sove for x.
1. 2/3(x+4)=8
round the results to the nearest tenth and then to the nearest hundredth:
2. 57.124/10.104
3. 13.254(3.145)

2/3(x+4)=8
Clear the fraction by multiplying both sides by 3.
2(x+4)=24
Clear the parentheses.
2x + 8 = 24
Move the 8 to the other side.
2x = 248
combine terms
2x = 16
Divide both sides by 2
2x/2 = 16/2
x = 8
round the results to the nearest tenth and then to the nearest hundredth:
2. 57.124/10.104
3. 13.254(3.145)
2 is
57.124/10.104 = 5.6535
I don't know what you've been taught on rounding (positive OR negative numbers) so I'll let this go.
