Answer:

150 miles

Step-by-step explanation:

If 1/2 of an inch is 20 miles, we can assume that 1/4 of an inch is 10 miles, since half of 1/2 is 1/4 and 1/2 of 20 is 10.

Equipped with this information, we can divide 3 by 1/2 or multiply 3 by the reciprical, 2/1 to get how much we should multiply 20 by.

3*2=6

20*6=120

Then we can multiply 10 by 3 and add that on our answer, since there are still 3/4s left and 1/4=10 miles.

10*3=30

120+30=150

The actual distance is 150 miles.

Hope this helps!

Find the slope and y-intercept of the line through the points (-3,-4) and (0,-1)​
Alja [10]

Answer:

Slope=1, y-intercept=-1.

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-(-4))/(0-(-3))

m=(-1+4)/(0+3)

m=3/3

m=1

y-(-4)=1(x-(-3))

y+4=x+3

y=x+3-4

y=x-1

y=mx+b where m=slope and b=y-intercept

so you have slope of 1 and y-intercept of -1

What number do you divide by 12 to get 9
finlep [7]

Well I don't know.  Let's figure it out together.

You said (a number) divided by 12 gives you 9 .

A fraction is the easiest way to show division, so
you can write this equation:

               (number) / 12  =  9

Now you can multiply each side of the equation by  12 .
When you do that, you have ...

                 number   =   9 x 12

                 <em>number   =    108</em> .

Now you know how to find it.  That's even better than just
having the answer.
