Answer:
b = 28/3 or 9.3
Step-by-step explanation:
b-8+2b=20
3b-8=20
3b=20+8
3b=28
Okay so the problem starts you off with the fraction (1/4). Sharing equally among 3 people would mean that you'd want to divide it by three so your equation would initially look like (1/4) / 3. Having two dividing signs is confusing so what you do is change the dividing into multiplying by the reciprocal of 3 = 1/3... This would make your expression (1/4) * (1/3) and when you simplify this you should get 1/12 as the answer.
Answer:
$2.41
Step-by-step explanation:
There are 4 quarts in a gallon. If there are 3 gallons that means there is 12 quarts (3x4=12) You then take $28.92 and divide it by 12, which will give you 2.40833333 and on and on, you round that to $2.41. I hope that helps!
This one is correct good job,anymore questions
Circumfernce=2pir
Vcylinder=lpir^2
so what you do is take circumference adnd solvefor r, then input that for r in Volume and solve for legnth
C=2pir
C/(2pi)=r
input
V=lpir^2
V=lpi(C/2pi)^2
V=lpi(c^2/(4pi^2))
V=l(c^2/4pi)
multiply both sides by (4pi)/(c^2) to clear fractio
(4piV)/(C^2)=legnth
basically if you know volume and circumference
legnth=(4pi tmes volume)/(circumference^2)
