We use the rule of BODMAS here which is Bracket Of Division Multiplication Addition Subtraction
y2+2x+3w-z
(8x8)+(2x4)+(3x7)-1
64+8+21-1
=92

4x - red marbles
x/2 - blue marbles

$x+4x+\frac{x}{2}=33|\cdot2\\
2x+8x+x=66\\
11x=66\\
\boxed{x=6}\\\\
\boxed{4x=24}\\\\
\boxed{\frac{x}{2}=3}

Maggie has 4 3/5 of icing to decorate cakes for a bake sale. Each container will cover 20 1/4 in2. How many square inches will i

ExtremeBDS [4]

Answer:

$93\frac{3}{20} \ square \ inches$ .

Step-by-step explanation:

Given:

Maggie has 4 3/5 container of icing to decorate cakes for a bake sale.

Each container will cover 20 1/4 square inches.

Question asked:

How many square inches will it cover if she uses all of her icing ?

Solution:

Total number of container Maggie has = $4\frac{3}{5}$

Each container will cover = $20\frac{1}{4}$ square inches.

Now, we can find easily that how many square inches it will cover by using all of her icing by unitary method:

Each container will cover = $20\frac{1}{4}$

$4\frac{3}{5}$ container will cover = $20\frac{1}{4}\times4\frac{3}{5} =\frac{20\times4+1}{4} \times\frac{5\times4+3}{5} \$

$=\frac{81}{4} \times\frac{23}{5} =\frac{1863}{20} =93\frac{3}{20}\ square\ inches$

Thus, it will cover $93\frac{3}{20} \ square \ inches$ ,if she uses all of her icing.
