Nikita ran a 5-kilometer race in 39 minutes (0.65 of an hour) without training beforehand. In the first part of the race, her average speed was 8.75 kilometers per hour. For the second part of the race, she started to get tired, so her average speed dropped to 6 kilometers per hour. Which expression represents Nikita’s distance for the second part of the race?

What is x if n≠m? Please help!
Answer: [tex]x = \frac{mn(q - p)}{n-m}\\\\[/tex]
================================================
Work Shown:
Part 1
[tex]\frac{x-m}{m} + p = \frac{x-n}{n} + q\\\\\frac{x-m}{m} - \frac{x-n}{n} = q - p\\\\\frac{n(x-m)}{mn} - \frac{m(x-n)}{mn} = q - p\\\\\frac{xn-mn}{mn} - \frac{xm-mn}{mn} = q - p\\\\\frac{xn-mn-(xm-mn)}{mn} = q - p\\\\[/tex]
Part 2
[tex]\frac{xn-mn-xm+mn}{mn} = q - p\\\\\frac{xn-xm}{mn} = q - p\\\\\frac{x(n-m)}{mn} = q - p\\\\x(n-m) = mn(q - p)\\\\x = \frac{mn(q - p)}{n-m} \\\\[/tex]
-------------------------------
Explanations:
There are quite a bit of steps. I decided to break things into two parts.The goal is to get x all by itself on its own side, which is why I subtracted (x-n)/n from both sides in part 1, step 2. I also subtracted p from both sides.Afterward, I gave each fraction the LCD mn. I multiplied top and bottom of the first fraction by n/n. I did a similar operation to the second fraction, but with m instead.From there, we distribute and simplify. The mn terms cancel on the left side numerator (second step of part 2).The n≠m is there to prevent the denominator (n-m) from being zero. We cannot divide by zero. If the formulas don't properly display, then you might have to refresh the page.PLZ HELP I NEED THIS ANSWER :'(

if the base area of a cylinder is 15.6 square centimeters and the height is four centimeters what is the volume of the cylinder?
Answer:
Volume of the cylinder = 62.4 cm³
Step-by-step explanation:
Volume of a cylinder = area of base × height of the cylinder
Area of base = 15.6 square centimeters
Height of the cylinder = 4 centimeters
Volume of a cylinder = area of base × height of the cylinder
= 15.6 cm² × 4 cm
= 62.4 cm³
Volume of the cylinder = 62.4 cm³

Answer and Step-by-step explanation:
First, look at the inequality. We see the there is a greater than or equal to sign.
That means the graphs can NOT be C or D, since those graphs only apply to inequalities with the greater than or less than sign.
That leaves us with graphs A and B.
We see the y is greater than the value, so anything above the line is filled in.
That means that graph A is the answer. Which means,
Answer choice B, graph A.

Solve for x
Answer:
x = 5
Step-by-step explanation:
We are to solve for x
7 - 10/x = 2 + 15/x
We Multiply both sides by x
x(7 - 10/x) = x(2 + 15/x)
7x - 10 = 2x + 15
Collect like terms
7x - 2x = 15 + 10
5x = 25
x = 25/5
x = 5

Which number line represents the solution to 5x ≥ 30?
Answer:
Its B
Step-by-step explanation:
since the symbol has a line underneath its shaded so A & B are left.
the symbol shows > so the point is where the line goes, for this question it goes to the right.
The required number line represents the solution to 5x ≥ 30 is shown in option B.
What is a number line?A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
Here,
According to the question, the inequality 5x ≥ 30 can be solved by dividing both sides by 5, which gives x ≥ 6. This means that any number greater than or equal to 6 is a solution to the inequality.
Looking at the number line options, we can see that only the last one correctly represents the solution to the inequality. The line starts at 6 and includes all numbers greater than or equal to 6, which matches the solution x ≥ 6.
Therefore, the correct answer is the number line shown in option B.

please help me !:( it’s due at 8:30
Answer:
y=-4x+5
Step-by-step explanation:
Let us first find the slope.
Given the points, (0,5) and (1,1) The slope of the line is (5-1)/(0-1)=
4/-1=
-4
The line also intercects the y axis at (0,5) Therefore, the b intercept would be 5
The final equation would be,
y=-4x+5

Answer:
The intersection point is (-0.5, -1).
So the x-coordinate is -0.5.
Step-by-step explanation:
Using the elimination method:
2.4x - 1.5y = 0.3
1.6x + 0.5y = -1.3 Multiply this equation by 3:
4.8x + 1.5y = -3.9 Add this equation to the first one:
7.2x = -3.6 - note we eliminate the terms in y.
x = -3.6 / 7.2
x = -0.5.
Now plug this into the first equation:
2.4(-0.5) - 1.5y = 0.3
-1.5y = 0.3 + 2.4*0.5
-1.5y = 1.5
y = -1.

Lynn has a box of crayons.
4/9 of the crayons are blue
65% of the remaining crayons are red.
The other 14 crayons are yellow.
How many crayons are in the box altogether?
Answer:
There are 72 crayons in the box
Step-by-step explanation:
Fractions
To solve this problem we'll manage numbers as fractions to keep the precision up to the end of it.
Lynn has a box of crayons. It's given 4/9 of the crayons are blue. The remaining crayons are:
[tex]1-\frac{4}{9}=\frac{5}{9}[/tex]
From that portion, 65% are red, or equivalently, 35% are yellow.
We write 35% as a fraction:
[tex]\displaystyle 35\%=\frac{35}{100}=\frac{7}{20}[/tex]
Thus, the portion of yellow crayons is:
[tex]\displaystyle \frac{7}{20}\cdot \frac{5}{9}=\frac{7}{36}[/tex]
This fraction of x crayons is equal to 14, thus:
[tex]\displaystyle x=\frac{14}{\frac{7}{36}}=14\cdot\frac{36}{7}[/tex]
x = 72
There are 72 crayons in the box

Step-by-step explanation:
As x goes up by 1, f(x) goes up by 2. The next line of the chart would be ...
x = 4+1 = 5; f(x) = 9+2 = 11
The appropriate choice is f(5) = 11.
