Answer:
300
Step-by-step explanation:
Let's call N the total number of televisions. We have that 240 televisions make up of 80% of the total number of televisions, so we can rewrite it as
where 0.80 means 80 % (
. By solving the equation above, we find
So, the total number of televisions is 300.
If you would like to simplify the expression (x - 8y) - (2x - 4y), you can do this using the following steps:
(x - 8y) - (2x - 4y) = x - 8y - 2x + 4y = -x - 4y
ax + by = -x - 4y
a = -1
b = -4
The value of b would be -4.
If you would like to simplify the expression (4x - 6) - (3x + 6), you can do this using the following steps:
(4x - 6) - (3x + 6) = 4x - 6 - 3x - 6 = x - 12
The correct result would be x - 12.
All triangles have a total of 180° in them.
So to find x, simply take 50° and 100° from 180°:
x = 180 - 100 - 50
= 30°
So x = 30°, and thus option D
Hey there! :)
Answer:
x = -4/3, 0, 4.
Step-by-step explanation:
Starting with:
6x³ - 16x² - 32x = 0
Factor out the greatest common factor between each term, or 2x:
2x(3x² - 8x - 16) = 0
Factor the expression inside the parenthesis:
2x(3x +4)(x - 4) = 0
Use the Zero Product Property to solve the equation:
2x = 0
x = 0
---------
3x + 4 = 0
3x = -4
x = -4/3
-------------
x - 4 = 0
x = 4
-------------
Therefore, the solutions to this equation are:
x = -4/3, 0, 4.
