Fraction form please

pochemuha

Answer:

$\frac{108}{2}$ or $54$

Step-by-step explanation:

Use the volume, I'm guessing, formula, $v=l*w*h$

Convert $4\frac{1}{2}$ to an improper fraction using the rule:

$a\frac{b}{c}=\frac{ac+b}{c}$

$4\frac{1}{2}=\frac{4*2+1}{2}\\ \\\frac{9}{2}$

Multiply

$\frac{9}{2}*\frac{4}{1} *\frac{3}{1}$

Simplify

$\frac{9*4*3}{2*1*1}\\ \\\frac{108}{2}$

Simplify

$\frac{108}{2}=54$

Done.

Find the product.

4vir4ik [10]

Answer :

$6{y}^{4} {z}^{2} + 12 {y}^{3} {z}^{2}-3 {y}^{3} {z}+3 {y}^{2} {z}^{2}$

Step-by-step explanation :

To find the product of

$3 {y}^{2} z(2 {y}^{2} z + 4yz - y + z)$

First we expand the bracket ,

it implies that, we use the expression outside the bracket to multiply individual expressions inside the bracket.

Hence

$3 {y}^{2} z(2 {y}^{2} z + 4yz - y + z)$

$= 3 {y}^{2} z(2 {y}^{2} z) + 3 {y}^{2} z(4yz) - 3 {y}^{2} z(y )+3 {y}^{2} z( z)$

we now apply the law of indices

${a}^{m} \times {a}^{n} = {a}^{m+n}$

meaning, when you are multiplying two expressions with the same bases , repeat one of the bases and add the exponents.

Then, simplify to obtain

$= 6{y}^{4} {z}^{2} + 12 {y}^{3} {z}^{2}-3{y}^{3} {z}+3 {y}^{2} {z}^{2}$

Solve this system of linear equations. Separate

Mice21 [21]

Answer:

x=3,y=-10

Step-by-step explanation:

First, we add 21 to both sides of the first equation

13x=-21-6y

+21 +21

13x+21=-6y Now divide by -1 to make it positive

/-1 /-1 /-1

-13x-21=6y

Now we have to subtract 36 on both sides of the second equation

-8x=36+6y

-36 -36

-8x-36=6y

Since both equations equal 6y we can solve the equation by making them "equal" each other

-13x-21=-8x-36 Add 36 to both sides

+36 +36

-13x+15=-8x Add 13x to both sides

+13x +13x

15=5x Divide by 5

/5 /5

x=3

Now use the x value to solve

13(3)=-21-6y

39=-21-6y Add 21 to both sides

+21 +21

60=-6y

/-6 /-6

y=-10

Hope this helped!
