Answer:
k = 8
Step-by-step explanation:
8(10 - k) = 2k
First, distribute within the parenthesis,
80 - 8k = 2k
Add 8k to both sides of the equation
80 = 10k
Divide both sides by 10 to get your answer
8 = k

Answer:
Erie to Rochester is 145 miles
Step-by-step explanation:
If we designate the points of interest as C, E, and R, we are told that ...
CE + ER = CR . . . . . the various distances are segments of a straight line
For CE = 94 and CR = 239, we can fill in the given information and solve for ER.
94 + ER = 239
ER = 239 -94 . . . . . . subtract 94 from both sides of the equation
ER = 145
The distance from Erie to Rochester is 145 miles.

B. y =
Step-by-step explanation:
I. Given x = 15 and y = 4
4 =
4 = 2+2
4 = 4 true
II. Give x = 0 and y = 2
2 =
2 = 0 + 2
2 = 2 true
III. Given x = -15 and y = 0
0 =
0 = -2 + 2
0 = 0 true
Good luck.
