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.
*Tip: To divide whole numbers by decimals or decimals by decimals, then you’ll have to just divide regularly and align the decimal point where it originally was, as shown in the bracket where the dividend is.

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.
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.
