangent when x = 1 is 1.5.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 9 is an equation.
We have,
y = (x² - 2)/(x² + 1)
y' = [(x² + 1)(2x) - (x² - 2)(2x)] / (x² + 1)²
Put x = 1
dy/dx = [(1² + 1)(2) - (1² - 2)(2)] / (1² + 1)²
dy/dx = (4 + 2)/4
dy/dx = 6/4 = 3/2 = 1.5
Thus,
The slope is 1.5.

Two supplementary angles differ by 44 degrees. Find the angles
Answer:
hope it helps and u understand
check the steps in picture attached
Two supplementary angles equal 180 degrees:
Subtract the difference:
180-44 = 136
Divide that by 2:
136/2 = 68
One angle is 68 degrees
The other angle is 68 + 44 = 112 degrees

What is the sum of the first seven terms of the geometric series? 3 12 48 192. 4,372 12,288 16,383 65,535.
The addition of the first seven terms of the geometric series is 16383.
First term = 3
Second term = 3 × 4 = 12
Third term = 12 × 4 = 48
Fourth term = 48 × 4 = 192
Fifth term = 192 × 4 = 768
Sixth term = 768 × 4 = 3072
Seventh term = 12288
Addition of the terms = 16383
In conclusion, the correct option is 16383.

Brent earns $10 for every car he washes and $15 for every lawn he mows. Let x represent the number of cars he washes and y stand for every lawn he mows.
Which expression represents the total money Brent will earn washing cars and mowing lawns?
15x+10y15 x plus 10 y
15y+10x15 y plus 10 x
15+10(xy)15 plus 10 times x y
10+15(xy)
ill be happy if i get a proper answer thank you
Answer:
The expression that represents the total money Brent will earn is the second option or 15y + 10x because y is the number of lawns he mows and he earns $15 for every lawn he mows and x is the number of cars he washes and he earns $10 for that.

Two fractions can be easily added together when they
have a common denominator.
a. What is one denominator you could use to add the
following two fractions?
3 1
-+
8 12
Answer:
One denominator you could use to add the two fractions 3/1 and 8/12 is 12.
Step-by-step explanation:
When adding the fractions 3/1 and 8/12, the first step is to multiply both the numerator and denominator by the same number until you end up with common denominators. Here, the best thing to do is multiply both 3 and 1 by 12 which ends in 36/12; from that point on, you just do the simple math of 36/12 + 8/12.
