Answer: x + 6
Step-by-step explanation:
We will use the order of operations, also known as PEMDAS. See attached. Please note that we cannot do what is in the parentheses first because we have a variable, so we will distribute the 2 into it. Since this is an expression, I do not believe we can fully solve for x, but can only simplify.
Given:
2(3/5x+3)
Distribute:
2 * (3/5x) + (2 * 3)
6/5x + 6
Answer:
x + 6
Get all on one side
add 9x+4 both sides
4x^2+9x+4=0
use quadratic formula
in form
ax^2+bx+c=0
x=
a=4
b=9
c=4
x=

Answer:
3 pizza slices.
Step-by-step explanation:
We have been given that Desmond ordered his favorite pizza with 12 slices. Sadly, he could finish only 75% of the whole pizza.
As Desmond ate 75% of 12 slices, so left number of slices will be equal to 25% of 12 slices.
Therefore, 3 pizza slices were left.
