The two numbers would be 12 and 8 because 12 is 4 more than 8 and so the sum of 12 and 8 is 20.

X=y+4 
x+y=20

now substitute the x for (y+4) in the second equation
(y+4)+y=20
2y+4=20
2y=16
y=8
now substitute 8 for y in the first equation 
x=8+4
x=12
so y=8 and x=12

In what quadrant would the ordered pair (-5, 4) be located?<br><br> I<br> II<br> III<br> IV
statuscvo [17]
Ok, so
 Quadrants are found on coordinate planes. So the first number tells you to go on the X axis. It goes this way ---------
you look on the left side side of the origin (zero) and go to -5
since the second umber will be found on the Y axis, and is positive, go up to 4.
That is how you find your point.  The qudrants are counted like this.
2 1 
3 4
The answer is Quadrant 2

qaws [65]

Answer:

It moved because of this:

Step-by-step explanation:

the number 10 has one 0 in it.

you move the decimal place over how many times depending on how many 0s there are, so because there is <u>one</u><u> </u>0 in 10, you move it over <u>once</u>.

hope this helped!

Boston , Massachusetts, and buffalo, New York, are hit by snowstorms that last 3 days . Boston accumulates snow at a rate of 1.5
stich3 [128]

Question is ;

Complete question is;

Boston , Massachusetts, and buffalo, New York, are hit by snowstorms that last 3 days . Boston accumulates snow at a rate of 1.5 feet every 36 hours. Buffalo accumulates snow at a rate of 0.01 inches every minute.

Which city accumulates more snow in 3 days? How much more snow?

Answer:

- Boston accumulates more snow in 3 days.

- It accumulates 0.6 ft of snow more than Boston

Step-by-step explanation:

Boston accumulates 1.5 feet of snow every 36 hours.

Number of hours in 3 days = 24 × 3 = 72 hours.

Thus, In 72 hours, Boston would have accumulated; (1.5 × 72)/36 = 3 feet of snow.

Now, Buffalo accumulates 0.01 inches of snow every minute.

In 3 days, number of minutes we have = 60 × 24 × 3 = 4320 minutes

Thus, total snow accumulated in 3 days = 0.01 × 4320/1 = 43.2 inches

Now, let's convert this to ft;

12 inches = 1ft

Thus; 43.2 inches = 43.2 × 1/12 = 3.6ft

Thus, Buffalo accumulates more snow in 3 days.

It accumulates 0.6 ft of snow more than Boston
