Question

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)

Answer 1

2/3(x+4)=8
<b>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 = 24-8
combine terms
2x = 16
Divide both sides by 2
2x/2 = 16/2
x = 8</b>


round the results to the nearest tenth and then to the nearest hundredth:
2. -57.124/10.104
3. -13.254(-3.145)
<b>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. </b>
