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

Jada Elena and Lin walked a total of 37 miles last week. jada walked 4 more miles that elena, and Lin walked 2 more miles than j

MA_775_DIABLO [31]

Answer:

Jada walked $13\ miles$

Elena walked $9\ miles$

Lin walked $15\ miles$

Step-by-step explanation:

Let

x----> total miles walked by Jada

y----> total miles walked by Elena

z----> total miles walked by Lin

we know that

$x+y+z=37$ -----> equation A

$x=y+4$ -----> $y=x-4$ ------> equation B

$z=x+2$ ------> equation C

Substitute equation C and equation B in equation A and solve for x

$x+(x-4)+(x+2)=37$

$3x=37+2$

$3x=39$

$x=13\ mi$

Find the value of y

$y=13-4=9\ mi$

Find the value of z

$z=13+2=15\ mi$

therefore

Jada walked $13\ miles$

Elena walked $9\ miles$

Lin walked $15\ miles$
