1. n-3n=14-4n
n-3n+4n=14
2n=14
n=7
2. -8n+4(1+5n)=-6n-14
-8n+4+20n=-6n-14
12n+6n=-14-4
18n=-18
n=-1
3. -10+x+4-5=7x-5
x-7x=-5+10-4+5
-6x=6
x=-1
4. -6n-20=-2n+4(1-3n)
-6n-20=-2n+4-12n
-6n+2n+12n=4+20

OK!!!!!!!!!!!!!!!1
Step-by-step explanation:
Answer:
The pizza was $20
Step-by-step explanation:
$2/10%= $X/100%
So triangle has 3 sides
represent them as x,y,z
so lets say x=shortest side
y=2nd side
z=longest side
x is 1/2 of the second side
x=1/2(y)
shortest side is 1/3 of the longset side
x=1/3(z)
how does the triangle compart the longest side (z)
x+y+z=perimiter
solve to subsitute and convert all values to z
x=1/2y
2x=y
2(1/3z)=y
2/3(z)=y
and x=1/3(z)
therefor, subsitute so that there are only z terms
1/3(z)+2/3(z)+z=perimiter
add like terms
3/3(z)+z=p
z+z=p
2z=p
the peimiter is 2 times of the longest side
Answer:
They lost 8% of the games they played.
Step-by-step explanation:
If the total percent is 100% then we just subtract 92% from that, to get 8% left.
