Subtract 2 from both sides

3x+2-2=5-2

3x=3

Divide both sides by 3

3x/3= 3/3

The answer is ×=1

-4 1/2x - 3/7= 1/4<br>find x
DiKsa [7]
- 4(1/2)x - (3/7) = (1/4)
- 4(1/2)x = (1/4) + (3/7)
- (9/2)x = (7+12)/28
-(9/2)x = 19/28
x = (19/28) * 2 / 9
x = (19/14) / 9
x = 19 / (14*9)
x = 19 / 126

Dante bought a new graduated cylinder for his chemistry class. It holds 1,345.6 milliliters of liquid. If the cylinder has a rad
pentagon [3]
The formula for a cylinder's volume  is
V = π r² h
V = 1345.6
π = 3.14
r = 5.8 cm

1345.6 = 3.14 * 5.8^2 h Multiply 3.14 and 5.8^2 together.
1345.6 = 105.6 h  Divide by 105.6
1345.6 / 105.6 = h
h = 12.73 cm <<<< answer.
 I don't see anything wrong with what I've done but I don't see the answer anywhere. Estimating 1345 can be rounded to 1300. 
pi * 5.8^2 = 3 * 35 = 105 which we could round to 100.

1300 / 100 about = 13 So the answer should be in the region of 100.

I cannot see any reason to believe there is an error. If there is something that has not been copied correctly, I'd like to know what it is.
