Answer:
x = 22/15
Step-by-step explanation:
2.5(6x-4)=10+(1.5+0.5)
Combine like terms
2.5(6x-4)=10+(2)
2.5(6x-4)=12
Divide each side by 2.5
6x-4 = 4.8
Add 4 to each side
6x = 8.8
Divide by 6
6x/6 = 8.8/6
x = 88/60
x = 22/15
She began with 10. She has 11. Take away the 6 she just bought and that leaves 5. But she had sold half and ended up with 5. So she started with 10!
This is the equation: 3x-2=5x+15
<span>you combine like terms: 3x-3x-2=5x-3x+15 </span>
<span>the 3x on the left cancles out: -2=2x+15 </span>
<span>subtract 15 on both sides: -2-15=2x+15-15 </span>
<span>the 15 on the right cancles out:--17=2x </span>
<span>divide by 2: -17/2=2x/2 </span>
<span>x equals negative 8.5: x=-8.5</span>

Answer:
6 feet
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = 2πr ← r is the radius, thus
2πr = 12π ( divide both sides by 2π )
r =
= 6
