r-ruslan [8.4K]2 years ago
5 0

Answer:

Add -4x to both sides--> 6x+9=4x-3 and 2x+9=-3

multiply both sides by -1/4 --> -4(5x+7)=-18 and 5x-7=4.5

multiply both sides by 1/4--> 12x+4=20x+24 and 3x+1=5x+6

multiply both sides by -4--> -5x/4=4 and 5x=-16

add -4 to both sides--> 8-10x=7+5x and 4-10x=3+5x

Liula [17]

Answer:

\frac{ - 5}{54}  +  \frac{5 \times 6}{9 \times 6}  =  \frac{ - 5 + 30}{54}  =  \frac{25}{54}

\frac{15}{4}   \div  \frac{3}{8}  =  \frac{15}{4}  \times  \frac{8}{3}  =  10

10 \times  \frac{25}{54}  =  \frac{250}{54}  = 4 \times \frac{17}{27}

b )

4 \times \frac{17}{27}  =  \frac{125}{27}  =

cube root =

\frac{5}{3}

c ) square root

\frac{125}{27}  =  \frac{ \sqrt{25 \times 5} }{ \sqrt{3 \times 9} }  =  \frac{5 \sqrt{5} }{3 \sqrt{3} }
