I’m not understanding how you can solve for this?

-1/12

Step-by-step explanation:

You have to substitute the given values of x and y into the expression 4xy². So now the expression would look like this: 4×-1/3×1/4².

Now just simplify from there.

4×-1/3×1/16

-4/3x1/16

-4×1/3×16

-4/48

-1/12

Not sure if my answer is really right but hope this helped nudge you in the right direction

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

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.
