The expression which is equivalent to the provided complex fraction is equal to the expression,
[tex]{\dfrac{-4x+7}{2(x-2)}}[/tex]
What is the equivalent expression?Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.
The expression given in the problem is,
[tex]\dfrac{\dfrac{3}{x-1}-4}{2-\dfrac{2}{x-1}}[/tex]
Let the expression which is equivalent to the above expression is f(x). Therefore,
[tex]f(x)=\dfrac{\dfrac{3}{x-1}-4}{2-\dfrac{2}{x-1}}[/tex]
Take the LCM (x-1) in the numerator and denominator as,
[tex]f(x)=\dfrac{\dfrac{3-4(x-1)}{x-1}}{\dfrac{2(x-1)-2}{x-1}}[/tex]
Simplify the expression and cancel out the (x-1) from both the fraction as,
[tex]f(x)={\dfrac{3-4(x-1)}{2(x-1)-2}}\\f(x)={\dfrac{3-4x+4}{2x-2-2}}\\f(x)={\dfrac{-4x+7}{2(x-2)}}[/tex]
Hence, the expression which is equivalent to the provided complex fraction is equal to the expression,
[tex]{\dfrac{-4x+7}{2(x-2)}}[/tex]

Suppose a rescue helicopter is 700 feet above sea level descends 300 feet to search for debris or any other signs of a submarine in trouble. When the captain does not see anything, he ascends 200 feet and stays at that altitude while he tries to get a radio signal from the submarine. A few moments later he speaks to the captain and is informed that the submarine is 122 feet below sea level. How far is the helicopter from the submarine?
Answer:
The helicopter is 722 feet from the submarine.
Step-by-step explanation:
700 - 300 = 400
400 + 200 = 600
600 - 122 = 722

What is a quadratic equation?It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
The equation is given as
[tex]\rm 4\sqrt{5x + 66} = x +10[/tex]
Squaring both sides, we have
16(5x + 66) = (x + 10)²
16(5x + 66) = x² + 100 + 20x
On simplifying, we get
x² + 100 + 20x -80x - 1056 = 0
x² - 60x - 956 = 0
On solving by formula method, we have
a = 1; b = -60; and c = -965
[tex]\rm x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}\\\\\\x = \dfrac{-(-60) \pm \sqrt{(-60)^2 - 4*1*(-965)}}{2*1}\\\\\\x = 73.19, \ -13.19[/tex]
Thus, the solutions of the equation are 73.19 and -13.19.

Amy volunteers at an animal shelter. She worked 10 hours in March, 12 hours in April, 14 hours in May, and 16 hours in June. If the pattern continues, how many hours will she work in December? Make a table to find the answer.
Answer:
28
Step-by-step explanation:
3th (March): 10
4th: 12
5th: 14
6th: 16
7th: 18
8th: 20
9th: 22
10th: 24
11th: 26
12th ( December): 28
The 4th, 5th, 6th ect are the months because i cant remember the order or how to spell rn
March (1) = 10 hours (first month, second month.. so on)
April (2) = 12 hours (+2)
May (3) = 14 hours (+2)
June (4) = 16 hours (+2)
July (5) = 18 hours (+2)
August (6) = 20 hours (+2)
September (7) = 22 hours (+2)
October (8) = 24 hours (+2)
November (9) = 26 hours (+2)
December (10) = 28 hours (+2)
Amy works 2 extra hours every month.
By December, she would have worked 28 hours.
A small-business owner will lease a billboard to advertise her business. The table shows the linear relationship between the cost of leasing a billboard from Company N and the number of months the billboard is leased. The cost to lease a billboard from a different company, Company P, for x months can be found using P(x) = 100x. For what number of months will the cost of leasing a billboard be the same for both companies?
Number on months, x. - Cost, N
1 - 580
2 - 660
3 - 740
4 - 820
5 - 900
RoC = + 80
A. 9 months
B. 29 months
C. 10 months
D. 25 months
It would take about 25 months for the cost of leasing a billboard be the same for both companies.
Linear functionA linear function is in the form:
y = mx + b
Where y,x are variables, m is the rate of change and b is the initial value of y.
Let P represent the cost to lease a billboard from a different company for x months. Given that:
P(x) = 100x
For the second company, let C represent the cost, hence using the table point (1, 580) and (5, 900):
C - 580 = [(900 - 580)/(5 - 1)](x - 1)
C = 80x + 500
For the same cost:
100x = 80x + 500
x = 25 months
It would take about 25 months for the cost of leasing a billboard be the same for both companies.

Solve the system of equations
a+s=560
8a+3s=2905
Answer:
a=245 s=315
Step: Solve a+s=560 for a:
a+s=560
a+s=560(Add -s to both sides)
a=−s+560
Step: Substitute −s+560 for a in 8a+3s=2905:
8a+3s=2905
8(−s+560)+3s=2905
−5s+4480=2905(Simplify both sides of the equation)
−5s+4480=2905(Add -4480 to both sides)
−5s=−1575
−5s=−1575(Divide both sides by -5)
s=315
Step: Substitute 315 for s in a=−s+560:
a=−s+560
a=−315+560
a=245

Answer:
49π cm²
Step-by-step explanation:
Diameter (d) = 14 cm
Radius (r) = d/2 = 14/2 = 7 cm
Area of a circle
= πr²
= π × (7)²
= 49π cm²
Hope it helps ⚜
Information provided with us :
Diameter of the given circle is 14 cm.What we have to calculate :
Area of that circle?Performing Calculations :
Here we would be first calculating the radius of the given circle. As we know that radius of the circle is calculated by the formula,
r = d / 2Putting the values,
=> r = 14 / 2
=> r = 7
Therefore, radius is of 7 cm.
Now, heading up to calculate the area of circle.
Formula,
A = πr²Putting the values in the formula,
=> A = 22/7 (7)²
=> A = (22/7) × 7 × 7
=> A = 22 × 7 × 7 / 7
=> A = 22 × 49 / 7
=> A = 22 × 7
=> A = 154 cm²

One year, the population of a city was 201,000. Several years later it was 237,180. Find the percent increase.
Answer:
18%
Step-by-step explanation:
% increase = new population - old population x 100
old population. 1
% increase = 237180 - 201000 x 100
