Will represent as such
number of 37 inch tvs=x
number of 58 inch tvs=y
number of 50 inch tvs =z
x is double of (y+z)
x=2(y+z)
y=z
therefor
x=2(y+y)=2(z+z)=4y=4z
x=4y=4z
y=$4800
z=$2000
x=$1800
4800y+2000z+1800x=168000
undistribute the 100
100(48y+20z+18x)=100(1680)
divide the whole thing by 100
48y+20z+18x=1680
divide the whole thing by 2
24y+10z+9x=840
y=z
24y+10z=34y or 34z
34y+9x=840
convert 9x to y by multiply 4
9x times 4=36y or 36z
34y+36y=840
70y=840
divide both sides by 70
y=12
y=z
z=12
x=4z
x=4(12)
x=48
they should stock:
12 50 inch tvs
12 58 inch tvs
48 38 inch tvs
Answer:
d = 1/2
Step-by-step explanation:
5/6 = 1/3 + d
~Find common denominators
5/6 = 2/6 + d
~Subtract 2/6 to both sides
3/6 = d
~Simplify
1/2 = d
Best of Luck!
Answer:
With the rule: d(n) = d(n-1) x (-5), we have:
d(1) = 8
d(2) = d(1)x(-5) = 8x(-5) =-40
d(3) =d(2)x(-5) = -40x-5 =200
Other way:
d(n) = d(n-1) x (-5) => d(n) = d(1)x(-5)^(n-1)
d(3) = d(1)x5^(3-1) =8x5^2=8x25 =200
