The Cost C (in dollars) of making n bracelets is represented by C=45n+125. How many bracelets are made when the cost is $845?
So we know the cost is $845, which means this is the cost or our C. Lets input this into our equation and solve.
845 = 45n + 125.
Subtract from both sides:
845-125 = 45n + 125-125
720 = 45n
Divide by 45:
720 / 45 = 45n / 45
16 = n
This means that 16 bracelets can be made if the cost is 845.
We can also re-input the information into the equation to be extra sure!
845 = 45 (16) + 125.
845 = 720 + 125.
845 = 845
Yes!
I hope this helps! :)

what is 159,095 rounded to the nearest hundred?
Answer:
159,100 is the answer
Step-by-step explanation:
159,100 is the answer because 159,095 is closest to 159,100 than 159,000. So therefore, 159,100 is the answer.
Answer:
159,100
Step-by-step explanation:
200,000 - rounded to the nearest hundred thousands
160,00 - rounded to the nearest ten thousands
159,00 - rounded to the nearest thousands
159,100 - rounded to the nearest hundreds
159,100 - rounded to nearest tens
159,095 - rounded to nearest ones
While rounding off to the nearest hundred, if the digit in the tens place is between 0 – 4 i.e. < 5, then the tens place is replaced by ‘0’.
If the digit in the units place is equal to or >5, then the tens place is replaced by ‘0’ and the hundreds place is increased by 1.

A motorboat moves across a lake at a constant speed. When it begins, it is 55 km from the shore. After 12 minutes, it is 19 km from the shore. Which function describes the motorboat's distance from the shore?
A. y = –12x + 19
B. y = –3x + 55
C. y = 3x + 55
D. y = –12x + 55
Answer:
y= _3x+55
Step-by-step explanation:
we conqet two points
(0,55) (12,19)
55=B subsiquent two points into the equation
19=a,12+55
a=-3
b=55
so we choose B

A. 5
B. 14
C. 27
D. 38
Answer:
14
Step-by-step explanation:
Answer:
14
Step-by-step explanation:
Solve for x.
4 (x + 1 1/3) = 9 2/3
Enter your answer as a mixed number in simplest form.
Answer:
x = 13/12
x = 1 1/12
Step-by-step:
4 (x + 1 1/3) = 9 2/3
4x + 5 1/3 = 9 2/3
subtract 5 1/3 from each side
4x = 4 1/3
divided by 4 on each side
x = 13/12
x = 1 1/2

Answer: Alright i know exactly how to do this :) i need ur help though it's been a bit since i did this the types they are asking for what are they?
I need a multiple choice otherwise i dunno how to help with identifying them
The math is simple tho
16x-2=15x+4
add 2 to -2 to elimate itself add 2 to +4 =6
16x=15x+6
we need x by itself subtract 15x from itself and then 16x
1x=+6 = x is 6
The rest go the same-
Step-by-step explanation:
Solve for x.

A system of equation is shown.
5x+2y=245
y=x+6
Enter a numeric value to complete the solution of the system.
Answer:
y = 245 / 7, x = 29
Step-by-step explanation:
make both into ax + by = c format which is
Math:
5x + 2y = 245
-5x + 5y = 30 <== 5 (- x + y = 6) to cancel out the x since it has a negative already.
[(Side Note) if both were positive then you would need to do
EX: - 5 (- x + y = 6)]
Continued:
7y = 275 ==> 7y/7 = 245/7
y = 245 / 7
Plug it in the most convenient one which has the equation y = x + 6
and tweak it a bit
x = y - 6
x = 245 / 7 - 6 ==> 245 / 7 - 42 / 7
x = 203 / 7 ==> 29
help pls and letter d is 4 1/2
Answer: The answer is B.
Step-by-step explanation:
To figure out, you must first turn the mixed fraction (3 1/2) into an improper fraction (7/2). We can do so by:
3 * 2 = 6
6 + 1 = 7 or 7/2
Next, you follow the rules of KCF: Keep, Change, Flip. Keep the first fraction, Change the sign to its inverse operation, and Flip the second fraction.
Our original equation is 7/2 /(divided by) 3/2 = ?
1. Keep the first fraction
7/2 / 3/2 = 7/2 / 32
2. Change the sign to its inverse operation
7/2 / 3/2 = 7/2 * 3/2
3. Flip the second fraction
7/2 * 3/2 = 7/2 * 2/3
Now, solve.
7/2 * 2/3
7 * 2 / 2 * 3 = 14/6
To make this a proper mixed number, first simplify.
14/6 / 2 = 7/3
Now, figure out how many wholes are in 7/3.
7/3 / 3 = 2 1/3
This is because 2 times 3 is six, and 7 minus 6 equals 1, or 1/3.
Therefore, the answer is 7/3 OR 2 1/3 OR B

The open side of the inequality sign indicates the larger number. So 5 > 3, 4 < 6.
This, ≥, means it is bigger than or equal.
To show < or >, the purple arrow points to where the unknown value (x or n or k or b etc.) could be, and the dot is unfilled, or white, indicating that number is not a possible value of the unknown number.
To show ≤ or ≥, the purple arrow works the same way, it points to the where the unknown value could be. But the dot is filled, showing that the number could be the unknown value.
So for question 11, the answer is x ≤ 0 (x is less than or equal to zero).
For question 12, the answer is x > 3 (x is more than three)
Hope this helped :)
