J/4 - 8 < 4
<u> + 8 + 8 </u> *add 8 to both sides to cancel -8.
j/4 < 12
<u>*4/1 *4/1 </u> *multiply 4/1 to both sides to cancel 1/4
j < 48
j should be less than 48 to make the inequality true.
example: j = 47
j/4 - 8 < 4
47/4 - 8 < 4
11.75 - 8 < 4
3.75 < 4
Any number below 48 will end up with an answer less than 4. if j is 48 and above, the inequality is false because the answer arrived at will be equal to or greater than 4.
So,
Home ---- gym = 3.6 mi.
gym ---- store = .7 mi.
store ----- home = x
3.6 + .7 + x = 7.2 mi.
Collect Like Terms
4.3 + x = 7.2
Subtract 4.3 from both sides
x = 2.9
The distance from the store to her home is 2.9 miles.

Answer:
100800°
Step-by-step explanation:
One degree section is 360°
Turning 280 times will give 280 x 360 = 100800°
To solve this problem you must apply the proccedure shown below:
a)
1. You must rewrite the formula for calculate the volume of a sphere:
V=4πr³/3
2. Susbtitue r by d/2 and then solve for d, as following:
V=4π(d/2)³/3
V=(4πd³/8)/3
V=4πd³/24
24V=4πd³
d³=24V/4π
d=∛(24V/4π)
d=2∛(3V/4π)
b) V=4πr³/4
r=d/2
r=(2/3 cm)/2
r=1/3 cm=0.33 cm
V=0.15 cm³
