They would be 69 and 70.
Your equation would be x + (x + 1) = 139
X would be the first integer and x + 1 would be the second
You would then solve the equation to get x as 69
X + 1 would then be 70
Step-by-step explanation:
the second one as the -2x-3 is only on the second one
Answer:
The old fish tank hold <u>18.84 cubic feet</u> of water.
Step-by-step explanation:
Given:
An old fish tank in the form of a circular cylinder and it is 2 feet in diameter and 6 feet tall.
Now, to find the cubic feet of water the fish tank hold.
Dimensions of old fish tank are:
<em>Diameter is 2 feet so. we find the radius first.</em>
Radius (
) = 
Height (
) = 
Now, to get the cubic feet off water the tank hold we put formula:
<u><em>(Taking the value of π as 3.14.)</em></u>

Therefore, the old fish tank hold 18.84 cubic feet of water.
