2x+3y=10<br> -6x-9y=30<br> elmantation method

Assoli18 [71]

Answer:

• First assign any label to the equations:

${ \tt{2x + 3y = 10 - - - \{eqution \: (a) \}}} \\ { \tt{ - 6x - 9y = 30 - - - \{equation \: (b) \}}} \\$

• Multiply equation (a) by 3

$\dashrightarrow \: { \tt{3 \times (2x + 3y = 10)}} \\ \dashrightarrow \: { \tt{6x + 9y = 30}}$

• Sum up the result with equation (b)

${ \underline{ + { \tt{ \binom{6x + 9y = 30}{ - 6x - 9y = 30} }}}} \\ { \tt{0x + 0y = 60}}$

A sculptor needs to lift a piece of marble.

Dennis_Churaev [7]

Answer:

486kg

Step-by-step explanation:

density = mass / volume

2.7 = m / (100 x 60 x 30) **** Note the conversion to cm as the density is given in g/cm.

2.7 = m / 180000

m = 486000g

Now convert to mass in kg:

486000 g x 1 kg / 1000 g = 486kg

What will 0.16 be as a fraction?

nata0808 [166]

The six is in the hundredths place so we will out the fraction as “over a hundred”, meaning 16/100. But this can be simplified to 4/25 :)

So 4/25 is your answer
