anonymous · Answer

$$n+\left( n-2 \right)\times \frac{ 70 }{ 100 }=8.5 $$

bookworm14 · Answer

why would you have 2 (n)s in the problem >

bookworm14 · Answer

and what would be the value of "n"

anonymous · Answer

is the answer correct?

bookworm14 · Answer

I don't know because i have to write an equation and solve for "X" but i fi get this wrong i have to start all over, and im just really trying to figure it out

bookworm14 · Answer

I thought the equation might be$$(n-2)+\frac{ 70 }{ 100 } =8.5$$

bookworm14 · Answer

in which case n=9.8

anonymous · Answer

multiply by 100
$$100 n+70 n-70 *2=\frac{ 85 }{ 10 }*100$$
170 n=850+140
170 n=990
$$n=\frac{ 990 }{ 170 }=\frac{ 99 }{ 17 }$$
After increasing n becomes 8.5
so n <8.5

anonymous · Answer

first n is the number 
second n is for to calculate increase.

bookworm14 · Answer

i got it wrong , here is the explanation they gave me:

bookworm14 · Answer

now i have to start over ;-;

anonymous · Answer

instead of n they are saying n-2 becomes 8.5 after increase.
i thought n becomes 8.5 after increase.

bookworm14 · Answer

hmm do you think you could assist on about 5 more , it started me over with new questions

anonymous · Answer

sure

bookworm14 · Answer

make that 4, i just got one right (its khan academy i have to get 5 correct in a row to pass the topic) here is the quest, i will try to solve also

anonymous · Answer

3x+2=50

anonymous · Answer

find x

bookworm14 · Answer

I got $$\frac{ 50-2 }{ 3 }=x$$

but yours looks more accurate 

x=16 i think

anonymous · Answer

3x=50-2=48
$$x=\frac{ 48 }{ 3 }=16$$

bookworm14 · Answer

your equation was right ..here is the next one

anonymous · Answer

$$\frac{ c }{ 2 }+1.2=3.7$$

bookworm14 · Answer

$$(3.7-1.2)*2=c$$ 

why are mine turning out so different from yours?

bookworm14 · Answer

mine is the one solving for c correct? or is it your because it wants us to write an equation solving for C

bookworm14 · Answer

mine was right

anonymous · Answer

both are correct
$$\frac{ c }{ 2 }=3.7-1.2$$
$$c=\left( 3.7-1.2 \right)*2$$

I know, but mine was worder the way they wanted
