What is negative 21/9 times negative 18/7
diamong [38]

Answer:

negative 21/9 times negative 18/7  is 6

Step-by-step explanation:

The phrase negative 21/9 times negative 18/7 can be written mathematically as

-\frac{21}{9} \times -\frac{18}{7}

Lets first convert the fractions into decimal values

-\frac{21}{9} = -2.33

-\frac{18}{7} =  -2.57

Now on simplyfying

=>-2.33 \times -2.57

=> 5.988

=>6 (rounding off)

We will get a positive value because the multiplicative law states that the product of two negative number is positive

  PLZZZZZZZ HELPP  Which ordered pair is the solution to the system of equations? {y=2x−15} {4x+3y=−5} (5, −5) (4, −7) (0, 6) (7
Sophie [7]

solution is (4, - 7 )

given the equations

y = 2x - 15 → (1)

4x + 3y = - 5 → (2)

substitute y = 2x - 15 into (2)

4x + 3(2x - 15) = - 5

4x + 6x - 45 = - 5

10x - 45 = - 5 ( add 45 to both sides )

10x = 40 ( divide both sides by 10 )

x = 4

substitute x = 4 into (1) for corresponding value of y

y = (2 × 4 ) - 15 = 8 - 15 = - 7

solution is (4, - 7 )
