Answer:
$73.25
Step-by-step explanation:
35 + 2.55(15) = 38.25 + 35 = 73.25
Answer:
x = 3, v = -8
Step-by-step explanation:
Substitute x.

[5 •
= -73 - 11v]
Isolate v.
5
= -73 - 11v
v = -8
Substitute v.
x = 
x = 3
Answer:
x = 0 or x = 5/2
Step-by-step explanation:
Solve for x over the real numbers:
x^2 sqrt(2 x - 5) = 0
Split into two equations:
x^2 = 0 or sqrt(2 x - 5) = 0
Take the square root of both sides:
x = 0 or sqrt(2 x - 5) = 0
Square both sides:
x = 0 or 2 x - 5 = 0
Add 5 to both sides:
x = 0 or 2 x = 5
Divide both sides by 2:
Answer: x = 0 or x = 5/2
