Mathematics
1 answer:
NNADVOKAT [17]3 years ago
4 0

Answer:

9 Km/h

Step-by-step explanation:

Walking 3 Km for 20 minutes from the definition of speed, it's distance covered per unit time. Here, the distance covered is expressed per unit hour.

Speed=\frac {distance}{time}

Substituting 3.5 Km for distance and time for 20 minutes

To convert time into hours, we divide the minutes by 60 hence time=20/60=1/3 hours

Speed=\frac {3 Km}{1/3 hours}=9 Km/h

Therefore, the speed is 9 Km/h

What is the answer to 8(2× - 6) =96​
Arisa [49]

Answer:

the answer is 3

x= 3

Step-by-step explanation:

8(2× - 6) =96​

multiply 8 on the right side of equation we get

16x -48 = 96

16x= 96-48

16x = 48

divide by 16 on both side we get

simplify

16x / 16 = 48 / 16

x = 3

So that the value of x we get after the equation solved is x = 3

hopefully it will be brainliest for you

thank you !

Help!
lord [1]

Answer:

  1

Step-by-step explanation:

The square of the value in the empty space is the constant in the expanded expression. That is ...

  [ ]² = 1

The value in the space is ...

  [ ] = √1 = 1

The filled-in equation is ...

  (3x -1)² = 9x² -6x +1

_____

The expansion of the square of a binomial is ...

  (ax -b)² = a²x² -2abx +b²

Above, we used the constant term to find 'b', but we could also have used the linear term:

  -6x = -2(3)bx . . . . . a=3 in this problem

  1 = b . . . . . . . divide by -6x
