Answer:
u = t/18 - 5
Step-by-step explanation:
45n + 18u = t where t is the total price, n is the number of new video games, and u is the number of used video games
plug in two:
90 + 18u = t
solve in terms of u:
18u = t - 90
u = t/18 - 5

three times a number decreased by 11 3n - 11
Is the statement true or false? If false, give a counterexample.
For all real numbers a, b and c, a(b + c) = ab + bc.
A. true
B. false; a(b + c) = ab − ac
C. false; if a = b = c = 1, then 1(1 + 1) ≠ 1(1) + 1(1)
D. false; if a = 1, b = 2, and c = 3, then 1(2 + 3) ≠ 1(2) + 2(3)
Answer:
D. false; if a = 1, b = 2, and c = 3, then 1(2 + 3) ≠ 1(2) + 2(3)
Step-by-step explanation:
A is false, because the a is being distributed/ being multiplied to all terms inside the parenthesis, and not the term b.
B is also false. There is no indicated negative signs.
C is also false because 1(1 + 1) is EQUAL to 1(1) + 1(1)
D is true.
Emma biked 15 miles. One mile is approximately equal to 0.6 kilometers. What is the number of kilometers Emma biked?
Answer:
About 9 kilometers
Step-by-step explanation:
15x.6= 9
Answer: x = 9
Step-by-step explanation:
I’ll use x as the number of kilometers Emma bikes
1/0.6 = 15/x - set up proportion
1x = 9 cross products
x = 9 - divide both sides by 1 and you get 9

The speed of a body falling freely from rest in a vacuum varies directly with the length of the time it falls. If after 6 seconds, a body was falling 58.8 m/s, how fast was it falling 4 seconds later? (Round off your answer to the nearest meter per second.)
Answer:
The body is falling at 98 m/s after 4 seconds later.
Step-by-step explanation:
The magnitude of the speed of a body dropped from rest is:
[tex] v = gt [/tex]
So, if the speed of a body dropped after 6 seconds is 58.8 m/s, after 4 seconds later is:
[tex] v = gt = 9.81 m/s^{2}*(4s + 6s) = 98.1 m/s = 98 m/s [/tex]
Hence, the body is falling at 98 m/s after 4 seconds later.

When the full season tickets first went on sale,2,000 Full season tickets sold for Section N. Two weeks after the tickets first went on sale, another 1,500 full season tickets were sold for section N. How much money spent on full season tickets for section N in total? How much more money was spent when the tickets first went on sale than after the first two weeks.
Image showing the arena ticket prices is missing, so i have attached it.
Answer:
$10000 more money was spent when the tickets first went on sale than after the first 2 weeks
Step-by-step explanation:
We are told that when the full season tickets first went on sale, that 2000 full season tickets were sold for section N.
Now, from the area ticket prices table attached, we can see that full season tickets for Section N costs $20
Thus, amount of money spent when the tickets first went on sale = 2000 × 20 = $40000
We are told that 2 weeks after the tickets first went on sale, they sold 1500 tickets. Thus, amount spent after 2 weeks release = 1500 × 20 = $30000
Difference in amount spent at the beginning and after 2 weeks = $40000 - $30000 = $10000
Thus, $10000 more money was spent when the tickets first went on sale than after the first 2 weeks

Does (12+6)÷2 and 12+6÷2 have the same answer
Answer:
No
Step-by-step explanation:
If you go by PEMDAS then you would do whatever is in the parenthesis first, which in this case would be 12 + 6. And then you would divide, so 12 + 6 = 18/2 = 9. In the other equation you would do division first, so that would be 6/2 which equals 3 and then you would add that to 12 which equals 15.
Answer:
No, because it has parentheses. You have to do the parentheses first (cause of order of operations) and the divide, (or based on whatever your step is from order of operations) which your going to get a diff answer.

(a) On the grid above, draw the line x = 3
The Graph will look like this:
The graph will show a vertical line crossing the x-axis at x = 3 and extending infinitely in both the positive and negative y-directions.
The equation x = 3 represents a vertical line that passes through the point (3, 0) on the Cartesian coordinate system. This means that for every value of y, the corresponding x-coordinate is always 3. Since the line is vertical, it extends infinitely in both the positive and negative y-directions.
To visualize the line x = 3 on a graph:
1. Draw two perpendicular axes, the horizontal x-axis, and the vertical y-axis.
2. Since x = 3, draw a vertical line passing through the point where x = 3 on the x-axis (at x = 3) and extending through the entire y-axis.
The resulting graph will show a vertical line crossing the x-axis at x = 3 and extending infinitely in both the positive and negative y-directions.

Two skaters are practicing at the same time on the same rink. A coordinate grid is superimposed on the ice. One skater follows the path y = −2x + 32, while the other skater follows the curve y = −2x2 + 18x. Find all points where they might collide if they are not careful.
Answer:
The skaters will collide at the points;
(2,28) and (4,24)
Step-by-step explanation:
The points they might collide will be the points when both y are equal;
-2x + 32 = -2x^2 + 18x
2x^2 -18x -2x + 32 = 0
2x^2 -20x + 32 = 0
2x^2 - 16x - 4x + 32 = 0
2x(x -8) -4( x -8) = 0
(2x -4)(x -8) = 0
2x = 4 or x = 8
x = 4/2 or x = 8
hence; x = 2 or 8
Now let’s get the y value
at x = 2, just substitute into any of the 2
y = -2x + 32
y = -2(2) + 32
y = -4 + 32 = 28
at x = 4
y = -2(4) + 32
y = -8 + 32
y = 24
The points that they will collide are;
(2,28) and (4,24)
Answer:
They will collide at (2,28),(8,16)

The delivery truck total drives 37 miles on those three routes.
What is a fraction?A fraction describes how much part is there to the total part.
According to the given question, a delivery truck drives three routes in one day.
The first route is [tex]12\frac{2}{3}[/tex] miles long, the second route is [tex]10\frac{3}{4}[/tex] miles long and the third route is [tex]15\frac{1}{2}[/tex] meters long.
To find the total number of miles the delivery truck drives we have to add the distances of all three routes which are in fractions which is,
= [tex]( 12\frac{2}{3} + 10\frac{3}{4} + 15\frac{1}{2} ) miles.[/tex]
= [tex]\frac{37}{3} + \frac{43}{3} + \frac{31}{3} miles.[/tex]

If the question is how many variable terms are in 3x^3y + 5x7 - 4y + x-z+9 the answer would be 7 because each of the variables are separated by the + and - signs and if you count them like that right now you would get 5 and if you add the 3 from the beginning you would get 7 saying that the variable terms are represented by the letters am I correct.
Given:
The expression is
[tex]3x^3y+5x^7-4y+x-z+9[/tex]
To find:
The number of variable terms.
Solution:
Constant values, variables, product of constants and variables are known as terms if they are separated by "+" sign.
The terms which contain atleast one variable is called variable terms.
We have,
[tex]3x^3y+5x^7-4y+x-z+9[/tex]
Here, the terms are [tex]3x^3y,5x^7,-4y,x,-z[/tex] and 9.
All terms contain variables except 9 which is a constant.
Therefore, the number of variable terms is 5.

Give your answer rounded to 1 DP.
Answer:
110.9 cm²
Step-by-step explanation:
The area (A) of an equilateral triangle is calculated as
A = [tex]\frac{s^2\sqrt{3} }{4}[/tex] ( s is the side length )
Here s = 16, thus
A = [tex]\frac{16^2\sqrt{3} }{4}[/tex]
