HELPPPPPPP MEEEEE BUT PUT THE CORRECT ANSWER

Mathematics
1 answer:
Elenna [48]3 years ago
3 0

Answer:

\sf 3\left[-x+\left(2x+1\right)\right]=x-1

\sf 3\left(-x+2x+1\right)=x-1

Combine like terms:

\sf -x+2x=x

\sf 3\left(x+1\right)=x-1

Expand:

\sf 3x+3=x-1

Subtract 3 from both sides:

\sf 3x+3-3=x-1-3

\sf 3x=x-4

Subtract x from both sides:

\sf 3x-x=x-4-x

\sf 2x=-4

Divide both sides by 2:

\sf \cfrac{2x}{2}=\cfrac{-4}{2}

\boxed{\boxed{ \sf x=-2}}

When a problem involves more than one unit for a characteristic (such as length), now can you tell which unit is more appropriat
Lostsunrise [7]

Answer:

For larger measurements, we use larger unit while for smaller measurement we use smaller unit.

Step-by-step explanation:

Normally, For larger distances we make use of larger units while for smaller distances we make use of smaller units.

For example, if we consider the distance travelled by a person in some days;

For 15000 units distance; We can represent this value as 15 Kilometers

For 800 units distance; Rather than using kilometers, it would be better to represent it in meters as 8 meters.

Also, For 70 units distance; Instead of kilometers or meters, 70 cm would be a better unit of representation.

Likewise, If we consider some 3 dimensional shapes holding some substances,

For 7000 units, best unit of weight representation would be 7 Kg

For 600 units, instead of in kg, best unit of weight representation would be 600 grams

For 50 units, best unit of weight representation would be 50 grams

So, looking at the examples given in both weight and distances, we will conclude that for larger measurements, we use larger unit while for smaller measurement we use smaller unit.
