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
Miguel runs 5 miles in 38 minutes. At the same rate, how many miles would he run in 57 minutes?

Find mJTS
A) 104°
C) 120°
E) 87°
B) 128°
D) 74°
Answer:
104
Step-by-step explanation:
∠JTS = ∠SRT + ∠TSR {exterior angles equals sum of opposite interiror angles}
27x - 4 = 18x + 2 + 30
27x - 4 = 18x + 32
Add 4 to both sides
27x = 18x + 32 + 4
27x = 18x + 36
Subtract 18x from both sides
27x - 18x = 36
9x = 36
Divide both sides by 9
x = 36/9
x = 4
∠JTS = 27x - 4
= 27*4 - 4
= 108 - 4
= 104

The diagram shows a circle inside a square 16cm Work out the area of the circle
Answer:
Step-by-step explanation:
Since one side of the square is 16 cm, the diameter of the circle is also 16 cm. Which means that the radius is 8. the area of a circle is pi times radius square. so it is pi times 8 squared, which is 64pi
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!

Answer:
[tex]x>-5[/tex]
Step-by-step explanation:
[tex]\frac{-1}{5} x+1<2[/tex]
Subtract 1 from both sides
[tex]\frac{-1}{5} x+1-1<2-1[/tex]
Simplify
[tex]\frac{-1}{5} x<1[/tex]
Multiply both sides by -1, which reverses the inequality also
[tex]\frac{-1}{5} x(-1)>1(-1)[/tex]
Simplify
[tex]\frac{1}{5} x>-1[/tex]
Multiply both sides by 5
[tex]5*\frac{1}{5} x>5(-1)[/tex]
Simplify
[tex]x>-5[/tex]
Shelby invests £14000 in a savings account. The account pays 2.5% compound interest per year.
Work out the value of her investment after 2 years.
Answer:
70000
Step-by-step explanation:
Answer:
£14708.75
Step-by-step explanation:
Always start with the original amount, in this case 14000.
Then, because it's an increase, add 2.5 to 100. You could also think of it as adding 2.5% to 100%, which is 102.5%. We then divide that by 100.
So far our calculation is 14000 x 1.025.
We now need to do this for the two days on. We can do this in 2 ways.
1. 14000 x 1.025 x 1.025
or.
2. 14000 x 1.025^2
They're both the same thing.
We then type that calculation into your calculator and you should get £14708.75
Hope that helped :)
How do I solve this problem??
Answer:
32
Step-by-step explanation:
Because Triangle QPS has equal sides, it is an equilateral triangle. Which means its angles are 60°. 134-60 = 74. Because Lines QS and QR are equal angles QSR and QRS are the same. 180-74-74 = 32

Simplify ^75 select the correct answer
Answer:
to simplify the square root of 75, first I recognize that the perfect square 25 goes into it. So 75 = 25 x 3. Therefore the square root of 75 equals the square root of 25 times the square root of 3. And that means just 5 times the square root of 3.
Step-by-step explanation:
The square root of √75 is 5√3.
What is Radical?The √ symbol that is used to denote square root or nth roots. Radical Expression - A radical expression is an expression containing a square root.
A radical notation is an expression that incorporates a root, such as the square or cube root.
Given:
We have to find the square root of 75.
So, we have to factories 75 as
= 25 x 3
and, the square root of 25 is 5.
Then, √75 = √( 5 x 5 x 3)
= 5√3.

what is the slope intercept form of (1,6) and (-2,6)
Answer: y = 6
Step-by-step explanation:
This is still in slope intercept form but the only difference is that x equals 0.
If this confuses you, you can write
y = 0x+6 which would still be correct however, your teacher might prefer
y = 6 more.
