she walked 1 3/8 miles more than she ran, Hope this helps :D
Answer:
1) 6r+7=13+7r —> 7r–6r=7–13 —> r = – 6
2) 13–4x=1–x —> 4x–x=13–1 —> 3x=12 —> x=12/3 —> x=4
3)–7x–3x+2=–8x–8 —> –8x+7x+3x=2+8 —> 2x=10 –> x= 10/2 –> x= 5
4)–8–x=x–4x —> –x–x+4x=8 —> 2X=8 —> x= 8/2 —> x= 4
5) –14+6b+7-2b=1+5b —> 5b +2b –6b = –14+7–1 —> b=–8
6) n+2=–14–n —> n+n=–14–2 —> 2n = –16 —> n = – 16/ 2 —> n = – 8
7) n – 3n = 14 –4n —> n –3n + 4n = 14 —> 2n = 14 —> n = 14/ 2 —> n = 7
8) 7a – 3 = 3 + 6a —> 7a – 6a = 3 + 3 —> a = 6
9) 3(1–3x ) =2(–4x+7) —> 3 –9x = –8x+14 —> 9x–8x = 3–14 —> x = –11
10) –10 +x+4–5 =7x –5 —> 7x–x = –10+4–5 +5 —> 6x = –6 —> x= –6/6 —> x = –1
11) –8n +4(1+5n)=–6n–14 —> –8n +4 + 20n = – 6n– 14
20n –8n +6n= –14 –4 —> 18n = – 18 —> n = –18/18 —> n = –1
12) –6n–20=–2n +4(1–3n) —> –6n –20 = – 2n +4 –12n —> 12n +2n –6n = 4 +20 —> 8n =24 —> n = 24/8 —> n =3
I hope I helped you^_^
We know that
P = A/D
Where,
P = monthly payments,
A = Total amount =$1,000,000
![D=[(1+r/12) ^{12*t}-1]/[(r/12)*(1+r/12)^{12*t}]](https://tex.z-dn.net/?f=D%3D%5B%281%2Br%2F12%29%20%5E%7B12%2At%7D-1%5D%2F%5B%28r%2F12%29%2A%281%2Br%2F12%29%5E%7B12%2At%7D%5D%20%20)
in this problem
t=30 years
r=8%----> 0.08
![D=[(1+0.08/12) ^{12*30}-1]/[(0.08/12)*(1+0.08/12)^{12*30}] =136.2835](https://tex.z-dn.net/?f=D%3D%5B%281%2B0.08%2F12%29%20%5E%7B12%2A30%7D-1%5D%2F%5B%280.08%2F12%29%2A%281%2B0.08%2F12%29%5E%7B12%2A30%7D%5D%20%3D136.2835)
the answer is$7337.65
A perfect square is a number that can be expressed as the product of two equal integers.
Ok...I considered it....oh..u want me to answer it...lol..ok
5/6(1/2x + 6) - 3x
5/12x + 30/6 - 3x
5/12x - 36/12x + 5
- 31/12x + 5 <===
