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)

Explanation:
I believe you have the equations wrong. 1 equation you can use is t=15d, and the other equation you can use is d=t/15. then if you plug 7.5 for d in one of the equations you can get the answer

Explain the relationship between a strategy, such as number sense, and a written method , such as partial products or area models , for multiplying decimal number's.
Answer:
Hello
Step-by-step explanation:
You can take away the decimals
for example 0.33 x 0.7
do 33 x 7
which is 231
the 0.33 has 2 decimal spaces because there are 2 digits after the point
0.7 has 1 decimal place because there is 1 digit after the point.
so in total, there is 3 decimal
because you do 2 + 1
3
from the left, you count backwards and add the decimal point
the final answer should be 0.231
hope it helped

Question
A map of a farm is shown in a coordinate plane in which the coordinates are measured in yards. The map shows the barn at (-5, 4). A well is dug at (-5, y). What are two values of y such that the barn is 30 yards from the well?
Answer:
y-34 or y-30
Step-by-step explanation:
Use the distributive property & multiply the 2x + 3 inside the parenthesis using the 4 outside the parenthesis.
Then, multiply them to both sides, to get . (8x+12) = yDistribute by multiplying y with 8x + 12 using the distributive property.Your final result will be 8xy + 12y / 5Learn more about distributive property here: brainly.com/question/2807928

HELP PLZ ND THX U?!?!?!?!?!?!?!?!?!
Answer:
U = 1
Answer = 6
Step-by-step explanation:
We can do really any number. But in this case, we are gonna do 1. So, it would look like (7 x 1) - 1. It would look like that because we know that 7u is equal to 7 times U or in this case, 7 times 1. So, we know 7 x 1 is 7. Now, we do 7 - 1 since U = 1, and we get our answer of 6.

Mr. Reynolds is a rancher. He started with a 150 cows in his herd. Due to a hole in his fence, he now has 120 cows in his herd. By what percentage was the number of cows in Mr. Reynold's herd reduced?
Answer:
20%
Step-by-step explanation:
Therefore, the percentage of the number of cows in Mr. Reynold's herd reduced is [tex]20[/tex] %.
What is the percentage?
A percentage is a number or ratio expressed as a fraction of [tex]100[/tex]. It is often denoted using the percent sign, "%".
Here given that,
Mr. Reynolds is a rancher. He started with a [tex]150[/tex] cows in his herd. Due to a hole in his fence, he now has [tex]120[/tex] cows in his herd.
Number of cows Mr. Reynolds have
[tex]\frac{120}{150}[/tex] ×[tex]100=80[/tex] %
So, the number of cows Mr. Reynolds reduced is
[tex]100[/tex] % - [tex]80[/tex] % = [tex]20[/tex] %
Hence, the percentage of the number of cows in Mr. Reynold's herd reduced is [tex]20[/tex] %.

Write the Pythagorean theorem equation in an equivalent form with the a² isolated.
Answer:
[tex]a^{2}= -b^{2}+c^{2}[/tex]
Step-by-step explanation:
Rewrite the Pythagorean Theorem equation in terms of [tex]a^{2}[/tex].
[tex]a^{2}+b^{2}=c^{2}[/tex]
Subtract b squared from both sides.
[tex]a^{2}= -b^{2}+c^{2}[/tex]
Answer:
A^2=-B^2+H^2
Step-by-step explanation:
A^2+B^2=H^2
Isolate A^2. Subtract B^2 from both sides.
A^2=-B^2+H^2

S - How many positive integers are between - 7/3 and 5/2?
E. 0
F. 1
G. 2.
H. 3
Answer:
The positive integers between -7/3 and 5/2 are 1 and 2.
Step-by-step explanation:
"How many positive integers are between - 7/3 and 5/2?" can be written as "How many positive integers are between - 2 1/3 and 2 1/2?" This rewriting makes it easier to identify the positive integers in question. They are 1 and 2.
The number of positive integers between -7/3 and 5/2 is 3 (option H).
To determine the number of positive integers between -7/3 and 5/2, we need to find the positive integers greater than -7/3 and less than 5/2.
Converting -7/3 to a decimal, we have:
-7/3 ≈ -2.333
Converting 5/2 to a decimal, we have:
5/2 = 2.5
Now, let's check which positive integers lie between -2.333 and 2.5.
The positive integers greater than -2.333 and less than 2.5 are 0, 1, and 2.
Therefore, there are three positive integers between -7/3 and 5/2. The correct answer is option H. 3.

Please explain I am very confused!
Answer:
42°
Step-by-step explanation:
Altitude of an isosceles triangle divides it vertex in equal angles
so ∠ABD = ∠PBC = 48/2 = 24
In ΔABC sum of angles = 180 and ∠A = ∠C
48 + A + C = 180
2A = 180 - 48 = 132
A = 132/2 = 66 = ∠C
As PB = PC ---> ∠PBC = ∠PCB = 24
∠ACB = 66 = ∠PCD + ∠PCB
66 = ∠PCD + 24
∠PCD = 42

2. yes; the equation can be written as y = kx; k = 1
Step-by-step explanation:
x-y = 0
That means x and y have to be the same value.
