Answer:
C. 15
Step-by-step explanation:
1. First, let's solve the system of equations; [tex]-m - n = 5, m - n = -3[/tex]
Solve -m - n = 5 for m.
[tex]-m -n = 5[/tex] [tex]-m-n+n=5+n[/tex] [tex]-m = n + 5[/tex] [tex]\frac{-m}{-1} = \frac{n+5}{-1}[/tex] [tex]m = -n - 5[/tex]Substitute -n - 5 for m in m - n = -3.
[tex]m - n = -3[/tex] [tex]-n - 5 - n = -3[/tex] [tex]-2n-5=-3[/tex] [tex]-2n-5+5=-3+5[/tex] [tex]-2n = 2[/tex] [tex]\frac{-2n}{-2} = \frac{2}{-2}[/tex] [tex]n = -1[/tex]Substitute -1 for n in m = -n - 5.
[tex]m = -n - 5[/tex] [tex]m = -(-1) - 5[/tex] [tex]m = 1 - 5[/tex] [tex]m = -4[/tex]2. Okay, now that we know m = -4 and n = -1, let's solve for m^2 -n^2.
[tex]m^2-n^2[/tex] [tex](-4)^2-(-1)^2[/tex] [tex]16 - (-1)^2[/tex] [tex]16 - 1[/tex] [tex]15[/tex]Therefore, the answer is C. 15!
Answer:
c 15
Step-by-step explanation:
-m-n=5
m+n=-5
(m+n)×(m-n)=m²-n²
m²-n²=-3×-5=15

Rachel can finish the job in 5 hours, while Carl can finish the same job in 8 hours. How long will it take them to finish the job together?PLS ANSWER ASAP WILL MARK BRAINLIEST IF CORRECT!!!!
5-7 hours i think, not 100% sure
Step-by-step explanation:
if you have any answer choices can you please list them? I'm not sure if this is correct but I'm guessing it'll take them both 5ish hours. Since Rachel can finish it in 5 hours but Carl takes longer, either they'll get it done in 5 hours or may it'll take a longer like 6 hours if Carl slows Rachel down. hope this helps!

please help me solve x please
Answer:
x = 5
Step-by-step explanation:
The exterior angle theorem states that the measure of each exterior angle of a triangle is equal to the sum of the opposite and non-adjacent interior angles.
In the given problem, the exterior angle is < B, and the non-adjacent interior angles are < D and < C.
Given that:
< B = 12x + 8
< D = 8x + 8
< C = 20°
Set up the following formula to solve for x:
(8x + 8) + 20 = 12x + 8
Combine like terms:
8x + 28 = 12x + 8
Subtract 8 from both sides:
8x + 28 - 8 = 12x + 8 - 8
8x + 20 = 12x
Subtract 8x from both sides:
8x - 8x + 20 = 12x - 8x
20 = 4x
Divide both sides by 4 to solve for x:
20/4 = 4x/4
5 = x
Therefore, x = 5.

The trout swam 8,000centimeters directly upstream at a constant velocity. It swam that distance in 0.8minutes. What was the trout's velocity?
Write your answer as a whole number.
centimeters per minute upstream
Answer:
It would approximately be 3.73 m/h
Step-by-step explanation:
0.8 mins is 48 seconds
I then divided 8000 by 48 seconds to see how many cm it traveled per second.
It traveled 166.666666667 cm per second
I then converted cm to feet
so it was 5.468066491699474 feet per second
I then converted feet to miles, so it was 0.0010356186537309611598 miles per second.
Then I multiplied it by 60 so it was 0.06213711922 miles per minute.
Finally I multiplied it by 60 again to make it 3.72822715343 miles per hour.
I rounded it to the nearest hundredth making it 3.73 m/h
Amtrak: 80 miles in 5 hours

Hello, There! I'll be Glad to help
QuestionAmtrak: 80 miles in 5 hours
Metra: 30 miles in 2 hours
Which train is faster? How do you know?
Answer[tex]\textbf{Amtrak is correct}[/tex]
Step-by-step explanation:
So First we have to figure out Has fast the trains go in 1 hour so we are going to divide...
Metra30 ÷ 2 = 15 Miles (Metra can go 15 Miles in one hour)
Amtrak80 ÷ by 5 = 16 (Amtrak Can go 16 Miles in one hour)
_______________________________________
So If Metra Were to keep going Here are the list of Miles Below
(45 Miles in 3 hours)
(60 Miles in 4 hours)
(75 miles in 5 hours)
________________________________________
Amtrak
(96 Miles in 6 hours)
(112 miles in 7 hours )
(128 miles in 8 hours)
Therefore, Amtrak is the Fastest Train

centered at the origin?
The image of the point (8, 6) dilated by a scale factor 1/2 is (4, 3)
The given point is (8, 6)
The scale factor of dilation = 1/2
To dilate a given point (x, y) by a scale factor m, multiply each of the coordinates (x, y) by m
The image = (mx, my)
For the point (8, 6) dilated by 1/2, the image will be calculated as shown below:
[tex](\frac{1}{2}\times 8, \frac{1}{2} \times 6)\\= (4, 3)[/tex]
The image of the point (8, 6) dilated by a scale factor 1/2 is (4, 3)

Jane invests £300 at a simple interest rate of 4.5% per year. At the end of each year, Jane gives the interest to a charity Work out the least number of years it will take for the total amount given to the charity to be greater than £50. Show your workings.
Answer:
At least 4 years
Step-by-step explanation:
Simple interest is given by
I = Prt
so here, one year's interest is
I = 300(.045) = 13.5
Divide 50 by 13.5 and get 3.7 years...thus
she will need four years to donate 50...
Step-by-step explanation:
Interest Rate = (Simple Interest × 100)/(Principal × Time).
given
Principal(P) = 300
Interest Rate(I.R) = 4.5%
Simple Interest(S.I) = 50
required
Time(T)
I.R = (S.I × 100)
(P ×T)
T × I.R = (S.I × 100) ×T
I.R (P × T) × I.R
T = (S.I × 100)
(P × I.R)
= (50 × 100)
(300 × 4.5)
= 5000
