Answer:
C. 7x-200=17700
Step-by-step explanation:
When you write an equation for the middle and lower row you can add them together to get 6x+200=1700 but you still must include the upper row so you add x which results in c. If you solve you get x=2500 and if you plug that back into you equations for the lower and middle rows and then add the upper row you get 17700.
Answer:
7x+200=17,700 because if you set up an equation for each level, the upper level is just x, the middle level is 2x=500, and the lover level is 4x- 300. if you add all 3 equations together and set it equal to 17,700, it equals 7x+200=17,700

herself to some chocolates. Zoe ate 4 chocolates each night and after 3 nights, there
were 12 chocolates remaining in the box. Write an equation for C, in terms oft,
representing the number of chocolates remaining in the box t days after Zoe's
birthday.
Answer:
c=-3t+30
Stay safe
The expression for the number of chocolates remaining will be c = 24 - 4t.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that, Zoe was given a box of assorted chocolates for her birthday. Each night, she to some chocolates. Zoe ate 4 chocolates each night and after 3 nights, there were 12 chocolates remaining in the box.
Let the number of days be represented by t, and the number of chocolates will be C.
The total number of chocolates will be calculated as,
Total = 3 x 4 + remaining chocolates = 12
Total = 3 x 4 + 12
Total = 12
The expression will be written as,
C = 24 - 4t
Therefore, the expression for the number of chocolates remaining will be c = 24 - 4t.

Negative StartFraction 11 Over 2 EndFraction
Negative StartFraction 11 Over 8 EndFraction
StartFraction 11 Over 8 EndFraction
StartFraction 11 Over 4 EndFraction
Answer:
B. -11/8
Step-by-step explanation:
Given:
tan m = ½
tan n = -6
Required:
Exact value of tan(m + n)
Solution:
Find m and n:
[tex] tan (m) = \frac{1}{2} [/tex]
[tex] tan (m) = 0.5 [/tex]
[tex] m = tan^{-1}(0.5) [/tex]
m = 26° (approximated)
[tex] tan (n) = -6 [/tex]
[tex] n = tan^{-1}(-6) [/tex]
n = -80° = 280° (i.e. 360 - 80)
Exact value of tan(m + n) = tan(26 + 280)

What is the domain of the radical function shown on the graph?
The domain is the set of all possible x inputs. The blue curve stretches on forever in both directions along the x axis. This means that we can plug in any x value we want, and get some y output. We don't have to worry about dividing by zero, or applying the square root of a negative number, so there are no restrictions on the domain. We can take the cube root of a negative number with no issues. For example, the cube root of -8 is -2.

Answer:
angle SVR = 30°angle PVR = 90°angle SVQ = 60°angle SVP = 120°angle RVQ = 30°Step-by-step explanation:
As with finding distances on a number line, the easiest way is to subtract the smaller coordinate from the larger. Here, the "number line" is the arc at the edge of the protractor. The corresponding coordinates are ...
S: 40°
R: 70°
Q: 100°
P: 160°
The measure of an angle with its vertex at V will be the difference between the "coordinates" of the endpoints of the arc it intercepts. That is ...
m∠SVR = "R" - "S" = 70° -40° = 30°
The other angles are found the same way:
m∠PVR = 160° -70° = 90°
m∠SVQ = 100° -40° = 60°
m∠SVP = 160° -40° = 120°
m∠RVQ = 100° -70° = 30°

a = 10
Step-by-step explanation:
Multiply both sides by 12
[tex]\frac{a}{12}[/tex] = [tex]\frac{5}{6}[/tex]
[tex]\frac{12a}{12}[/tex] which cancels out because it's 1
[tex]\frac{5 * 12}{6}[/tex] = [tex]\frac{60}{6}[/tex]
a = 10

What is a function?A relation between a collection of inputs and outputs is known as a function. A function is a connection between inputs in which each input is connected to precisely one output. Each function has a range, co-domain, and domain.
Given function:
f(x) = 4
To find the input value of x;
Let the function,
y = f(x)
4 = f(x)
That means, y = 4.
From the attached graph;
We interpreted two values
x = -1 and 9 where f(x) = 4
Therefore, -1 and 9 are the values.
