Answer:

(11/7)x + (3/7)y

Step-by-step explanation:

Perform the indicated multiiplication. We get:

(6/7)x - (2/5)y + (5/7)y + (5/7)x

Now combine like terms, obtaining: (11/7)x + (3/7)y

An alternative expression would be (1/7)(11x + 3y)

san4es73 [151]

Step-by-step explanation:

5x + 5y = -5 , when y = 1

5x + 5.1 = -5

2. a) How many milliseconds (ms) are in 1 second? 1. b) How many microseconds (μs) are in 1 second? 2. c) How many nanoseconds (

olchik [2.2K]

Answer and explanation:

a) How many milliseconds (ms) are in 1 second?

1 second = 1000 milliseconds

1 second = $10^3$ milliseconds

b) How many microseconds (μs) are in 1 second?

1 second = 1000000 microseconds

1 second = $10^6$ microseconds

c) How many nanoseconds (ns) are in 1 millisecond?

1 millisecond = 1000000 nanoseconds

1 millisecond = $10^6$ nanoseconds

d) How many microseconds are in 1 millisecond?

1 millisecond = 1000 microseconds

1 millisecond = $10^3$ microseconds

e) How many nanoseconds are in 1 microsecond?

1 microsecond = 1000 nanoseconds

1 microsecond = $10^3$ nanoseconds

f) How many kilobytes (KB) are in 1 gigabyte (GB)?

1 gigabyte = 1000000 kilobytes

1 gigabyte = $10^6$ kilobytes

g) How many kilobytes are in 1 megabyte (MB)?

1 megabyte = 1000 kilobytes

1 megabyte = $10^3$ kilobytes

h) How many megabytes are in 1 gigabyte?

1 gigabyte = 1000 megabytes

1 gigabyte = $10^3$ megabytes

i) How many bytes are in 20 megabytes?

1 megabytes = 1000000 bytes

20 megabytes = 20000000 bytes

20 megabytes = $2\times 10^7$ bytes

j) How many kilobytes are in 2 gigabytes?

1 megabyte = 1000 kilobytes

2 megabyte = 2000 kilobytes

2 megabyte = $2\times 10^3$ kilobytes

DiKsa [7]

Answer:

Step-by-step explanation:

Measure of angle J K H + measure of angle J K L = 180 degrees

True.

Measure of angle J K L + measure of angle J L K + measure of angle K J L = 180 degrees

True. The sum of all interior angles = 180

Measure of angle J K H = measure of angle J L K =
