Answer:
![\large\boxed{x = 7}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7Bx%20%3D%207%7D)
Step-by-step explanation:
3x - 2(x + 3) = 4x - 9 - x
Start by multiplying 2 by the values in the parenthesis
3x - 2x + 6 = 4x - 9 - x
Subtract 3x - 2x and 4x - x
x + 5 = 3x - 9
Add 9 to both sides of the equation
x + 14 = 3x
Subtract x from both sides of the equation
14 = 2x
Divide both sides of the equation by 2
![\large\boxed{x = 7}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7Bx%20%3D%207%7D)
Hope this helps :)
Answer:
10 offices
Step-by-step explanation:
the ratio is 5/6 so if the time is doubles the number of offices cleaned also doubles.
5/6 x 2 =10/12 so, 10 offices cleaned.
Answer:
- 0.8
Step-by-step explanation:
The first thing we want to do here is simplify the expression -
( 2x + 5 ) - 2x, Distribute the "
" to elements within the parenthesis
=
2x +
5 - 2x, Focus on simplifying the expression "
2x +
5 "
=
- 2x
=
- 2x, Combine fractions
=
+ 3
=
x + 3
So we have our simplified expression "
x + 3, " with
being the coefficient of x. Our requirements are that this fraction should be expressed as a decimal, so we can simply divide the numerator by the denominator to figure that out,
- 4 / 5 = - 0.8,
Solution = - 0.8
So you can see the right angle is 90
Step-by-step explanation:
A number that is negative is less than 0, so
![3x + 6 < 0](https://tex.z-dn.net/?f=3x%20%2B%206%20%3C%200)
![3x < - 6](https://tex.z-dn.net/?f=3x%20%3C%20%20-%206)
![x < - 2](https://tex.z-dn.net/?f=x%20%3C%20%20-%202)
So this function is negative, when x is less than -2
