Answer:

x=\frac{9}{157} \\y=-\frac{105}{157}

Step-by-step explanation:

-6x-5y=64x+y=3

-6x-5y=64x+y

-6x-64x=y+5y

-70x=6y

divide by 2

-35x=3y

y=-(35/3)x

y+64x=3

-(35/3)x+64x=3

-35x+192x=9

157x=9

x=9/157

y=-35/3x

y=-\frac{35}{3} \times\frac{9}{157} \\y=-\frac{105}{157}

"If a number divided by 4 leaves remainder 2 or 3", then which one is the correct statement 'n why?
Hoochie [10]

Answer:

As the number is a prime number. Therefore, option 'c' is true.

Step-by-step explanation:

Let us take the number 7 and divide it by 4

\frac{7}{4}

We know that

  • Quotient\frac{Remainder}{Divisor}

as

\frac{7}{4}=1\frac{3}{4}

so the remainder is 3.      ∵ Quotient\frac{Remainder}{Divisor}

As 7 is a prime number, and when we divide the prime number 7 by 4, we get the remainder 3.

Thus, the number is a prime number. Therefore, option 'c' is true.

jok3333 [9.3K]

Answer:

$14,903.85

Step-by-step explanation:

So, Ms. Lui earns $775,000 each year. To find the weekly salary, we have to divide the annual income by the amount of weeks in a year. There are about 52 weeks in one year. Let's find the weekly salary:

\frac{775000}{52} = 14,903.85

Therefore, Ms. Lui earns $14,903.85 a week.
