Naddika [18.5K]

Answer:

Jay has 8 computer games

Step-by-step explanation:

Let

x -----> the number of computer games Sherry has

y -----> the number of computer games Jay has

z -----> the number of computer games Nairan has

we know that

$x=5y$ ----> equation A

$z=3y$ ----> equation B

$x=z+16$ ----> equation C

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

$5y=3y+16$

$5y-3y=16$

$2y=16$

$y=8$

therefore

Jay has 8 computer games

How does square root of 48 get to 4 times the square root of 3?

serg [7]

$\sqrt{48}=\sqrt{16\times 3}=\sqrt{16}\times\sqrt{3}= 4\sqrt{3}$

When 48 is factored, it factors to 4²×3. When you take the square root of that, you get 4√3.

Megan drove from her house to work at an average speed of 45 miles per hour. The drive took her

-Dominant- [34]

Answer:

Step-by-step explanation:

Since the question says that it took her 45 minutes per hour, you can use that to find the distance of the route she took.

45 miles: 60 minutes

15 miles: 20 minutes ----------------cross multiply (20x45 and then divide by 60)

Therefore, if she is going to use the same route in reverse, the distance would be 15 miles.

Use the formula for speed:

speed= distance/time

= 15/0.5 ---------- 0.5 hours is the same as 30 minutes

= 30
