Answer:
n = 4
im not good at explaining by text but i hope this helps
Step-by-step explanation:
3n - 8 = 4
you want the variable by itself so you will start with the number without the variable
3n - 8 = 4
next to the 8 is a - sign so it will is negative now it has to be the opposite
3n - 8 = 4
+8. +8
you cancel out the 8 and 4+8 is 12
now you have to do 12 ÷ 3 to get the variable by itself
12 ÷3 is 4

Josh ran 84.6 miles in June. In July he ran 0.55 times this distance due to an injury. How many more miles did he run in June than in July?
I did 0.80-0.25=0.55
so I figured that is what she had left so I know took the total 0.80-0.55 and got0.25 which is B.
My friend said the correct answer was A.
Don't worry I just did this problem!
The distance Josh ran more in June than in July, if Josh ran 84.6 miles in June. In July, he ran 0.55 times this distance in June, is 38.07 miles.
What is distance?The complete movement of an object, regardless of direction, is referred to as distance. The amount of ground a thing travels from its starting point to its destination is also referred to as distance.
Given:
Josh ran 84.6 miles in June. In July, he ran 0.55 times this distance in June,
Calculate the distance covered in July = 0.55 × 84.6
Calculate the distance covered in July = 46.53 miles
Calculate the distance he ran more in June than in July = 84.6 - 46.53
The distance he ran more in June than in July = 38.07 miles

PLEASE HELP ME ASAP(WORTH 30 POINTS). If the domain is {0, 2, -6}, what is the range of y = -2x + 3?
Answer:
Range = {3, -1, 15}
Step-by-step explanation:
Domain = {0,2,-6}
function : y= -2x + 3
We replace the value of x with domain,
when x = 0
y = -2 × 0 + 3
y = 3
When x = 2
y = -2 × 2 + 3
y = -1
When x = -6
y = -2 × -6 + 3
y= 12 + 3
y = 15

What is the opposite and the absolute value of 3?
The opposite of 3 is 3. The absolute value of 3 is 3.
The opposite of 3 is -3. The absolute value of 3 is 3.
The opposite of 3 is 3. The absolute value of 3 is -3.
The opposite of 3 is -3. The absolute value of 3 is -3.
Answer:
Option D) The opposite of 3 is -3. The absolute value of 3 is -3.
Step-by-step explanation:
On a number line, if you go three to the right from 0, you get 3. But if you go the same amount to the left of 0, you would get -3. I can't think of any other way to explain the opposite. The absolute value is usually the same number but the absolute value is usually the same number, but it's opposite.

Mia bought 2 adult tickets and 4 kid's tickets. Each adult ticket cost $13.50 and each kid ticket cost $10.25. How much did Mia spend on tickets

Solving for the first part, you get 27 for adult tickets and 41 for the children tickets. When you add the two values, you get 68.
A quarter cone has a diameter of 16 and a height of 10. What is the approximate volume of the quarter cone? Round to the nearest tenth where necessary.
Answer:
167.6 units^3
Step-by-step explanation:
Find the volume of the entire cone, and then divide the result by 4 to obtain the volume of the quarter cone:
Formula for the volume of a cone is V = (1/3)(base area)(height)
In this case the volume of the entire cone is V = (1/3)(pi)(8)^2*(10), or
670.21.
Taking 1/4 of this, we get the volume of the quarter cone:
670.21/4 = 167.6 units^3

What are the solution(s) to the quadratic equation 40 - x2 = 0?
x = +2/10
x = +4/10
O x= +2/5
x = +4,5
Answer:
±2√10
Step-by-step explanation:
Given the equation 40 - x^2 = 0
Add x^2 to both sides
40 - x^2 + x^2 = 0+ x^2
40 = x^2
x^2 = 40
x = ±√40
x = ±√4 * √10
x = ±2√10
Hence the value of x is ±2√10

Solve by taking square roots x 2 - 2 = 79
Answer:
9
Step-by-step explanation:
x^2 - 2 = 79
The first step is to get rid of the 2 on the left side. You do this by adding two on both sides. You should then get x^2 = 81.
Now, you have the just take the square root of 81, which is 9.
if i got shorts for 30 dollars and the original price was 40 what was the discount
Answer:
25%
Step-by-step explanation:
30/40 = 0.75 = 75% paid
100-75 = 25% discount
Answer:
[tex]25\%[/tex]
Step-by-step explanation:
To find the discount of an object, one must set up the equation, the difference between the original and the paid price, over the original price, equals percent over 100. In essence;
[tex]\frac{(original-paid)}{original}=\frac{percent}{100}[/tex]
Substitute in the given values;
[tex]\frac{(40)-(30)}{40}=\frac{percnet}{100}[/tex]
Solve;
[tex]\frac{10}{40}=\frac{percent}{100}[/tex]
Simplify,
[tex]\frac{1}{4}=\frac{percent}{100}[/tex]
Cross products,
[tex]100 = 4(percent)[/tex]
Inverse operations,
[tex]100=4(percent)\\/4\\\\25 = percent[/tex]
please help i really need it
Answer:
D
Step-by-step explanation:
This equation is in factored form. Meaning you can find the x intercepts of the graph from it. All you need to do is find reverse the numbers inside the parentese. So if its negative, make it positive, if its positive, make it negative. By doing this, you should find that the x-intercepts of this graph are 2 and 3 and the donly graph with x-intercepts at these places is graph d.

Aidan took a 1020 km trip, travelling by Bus and By Train. The bus travelled at 105 km/h, and the train travelled at 160 km/h. The whole trip took 8 Hours. How Far did he travel on the train? Solve algebraically, and round your final answer to one decimal place.
Answer:
523.6 km
Step-by-step explanation:
Let x represent the distance traveled by train. Then 1020-x is the distance traveled by bus. The travel times are given by the relation ...
time = distance/speed
Then the total travel time in hours is ...
x/160 +(1020-x)/105 = 8
21x +32640 -32x = 26880 . . . . . multiply by 3360
5760 = 11x . . . . . . . . . add 11x -26880
523.6 ≈ x . . . . . . . . . . divide by 11
Aidan traveled about 523.6 km by train.
