The product of two rational numbers is (-28/81). If one of them is (-2/3), the find the other.
KatRina [158]

Answer:

The other rational number is \dfrac{14}{27}.

Step-by-step explanation:

First rational number is \dfrac{-2}{3}

Let other rational number is \dfrac{x}{y}

The product of two rational numbers is \dfrac{-28}{81}

According to question,

\dfrac{x}{y}\times \dfrac{-2}{3}=\dfrac{-28}{81}

Multiplying both sides by (-3/2) such that,

\dfrac{x}{y}\times \dfrac{-2}{3}\times \dfrac{-3}{2}=\dfrac{-28}{81}\times \dfrac{-3}{2}\\\\\dfrac{x}{y}=\dfrac{14}{27}

So, the other rational number is \dfrac{14}{27}.

Solve using substitution -9x+7y=-15 and -8x+y=18​
Kipish [7]

Answer:

x=-3, y=-6. (-3, -6).

Step-by-step explanation:

-9x+7y=-15

-8x+y=18

------------------

y=18-(-8x)=18+8x=8x+18

----------------------------------

-9x+7(8x+18)=-15

-9x+56x+126=-15

47x+126=-15

47x=-15-126

47x=-141

x=-141/47

x=-3

-8(-3)+y=18

24+y=18

y=18-24=-6

x=-3, y=-6.
