Step 1: Define
x/5 - 1 = 10
Step 2: Solve for x
Add 1 to both sides: x/5 = 11Multiply 5 on both sides: x = 55A copy machine can print 340 color copies every 8 minutes. Explain or show your reasoning.
A teacher printed 850 copies. How long did it take to print?
Step-by-step explanation:
340=8min
850=?(x)
340x=850×8
340x=6800
x=6800/340
x=20min
so..the teachertook 20 minute to print 850 copies

what is the value of x
Answer:
70°
Step-by-step explanation:
All triangles' angles are added up to 180°
30 + 80 + x = 180
110 + x = 180
x = 180 - 110
x = 70
Answer:
[tex]x = 70[/tex]
Step-by-step explanation:
[tex]x = 180 - (30 + 80)[/tex]
[tex]x = 180 - 110[/tex]
[tex]x = 70[/tex]
to be sure
[tex]70 + 80 + 30 { = }^{?} 180[/tex]
[tex]100 + 80 { = }^{?} 180[/tex]
[tex]180 = 180[/tex]
What is the inverse function of f(x) = x/x-2
9514 1404 393
Answer:
f^-1(x) = 2x/(x -1)
Step-by-step explanation:
You can find the inverse function by solving for y:
[tex]f(y)=x\\\\\dfrac{y}{y-2}=x\\\\x(y-2)=y \qquad\text{multiply by $y-2$}\\\\xy-2x=y \qquad\text{eliminate parentheses}\\\\xy-y=2x \qquad\text{add $2x-y$}\\\\y(x-1)=2x \qquad\text{factor}\\\\y=\dfrac{2x}{x-1} \qquad\text{divide by the coefficient of $y$}\\\\\boxed{f^{-1}(x)=\dfrac{2x}{x-1}} \qquad\text{in functional form}[/tex]

Find the value of x...
Answer:
10x+41=[5+-7]+[2x-2]
we move all terms to left 10x+41-[[5x-7+[2x-2]]=0
Step-by-step explanation:
l calculate terms in parentheses
5x+2x-7-2
we add all the numbers together, and 7x-9 back to the equation -7x-9]
we get ride of parentheses 10x-7+9+41=0 we add all the numbers together,and all 3x+50=0
we move all the terms containg x to the left, all other therms to the right 3x=50
x=-50\3
x-50\3
Which expression is equivalent to this one?
Answer:
The answer is 1
Solve for a. √a−b+c=3
a=9+b−c
a=3+√b−√c
a=3+b−c
a=9+√b−√c
The required solution of the given expression is a = 9 + b- c. Option A is correct.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Given expression
√a−b+c=3
Squaring both sides,
a - b + c = 9
Rearrange the equation in order of a,
a = 9 + b - c
Thus, the required solution of the given expression is a = 9 + b - c. Option A is correct.

A circle has an area of 2290.221. What is the radius? (round to the nearest whole number)
Answer: 27
Step-by-step explanation:
use the formula for the area of circle and solve for r: A=pi r^2
2290.221=pir^2 <---divide by pi
729=r^2 <--- square root both sides
27=r
The first three terms of an arithmetic sequence are as follows. - 7, - 3, 1 Find the next two terms of this sequence
Please help
Answer:
5, 9
Step-by-step explanation:
To obtain the next term in a sequence add the common difference d to the previous term.
d = a₂ - a₁ = - 3 - (- 7) = - 3 + 7 = 4
Thus
a₄ = a₃ + 4 = 1 + 4 = 5
a₅ = a₄ + 4 = 5 + 4 = 9
Data were collected on the following variables. Which variable is LEAST likely to be approximated with a normal model?
A) The distribution of heights of tomato plants growing at an agricultural center, where most heights cluster around the center and there are some very short and very tall heights
B) The distribution of times that a certain brand of house paint lasts on a house, where the distribution is symmetric and bell-shaped
C) The distribution of lengths of the trout living in a certain stream, where the distribution is unimodal and clustered around the center, and the left half is a mirror image of the right half
D) The distribution of weights of mold samples growing in a laboratory, where the distribution is symmetric, unimodal, and does not have any outliers
E) The distribution of ages, in years, of all the residents of a town, where the right tail of the distribution is longer than the left
Answer:
E) The distribution of ages, in years, of all the residents of a town, where the right tail of the distribution is longer than the left
Step-by-step explanation:
Because the distribution is described as having a tail on the right that is longer than the left, it is skewed right and not a normal model.
