Stefan sells Jin a bicycle for $125 and a helmet for $18. The total cost for Jin is 130% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally? How much money did he make by selling the bicycle and helmet to Jin?
PLEASE TELL ME AN ANSWER, THIS TEST IS DUE IN 5 MINUTES.
Answer: The selling cost for Stefan bicycle = $114 and
the selling cost of a helmet = $18.
The total cost for Jin is 120% of the money spent.
Let us assume purchasing cost of a bicycle = $x.
Purchasing cost of a halmet = $y.
For bicycle
120% of x is $114
=> 1.20 × x = 114
Dividing both sides by 1.20, we get
x=$95.
For helmet.
120% of y is $18.
=> 1.20 × y = 18.
Dividing both sides by 1.20, we get
y = $15.
Therefore, Stefan spent originally to buy a bike $95 and $15 to buy a helmet.
$114 - 95 = $19
$18 - 15 = $3.
Therefore, he made $19 by selling the bicycle and $3 by selling the helmet to Jin.

Answer:
x = 65
Step-by-step explanation:
straight line = 180 degrees
so
180 - 165 = 25
90 + 25 = 115 degrees
180 - 115 = 65 degrees
so
x = 65

(4n+1)(2n+6) multiply polynomials
Answer:
= 8n^2 +26n +6
Step-by-step explanation:
(4n+1)(2n+6)
= 8n^2 + 24n +2n +6
= 8n^2 +26n +6
The product of the polynomials (4n+1)(2n+6) is 8n² + 26n + 6.
To multiply the polynomials (4n+1)(2n+6), you can use the distributive property.
(4n+1)(2n+6) = 4n x 2n + 4n x 6 + 1 x 2n + 1 x 6
Applying the distributive property and simplifying each term:
= 8n² + 24n + 2n + 6
Combining like terms:
= 8n² + 26n + 6
Therefore, the product of the polynomials (4n+1)(2n+6) is 8n² + 26n + 6.

Answer:
m∡BCA = 57°
Step-by-step explanation:
find 'x' by adding all expressions and setting them equal to 360°
9x+1 + tx+12 + 10x-37 = 360
24x = 384
x = 16
Substitute 16 into 10x-37
160 - 37 = 123
m∡BCA is supplemental with 123°, therefore it measures 57°

The expression showing the number of students in the drama club the next year is 15+d.
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given that, there are 20 students in a drama club,
5 of them will leave in next year, and d students will join,
We are asked to construct an expression to represent the total number of students in the drama club next year.
So, the present number of students in the club = 20
After next year = 20-5 = 15
After the joining = 15+d
Hence the expression showing the number of students in the drama club the next year is 15+d.

So we know that (1+3)/(2+2) is between 1/2 and 3/2 without checking.
(1+3)/(2+2) = 1/1, so we got our first rational number.
Lets continue by finding numbers between 1/2 and 1/1; and 1/1 and 3/2
(1+1)/(2+1) = 2/3
(1+3)/(1+2) = 4/3
We could also look for a number between 1/2 and 2/3 and find
(1+2)/(2+3) = 3/5
And so on, so forth :)
