Answer:
The number of watches made is 8
Step-by-step explanation:
SO the equation is C=15n+85 where C is the total cost and N is the amount of watches
1)plug in C
385=15n+85
2)move 85 to the other side so it would become -85
385=15n+85 → 385-85=15n → 100=15n
3)divide 15 from both sides
100/15=15n/15 → 25/3=n
since the number of watches can't be a fraction, we round to the lowest number which is 8(24/3)

pls help me with this problem i will give brainly.
Answer:
We are given that:
variables x and y vary directly, this means that:
y = kx where k is the constant of proportionality
Now, we are also given that:
y = 45 at x = 40.
We will use these values and substitute in the above relation to get k as follows:
y = kx
45 = 40k
k = 45/40 = 9/8 = 1.125
Based on the above calculations, the equation that relates x and y is:
y = 1.125x

Emily has fixed monthly expenses that are taken directly out of her bank account.
Emily wants to know how much money she must deposit in her account each month to cover these expenses.
How can Emily use an additive inverse to find this amount?
Answer:
Emily must deposit each month.
Step-by-step explanation:
As you know that Additive inverse of any number
A = - A, For example additive inverse of 2 is - 2
or additive inverse of (-2) is 2.
Now, According to the question given
Emily has fixed monthly expenses that are taken directly out of her bank account.
As she wants to know, how much money she must deposit in her account each month to cover these expenses.
So, Expenses are Additive inverse of Deposit or Deposit are additive inverse of Expenses.
Out of the given Options Option D which is, Emily can add (-48) + (-12) + (-44) to find her total expenses. The additive inverse of this number is the amount Emily must deposit each month. is correct

x5=−0.92
What is the solution to the equation?
Enter your answer as a decimal in the box.
Answer:
-4.6
Step-by-step explanation:
Given the equation [tex]x5 = -0.92[/tex] isolate [tex]x[/tex] by multiplying 5 in both sides of the equation.
[tex]5\cdot\frac{x}{5} = -0.92\cdot5 \\x = -4.6[/tex]
x − (−2/3) = 1.06
Enter your answer as a fraction in simplest form.
Answer:
x = 3.18/2
Step-by-step explanation:
x - (-2/3) = 1.06
x + 2/3 = 1.06
3/2 * 2/3 + x = 1.06 * 3/2
x = 3.18/2

What additional information is required to prove the triangles are congruent using ASA?
Since vertical angles are congruent assume:
Answer:
C
Step-by-step explanation:
We already have one angle form the question that leaves us with one other angle and one side that we need to find, since we are required to use ASA or angle-side-angle.
the diagram gives us 2 congruent sides UB and AB since they have a similar slash on both of them, finally we need one more angle, so we look at the choices we have:
a) it gives us congruent sides not angles, so we move to the next
b) same thing as A
c) gives us 2 congruent angles, and since these are 2 new angles not given in the question, they can work
d) these 2 angels are the same 2 given in the question, so we can't use them.

=========================================================
Explanation:
The symbol that looks like an "E" is the uppercase greek letter sigma. It's used for summation. Specifically we are adding terms of the form -4+5n. What we do is replace n with values from the set {2,3,4,...,9,10}. After evaluating each item, we add up the results to get our final answer.
If n = 2, then -4+5n = -4+5*2 = 6 which is the first term.
If n = 3, then -4+5n = -4+5*3 = 11 is the second term
and so on until you reach n = 10.
A table is a handy way to keep track of everything (see below). Adding everything in the second column leads to the final answer of 234.

what is bigger 5.62 or 5.5
Answer:
5.62
Step-by-step explanation:
5.62 is bigger than 5.5
5.62 is bigger by 0.12
You can prove this by subtracting 5.5 from 5.62
If you were to subtract 5.62 from 5.5 you'd end up with a negative number, so obviously 5.62 is bigger

You have 8 cups of flour. It takes 1 cup of flour to make 24 cookies. The function c(f) = 24f
represents the number of cookies, c, that can be made with f cups of flour.
What domain and range are reasonable for the function?
What do the x-intercept and y-intercept of the graph above represent in this situation?
Answer:
y = c(f) = 24x so range is 24 domain is 1 the x intercept and y intercept do not count as an adding value in the equation so in order for y = c(f) = 24x we need to make x a condition that x=1 and therefore x represents 1
Step-by-step explanation:
Given (1, 24) (8, c(f)) = 24 (8) = 192 = (1, 24) (8, 192) Then use formula y2-y1/x2- x1 = 192-24/ 8-1 = 168/7 = 24 slope = 24 equation = (f) = 24x The domain is all values of x that give real numbers as answers, and that is everything except 0, since 1/0 is illegal The range is all the values of y that can be reached from real values of x.
Answer:
y = c(f) = 24x so range is 24 domain is 1 the x intercept and y intercept do not count as an adding value in the equation so in order for y = c(f) = 24x we need to make x a condition that x=1 and therefore x represents 1
Please help me solve this: y=8x 4x+y=48
Answer: x=4, y=32
Step-by-step explanation:
y=8x
4x+y=48
Plug in 8x for y in the equation
4x+8x = 48
Add like terms
12x= 48
Divide both side by 12
12x/12=48/12
x= 4
Then plug 4 back into the original equation in place of x
4(4)+y=48
16+y=48
Minus 16 from both sides
y= 48-16
y= 32
Answer: (4,32)
Answer: x = 4
Step-by-step explanation: 48 divided by 12 = 4
4 x 4 = 16
Y = 8x
8 x 4 = 32
32 + 16 = 48
