7x=3y+45<br> 4x+5y=19 what’s the answer and show work

makkiz [27]

Answer:

x = 6, y = -1.

Step-by-step explanation:

7x = 3y + 45

4x + 5y = 19.... (1)

Rearranging the first equation:

7x - 3y = 45-----(2)

Multiply equation (1) by 3 and equation (2) by 5:

12x + 15y = 57

35x - 15y = 225

Adding :

47x + 0 = 282

x = 282 / 47 = 6.

To find the value of y substitute x = 6 into equation (2):

7(6) -3y = 45

-3y = 45 - 42 = 3

y = 3/-3 = -1.

Find the quotient: 15x^4y^2-30x^2y^3+45xy/5xy is ________. when this quotient is divided by _____the result is x^3y-2xy^2+3

gogolik [260]

$\dfrac{15x^4y^2-30x^2y^3+45xy}{5xy}=\dfrac{15x^4y^2}{5xy}-\dfrac{30x^2y^3}{5xy}+\dfrac{45xy}{5xy}\\\\=3x^{4-1}y^{2-1}-6x^{2-1}y^{3-1}+9=3x^3y-6xy^2+9\\\\=3(x^3y-2xy^2+3)\\\\Used:\\\\\dfrac{a^n}{a^m}=a^{n-m}\\\\Answer:\\....\underline{3x^3y-6xy^2+9}...\ \ \ ...\underline{3}...$

Answer:

The given expression is

$3 + (\frac{(2+8)2}{4} \times(\frac{1}{2} )^4)= \hspace{0.3cm}3 +( \frac{10 \times 2}{4}\times \frac{1}{2^4} ) \hspace{0.3cm} = \hspace{0.2cm} 3 + ( \frac{5}{16})$ = 3.3125

Step-by-step explanation:

The given expression is

$3 + (\frac{(2+8)2}{4} \times(\frac{1}{2} )^4)= \hspace{0.3cm}3 +( \frac{10 \times 2}{4}\times \frac{1}{2^4} ) \hspace{0.3cm} = \hspace{0.2cm} 3 + ( \frac{5}{16})$ = 3.3125
