1. 4n + 5
2. 200
3. price of apples = 3, price of berries = 8, price of cherries = 5
4. x = 5, 13
5. 17/cos(50) = 26.447
6. x = -2
7. the "less 48" part is confusing to me, but assuming that [Jake] + [Jan] = 5[Jake] - 48, then Jake is 24 years old and Jan is 48 years old.
8.
x^3 + x^2 - 16x - 16 = 0
x^2(x + 1) - 16(x + 1) = 0
(x^2 - 16)(x+1) = 0
x = +/- 4, and -1
9. x = 24
10. x = 1, y = 2.5

 

Before a lot of people start posting, people should pm you the answers, because people could copy off other people. I pm'd you mine.

 

Hide from Pizza the Asian math wizard.

/hide

 

can I hide with you? ;9

1) 4n+5
2) 200
3) Apples: $3.00 Cherries: $5.00 Berries: $8.00
4) x=5, or x=13
5) 10.927 (it goes on so I rounded it to thousandths)
6) x= -2
7) Jake=24 years old, Jan=48 years old
8) x^3 + x^2 - 16x = 16
x^3 + x^2 - 16x - 16 = 0
x^3 + x^2 - 16(x+1) = 0
x^2(x+1) - 16(x+1) = 0
(x^2 - 16) (x+1) = 0
x= 4, -4 or -1
9) x=24
10) x=$1 y=$2.5

 

Just so people know, this ends tomorrow.

 

I would post, but i can see there are already several complete matching sets of answers posted.

 

Do not attempt to escape Pizza's mighty wrath

Anyway, I probably should have PM'd you the answers in the first place, Phil.

 

Not like i copied off you or anything

Also i notice that you changed number 5.

 

Haha yeah, I'm just saying that it probably would have been best to just PM him the answers to let everyone have an equal chance.

Also, I didn't change number 5..? Lmao

 

I think this is coming to an end and it's time for marking ^^

 

Pizza, I know you changed 4) your previous answer was -13, and -15 xD I marked them all as soon as they were posted and you had 9/10 ^^ You had #4 wrong xD

 

Ah I meant #4... whichever one the 5/13 one was

 

I only removed the negatives haha. They were still 5 and 13. I don't know why I typed them as negatives cause then the expressions wouldn't be rational.

But anyways, thanks~

 

1st Place Pizza
