Answer:

Step-by-step explanation:
The cost (in dollars) in making b bracelets is represented is

The cost (in dollars) of making b necklaces is

To find how much more it will cost to make b necklaces than b bracelets, we find the difference,




This is a polynomial in descending powers of b, hence it is in standard form;
Answer:
BD = 4.99
Step-by-step explanation:
You can simply use the trigonometric identity tangent to solve for length BD.
Tan = opposite/adjacent
In this case we have,
Tan 31 = 3/BD
BD = 3/Tan 31
BD = 4.99
Answer:
Infinite Solutions
Step-by-step explanation:
If you look at the equation careful you will see this part "-4y+4y". If you see that the variables cancel each other out leaving 2=2. That means that for any value of y, 2=2. Because the variable cancels itself out it doesn't mater what the variable is. So there is an infinite amount of values you can have for "y".
−3(n+3)−10(8n+9)
(−3)(n)+(−3)(3)+(−10)(8n)+(−10)(9)
=−3n+−9+−80n+−90
=−3n+−9+−80n+−90
=(−3n+−80n)+(−9+−90)
=−83n+−99 <- ANSWER
1) Convert 1 and 3/4 to an improper fraction. Use this rule A b/c= a*c+b over c
5 x 1*4+3 over 4
2) simplify 1*4 to 4
5 x 4+3 over 4
3) simplify 4+3 to 7
5 x 7/4
4) simplify
35/4
5) Convert to mixed number
8 and 3/4
