PLEASE HELP<br>1.6x-(x-2.8)=(0.2x+1.5)-0.7<br><br>Solve for x
skelet666 [1.2K]
The answer is

1.6x-(x-2.8)=(0.2x+1.5)-0.7

1.5-0.7

1.6x-(x-2.8)=0.2x+0.8

1.6x-x

0.6x+2.8=0.2x+0.8

2.8-2.8 0.8-2.8

0.6x=0.2x-2

0.6x-0.2x 0.2x-0.2x

0.4x=-2

0.4x/0.4 -2/0.4

X=-5

Suppose an amount increases by 100%, then decreases by 100%. Find the final amount. Would the situation change if the original i
Anarel [89]
Well to solve this, lets plug in some numbers. Lets assume that for now, the starting number is 2. If it increases by 100%, bringing it up to 4, then decreases 100%, it is brought down to zero. Now one thing to note is that any number decrease by 100% is automatically zero. Watch, we start with two, it is then increased by 150%, bringing it up to 5, then decreased by 100%, bringing it back down to zero. In conclusion, 100% cannot be specified as a value, but rather a relation. 100% represents the entire number, meaning that if you are decreasing a number by 100%, you are basically subtracting the number by itself!

V: es el volumen de un cubo = 216 m³

a: es la arista del cubo =?

La arista del cubo es:

a = \sqrt[3]{V} = \sqrt[3]{216 m^{3}} = 6 m
