Step-by-step explanation:
x=35÷2.5 will devide 35 by 2.5 to get x
Answer: x = 14
Step-by-step explanation: To find the value of x, you can simply divide 35 by 2.5, which gives you a final result of 14. Therefore, x = 14.

Wilma can mow the lawn in 4 hours. If Kyle helps her with another mower, the lawn can be mowed in 3 hours. How many hours would it take Kyle if he worked alone?
Answers
Answer:
12 hours
Step-by-step explanation:
Let w = Wilma alone
Let k = Kyle alone
Let t = Working together
Given the following data;
Time it took Wilma = 4 hours
Time it took them together = 3 hours
Time it took Kyle = x
To find the time it will take Kyle, we would use this arithmetical expression;
[tex] \frac {1}{w} + \frac {1}{k} = \frac {1}{t}[/tex]
Substituting into the equation, we have;
[tex] \frac {1}{4} + \frac {1}{x} = \frac {1}{3}[/tex]
Lowest common denominator (LCD) = 12x
Multiplying all through by "12x" we have;
[tex] 12x * \frac {1}{4} + 12x * \frac {1}{x} = 12x * \frac {1}{3}[/tex]
Simplifying the equation, we have;
[tex] 3x + 12 = 4x[/tex]
Rearranging the equation, we have;
[tex] 4x - 3x = 12[/tex]
x = 12 hours.
Therefore, it would take Kyle 12 hours to mow if he worked alone.

Step-by-step explanation:
Determine whether f(x) = 4x^2 – 16x + 6 has a maximum or a minimum value and find that value.
a
maximum; –10
b
minimum; –10
c
maximum; 2
d
minimum; 2
Answers
Answer:
minium:-2................
The function f(x) = 4x² – 16x + 6 has a minimum value is –10 when the value of x is 2. Then the correct option is B.
What is differentiation?
The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decreasing.
The function is given below.
[tex]f(x) = 4x^2 -16x + 6[/tex]
Differentiate the function, then we have
[tex]\dfrac{d }{dx} f(x) =\dfrac{d}{dx}(4x^2 -16x + 6) \\\\ \dfrac{d }{dx} f(x) =8x - 16 \\[/tex]
The value of x will be
[tex]8x - 16 = 0\\x = 2[/tex]
Then again differentiate the function, if the value comes negative then maxima and if the value is positive then minima.
[tex]f''(x) = \dfrac{d }{dx} f'(x) \\\\f''(x)=8x - 16 \\\\f''(x) = 8\\\\ f''(x) > 0[/tex]
Then the function is minimum at 2.
More about the differentiation link is given below.
