It is 12 (explanation: unit rate is per unit so 16/16 mile or 1 mile = x minutes so if you multiple 1/16 by sixteen and do the same on the other side (3/4 times 16), you get 20 (hope this helps!)
This is the image the points form, if you know your quadrilaterals, this should make it easier to picture and label. Need any further explanation?
No, because it is not a straight line
s = 6 + e
s + e = 28
We can use this system of equations to find the exact values of s and e.
We have a current value of s, so we can find the exact value of e now.
e + e + 6 = 28
<em><u>Combine like terms.</u></em>
2e + 6 = 28
<em><u>Subtract both sides by 6.</u></em>
2e = 22
<em><u>Divide both sides by 2.</u></em>
e = 11
Now we have an exact value of e, and can solve for the value of s.
s = 6 + 11
s = 17
