Question

Answer 1

Answer 2

k

Answer 3

Alright so the first thing you'll want to do is write everything out thats given:
It said 19 lb was equal to iron, potassium, and mulch, so we can write that as:

19 = i + p + m

We also know that the supplement contains 16 times as much mulch as iron so we can write that as:
16m = i

We also know theres twice as much potassium as there is iron so we write that as:

2p = i

Answer 4

So now we need to solve for i for 16m = i and 2p = i

once you find what value i is for those two plug them back into 19 = i + m + p then try from there

Answer 5

so what should i do for step one

Answer 6

Solve for i for 16m = i and 2p = i

Answer 7

Because that gives you what m and p equal which you can then use back into 19 = i + m + p

Answer 8

i+m+p=19

Answer 9

yes

Answer 10

but 16m = i and 2p = i so we need the values of m and p so we divide 16 for first and 2 of the other to get m and p

Answer 11

8

Answer 12

m = i/16 and p = i/2

Answer 13

?

Answer 14

so 19 = i + i/16 + i/2

Answer 15

288/17

Answer 16

Not quiet check again. i used 16 as common denom

Answer 17

304/25

Answer 18

yes!

Answer 19

so now you know what iron is. it wants mulch right? so wasnt mulch 16m = i? and now we know i so....?

Answer 20

ok now what

Answer 21

16m = 12.16 so solve for m

Answer 22

do i div

Answer 23

yes. divide 16 across to solve for m

Answer 24

1.3

Answer 25

12.16/16 = ?

Answer 26

0.76 sorry

Answer 27

and there you have it :p

Answer 28

that was wrong

Answer 29

what were your choices then?

Answer 30

No choice i have to find the Ib

Answer 31

pretty sure it isnt wrong though. hmmm. did you include lb? does it want in lb or?

Answer 32

No the system already has Ib for me

Answer 33

just have to type the answer in

Answer 34

odd. let me re-check thats definitley the way to solve i'll give you the answer once i re-do everything.

Answer 35

ok

Answer 36

I think i had my variables mixed up. Try 16. Youre not getting penalized for trying this right? I hope not T_T

Answer 37

ok that was right thanks

Answer 38

can u help me with one more question

Answer 39

Find two consecutive even integers such that four times the first equals three times the second.

Answer 40

I'm sorry. I shouldn't have made that issue but I read the question wrong. It was saying 16 times as much mulch as iron so instead of say 16m = i it was 16i = m. :X

Answer 41

and same for potassium :p

Answer 42

can u just tell the answer for this answer, so i can rate and give u points

Answer 43

I'm not supposed to. I got in trouble last time so i'll just try to speed it up this time :p. 1 sec

Answer 44

ok

Answer 45

Ok so basically 4 times the first consecutive even integer is equal to 3 times the second consecutive even integer is basically saying:

4x = 3(x+2)

So solve for x

Answer 46

this will be really quick :p
