Answer:

181.044m²

Step-by-step explanation:

First, work of the surface area of the base (bottom rectangle area)

Formula : base × height

6×2=12m²

Formula : LW+L

For the 8.8 bit i got 83.734 (sorry i can't be asked right now to put down all my working out)

and for the 9 i got 85.31

add them all together we get 181.044

Can someone please help me??

Answer:

I is clear that, the linear equation $5x+12=5x-7$ has no solution.

Step-by-step explanation:

<u>Checking the first option:</u>

$\frac{2}{3}\left(9x+6\right)=6x+4$

$6x+4=6x+4$

$\mathrm{Subtract\:}4\mathrm{\:from\:both\:sides}$

$6x+4-4=6x+4-4$

$6x=6x$

$\mathrm{Subtract\:}6x\mathrm{\:from\:both\:sides}$

$6x-6x=6x-6x$

$0=0$

$\mathrm{Both\:sides\:are\:equal}$

$\mathrm{True\:for\:all}\:x$

<u>Checking the 2nd option:</u>

$5x+12=5x-7$

$\mathrm{Subtract\:}5x\mathrm{\:from\:both\:sides}$

$5x+12-5x=5x-7-5x$

$\mathrm{Simplify}$

$12=-7$

$\mathrm{The\:sides\:are\:not\:equal}$

$\mathrm{No\:Solution}$

<u>Checking the 3rd option:</u>

$4x+7=3x+7$

$\mathrm{Subtract\:}7\mathrm{\:from\:both\:sides}$

$4x+7-7=3x+7-7$

$\mathrm{Simplify}$

$4x=3x$

$\mathrm{Subtract\:}3x\mathrm{\:from\:both\:sides}$

$4x-3x=3x-3x$

$\mathrm{Simplify}$

$x=0$

<u>Checking the 4th option:</u>

$-3\left(2x-5\right)=15-6x$

$\mathrm{Subtract\:}15\mathrm{\:from\:both\:sides}$

$-6x+15-15=15-6x-15$

$\mathrm{Simplify}\$

$-6x=-6x$

$\mathrm{Add\:}6x\mathrm{\:to\:both\:sides}$

$-6x+6x=-6x+6x$

$\mathrm{Simplify}$

$\mathrm{Both\:sides\:are\:equal}$

$\mathrm{True\:for\:all}\:x$

Result:

Therefore, from the above calculations it is clear that, the linear equation

$5x+12=5x-7$ has no solution.

Each marble bag sold by Lucy's Marble Company contains 7 yellow marbles for every 5 green marbles. If a bag has 45 green marbles

Elan Coil [88]

Answer:

63 yellow marbles

Step-by-step explanation:

You can set up this equation as a proportion:

7/5 = x/45

Divide 45 by 5 to see what 7/5 must be multiplied by to get to x/45.

You should get 9, so also multiply 7 by 9 to get this:

7/5 = 63/45

This shows that there are 63 yellow marbles for 45 green marbles.

Please thank, rate, and mark brainliest! :)
