( 8 x 2 ) + ( 8 x 5 ) = __ x ( 2 + 5 )

8

Step-by-step explanation:

( 8 x 2 ) + ( 8 x 5 ) = 56

(2+5) = 7

56/7 = 8

I think its __1__ because nothing can be multiplied by x

(8×2)+(8×5) = 1*x(2+5)

16 + 40 = 2x + 5x

56= 7x

x=8

hope it helps

answer: 2/4

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
