Just multiply by 4 to isolate x; because 4 isn't negative, u keep the sign the same.
Answer:
16,000
Step-by-step explanation:
to round to the nearest thousand you must look at the thousands place and then look to the number next to it
if the number is 0 1 2 3 or 4 the thousands place stays the same
if the number is 5 6 7 8 or 9 the thousands place goes up one
in this case it is 0
so it stays the same
16,000 is your answer
Volume of a cylinder is h x r^2 x pi
You have the volume and radius of each one, so taking 188.4=(2)^2 x 3.14 x h1, you can solve this equation for the height h1. Likewise, for the other graduated cylinder you take 314=2^2 x 3.14 x h2, and then solve for h2.
To get the difference in heights, just take h2-h1 after solving the equations for h2 and h1
Answer:
-7.7
Step-by-step explanation:
-18 divided by 7 = -2.57
-2.57 multiplied by 3 = -7.7
-7.7
I used simplistic form for this equation as the numbers where quite long.
