1) given 6x = 4x + 140
2) subtract 4x from both sides => 6x - 4x = 4x - 4x + 140
=> 2x = 140
3) divide both members by 2 => 2x / 2 = 140 / 2
=> x = 70
4) Answer: x = 70
Yes as the even times the occurrence of negative signs makes the answer positive.
Answer:
W=8
Step-by-step explanation:
The result is number
where:
![r=(120+120\cdot\frac{d}{100})+(120+120\cdot\frac{d}{100})\cdot\frac{25}{100}](https://tex.z-dn.net/?f=r%3D%28120%2B120%5Ccdot%5Cfrac%7Bd%7D%7B100%7D%29%2B%28120%2B120%5Ccdot%5Cfrac%7Bd%7D%7B100%7D%29%5Ccdot%5Cfrac%7B25%7D%7B100%7D)
Hope this helps.
