Infinitely solution:

the equation,

3u+40+2u=6u-30-u

can be solved by the following steps.

3u+40+2u=6u-30-u

+2u

5u+40=6u-30-u

            -5u

40=u-30-u

+30

70=u-u

70=0

Step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

18.75 gallons
