Q13 A gardener needs to buy compost to fill this tub.
REY [17]

Answer:

  5 bags

Step-by-step explanation:

The volume of the tub is the product of its dimensions:

  V = (1.8 m)(0.5 m)(0.25 m) = 0.225 m³

There are 1000 L in 1 m³, so this volume in liters is ...

  (0.225 m³)(1000 L/m³) = 225 L

At 50 L per bag, the gardener needs ...

  (225 L)/(50 L/bag) = 4.5 bags

The gardener probably cannot purchase a partial bag, so must buy more than is needed.

The gardener must buy 5 bags of compost to fill the tub.

2x + 3 + 4x + 8 = 3x - 10
vodomira [7]

\text {Hello! Let's solve this Equation!}

\text {Your First Step is to Simplify the Equation:}

\text {(2x+4x)+(8+3)}

\text {6x+11=3x-10}

\text {The Next Step is to Subtract 3x:}

\text {6x+11-3x=3x-10-3x}\\\text {3x+11=-10}

\text {Next Step is to Subtract 11:}

\text {Q: Why Subtract 11?}

\text {A: So they cancel out. We cross them out once we subtract.}

\text {3x+11-11=-10-11}\\\text {3x=-21}

\text {The Final Step is to Divide 3:}

\text {3x/3=-21/3}

\text {Your Answer will be}

\fbox {x=-7}

\text {Best of Luck!}

\text {-LimitedX}
