Describe a real life multiplication situation for which an estimate makes sense
Drupady [299]
If you are trying to create a garden of potted plants, you would find out how much soil each pot needs/holds and multiply that by how many pots you plan to use. then you would go to the store for potting soil, which let’s say came in smaller packs and you need to purchase multiple. use multiplication estimation to estimate how many bags you’d need.
I know this is a dumb example...sorry this is one I remember from my fourth grade math teacher ahah

5x + 6(x - 2) - 8 (x - 3)
Alex Ar [27]

Answer:

The value of x=-4. The figure is also attached below.

Step-by-step explanation:

Considering the expression

5x + 6(x - 2) - 8 (x - 3)

If we have to find the vale of x, then

5x + 6(x - 2) - 8 (x - 3)=0

5x+6x-12-8\left(x-3\right)=0

5x+6x-12-8x+24=0

3x+12=0

\mathrm{Subtract\:}12\mathrm{\:from\:both\:sides}

3x+12-12=0-12

3x=-12

\mathrm{Divide\:both\:sides\:by\:}3

\frac{3x}{3}=\frac{-12}{3}

x=-4

Therefore, the value of x=-4. The figure is also attached below.
