He ate 2/3 of the pizza in half an hour so to eat 1/3 of the pizza it to 15 minutes so the answer is 45 minutes
For the first one:
x-1<span><-1
Add one on both sides.
x</span><span><0
For the second one:
8x+9</span><span>≥41
Subtract nine on both sides.
8x+</span><span>≥32
Divide by eight on both sides.
x</span><span>≥4
HOPE THIS HELPS YOU! ^_^</span>
If you let the width be x, then the length will be 2x + 3. The perimeter P is
twice the width plus twice the length, i.e.,
P = 2*x + 2*(2x + 3) = 2x + 4x + 6 = 6x + 6.
So if the perimeter is 66 cm then 66 = 6x + 6 ---> 6x = 60 ---> x = 10 cm.,
and so if the perimeter is at most 66 cm., the width can be at most 10 cm..
7/8 gallon of water/ (1/2 hr)= 1.75 gallons of water/ hr.
The swimming pool is leaking 1.75 gallons of water/ hr.
Hope this helps~
