Which number can each term of the equation be multiplied by to eliminate the decimals before solving? -m+0.02+2.1m=-1.45-4.81m
Andrews [41]
The number that each term of the equation be multiplied by to eliminate the decimals before solving -m+0.02+2.1m=-1.45-4.81m

It would be better to group all similar numbers.
<span>-m+0.02+2.1m=-1.45-4.81m
</span>-m + 2.1m + 4.81m = -1.45 - 0.02
5.91m = -1.47

The equation shown above, in order for us to eliminate the decimal, 
we need to divide 5.91.

Hard I need help plz someone help!

Answer:

  8 gallons

Step-by-step explanation:

Each rectangular face of the monument has an area of ...

  A = bh = (9 ft)(39 ft) = 351 ft^2

The triangular face on top of that rectangle has an area of ...

  A = (1/2)bh = (1/2)(9 ft)(10 ft) = 45 ft^2

So, one side of the monument has an area of ...

  one side = (351 ft^2) +(45 ft^2) = 396 ft^2

The total area of all four identical sides is ...

  surface area = (4)(396 ft^2) = 1584 ft^2

__

Each gallon covers 199 ft^2, to the number gallons required is ...

  (1584 ft^2)/(199 ft^2/gal) ≈ 7.96 gal

Since only whole gallons can be purchased, 8 gallons of paint must be bought.
