Since you can earn 28 dollars by washing 7 cars, and you want to find the amount money you can make by washing 6 cars.
[tex]\frac{28}{7} = \frac{x}{6}[/tex]
First, you should find the amount of money you can make by washing 1 car (unit rate).
[tex]\frac{28}{7} = \frac{x}{1}[/tex]
To get from 7 to 1, you have to divide 7 by 7; 7 ÷ 7 = 1.
Do the same thing to the numerator; 28 ÷ 7 = 4.
Now you know how much you make by washing 1 car, you need to find how much you make by washing 6 cars.
[tex]\frac{4}{1} = \frac{x}{6}[/tex]
To get from 1 to 6, you multiply by 6. 1 times 6 equals 6.
Now do the same thing to the numerator; 4 × 6 = 24.
You can earn 24 dollars by washing 6 cars.

Which of the following depicts a graph of a polynomial with a negative leading coefficient?
Answer:
Graph D.
Step-by-step explanation:
Hey there!
A coefficient is the number being multiplied by the variable,
Example: 5x - 5 is a coefficient
Graph d has a negative slope meaning the slope would be,
-1, -2, -3, -4, -5, ect.
So graph D is correct.

how long will an object take to travel 4.8km at 48m/s?
Answer:
what is your fav movie or show on netfix
Step-by-step explanation:
Answer:
[tex] \boxed{\sf Time \ taken \ (t) = 100 \ s} [/tex]
Given:
Distance (d) = 48 km = 4800 m/s
Speed (s) = 48 m/s
To Find:
Time taken (t)
Step-by-step explanation:
Formula:
[tex]\boxed{ \bold{ Speed \ (s) = \frac{Distance \ (d)}{Time \ (t)}}}[/tex]
Substituting value of s & d in the equation:
[tex] \sf \implies 48 = \frac{4800}{t} \\ \\ \sf \implies t = \frac{4800}{48} \\ \\ \sf \implies t = 100 \: s[/tex]
[tex] \therefore[/tex]
Time taken (t) = 100 s

2. Use the ideas in drawings (a) and (b) to find the solution to
Gauss's Problem for the sum 1 + 2 + 3 + ... + n. Explain
your reasoning.
Answer:
Step-by-step explanation:
Hello, I will compute twice the sum so I need to compute,
[tex]\begin{aligned}1&+2&+...+&(n-1)&+n\\\\n&+(n-1)&+...+&2&+1\\\\-&-----&---&---&---\\\\(n+1)&+(n+1)&+...+&(n+1)&+(n+1)\end{aligned}[/tex]
1+n = n+1
2 + n-1=n+1
...
n-1+2=n+1
n+1=n+1
So, this is n times n+1 so it is n*(n+1)
[tex]2(1+2+3...+n)=n(n+1)\\\\1+2+3...+n=\dfrac{n(n+1)}{2}[/tex]
if john gets 1 apple and already has 20 in a basket how many do you have in total.
Answer:
21
Step-by-step explanation:
the reason it is 21 is because u have 20 then u add 1 so it is 21 20+1=21
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
John already has 20 apples. If John gets 1 more apple, he would have 21 apples in total.
The word gets means addition. 20 plus 1 equals 21.
John has 21 apples after he gets another apple.
Ok technically I would have 0 apples since I didn't receive any only John did.

Question:
Five times the sum of a number and 27 is greater than or equal to six times the sum of that number and 26.
What is the solution set of this problem?
Answer:
[tex]x \leq -21[/tex]
Step-by-step explanation:
Given
Represent the number with x
So:
[tex]5 * (x + 27) \geq 6 * (x + 26)[/tex]
Required
Determine the solution set
[tex]5 * (x + 27) \geq 6 * (x + 26)[/tex]
Open Both Brackets
[tex]5 * x + 5 * 27 \geq 6 *x + 6 * 26[/tex]
[tex]5x + 135 \geq 6x + 156[/tex]
Collect Like Terms
[tex]5x - 6x \geq 156-135[/tex]
[tex]- x \geq 21[/tex]
Multiply both sides by -1
[tex]x \leq -21[/tex]
Hence, the solution set is [tex]x \leq -21[/tex]

Samantha conjectures that for x < -1, it is true that x5 - 2 > x. Is her conjecture correct? Why or why not?
Answer:
The conjecture cannot work for any negative numbers, It works for x > 1.3.
Step-by-step explanation:
An odd power preserves the sign. For |x| > 1, the power increases the magnitude. For x < 0, adding -2 only increases the magnitude more. A negative number of larger magnitude will not be "greater than" the reference. It will be "less than."
It only takes a counterexample to show the conjecture is incorrect.

What do Steven Hawking and Thomas Edison have in common
- Both men made mathematics discoveries
- Both men made discoveries that were well-received
- both men created technological inventions
- Both men used observations in their field of study
Answer:
- Both men made discoveries that were well-received
Step-by-step explanation:
Stephen Hawking and Thomas Edison were two great physicist or scientists, whose discoveries were well-recieved by all over the world.
Stephen Hawking gave theories in cosmology such as black holes that includes the second law, that states that black hole will never reduce its shape.
Thomas Edison was one of the great inventors in the history in different feilds such as mass communication, electric power generation, motion pictures, and sound recording. some of the inventions include Automatic Telegraph and tin foil phonograph.
They both have given scientific research and logics for their discoveries and so people accepted them.
Hence, the correct answer is " Both men made discoveries that were well-received ".
The answer is:

Distance Traveled and Gas Left in Tank Distance Traveled (in miles) 0 90 180 270 Amount of Gas Left in Tank (in gallons) 15 12 9 6 How many gallons of gasoline does the car have left after it has traveled 330 miles?
Answer:
4 gallons of gasoline the car has left after it has traveled 330 miles.
Step-by-step explanation:
We are given with the following data of Distance Traveled and Gas Left in Tank below;
Distance Traveled (in miles) Amount of Gas Left in Tank (in gallons)
0 15
90 12
180 9
270 6
330 ?
As we can see from the table that for every 90 miles of distance traveled, there has been a reduction of 3 gallons of gas which is left in the tank, i.e;
From 90 to 180 - Gas reduced from 12 to 9
This means that in 1 gallon of gas, the distance traveled is = [tex]\frac{90}{3}[/tex] = 30 miles
So, from distance 270 to 300, the amount of Gas Left in Tank = 6 - 1 = 5 gallons
From distance 300 to 330 miles, the amount of Gas Left in Tank = 5 - 1 = 4 gallons
Hence, 4 gallons of gasoline is left after the car has traveled 330 miles.
Find the point P that partitions the line segment AB given the ratio.
A (3, 6) B(4, 3) with the ratio 2:1
(11 over 3,4)
(4,11 over 3)
(5, 8)
(10, 12 over 5)
Answer:
(11/3, 4)
Step-by-step explanation:
To calculate the coordinates of the point that partitions the line segment in the given ratio, we shall be using the internal division formula.
Mathematically, that is ;
= {(mx2 + nx1/(m+n), (my2 + ny1)/(m + n)}
m and n represents the ratios 1:2
(x1, y1) represents the coordinates of A
(x2,y2) represents the coordinates of B
From the question, let’s list out the individual values;
m = 2
n = 1
x1 = 3
x2 = 4
y1 = 6
y2 = 3
Substituting these values in the equation, we have;
(2(4) + 1(3)/(1+2) , (2(3) + 1(6)/(1 + 2))
= (8 + 3)/3 , (6 + 6)/3)
= (11/3, 12/3)
= (11/3 , 4)
