What is the answer to 3x+x/4=x+3/4

Mathematics
1 answer:
erica [24]3 years ago
5 0

Answer:x = 1

Step-by-step explanation:

3x + x/4 = x + 3/4

Subtract x from each side

2x + x/4 = 3/4

Times each side by 4

The 4 beneath the x cancels out

3/4 x 4 = 3

2x + x = 3

3x = 3

Divide each side by 3

x = 1

1 second = 2 megabytes

1\frac{1}{2}\ seconds=3\ megabytes

2 seconds = 4 megabytes

Step-by-step explanation:

Given,

Time taken to download 5 megabytes = 2\frac{1}{2}=\frac{5}{2} seconds

\frac{5}{2}\ seconds = 5\ megabytes

Multiplying both sides by \frac{2}{5} to find unit rate

\frac{2}{5}*\frac{5}{2}\ second = \frac{2}{5}*5\\1\ second = 2\ megabytes

1 second = 2 megabytes

1\frac{1}{2}\seconds = \frac{3}{2}\ seconds

\frac{3}{2}\ seconds = \frac{3}{2}*2

\frac{3}{2}\ seconds = 3\ megabytes

1\frac{1}{2}\ seconds=3\ megabytes

2 seconds = 2*2 megabytes

2 seconds = 4 megabytes
