Answer:
r = -6
Step-by-step explanation:
6(r - 8) = 8r - 36
distribute 6 into r - 8
6r - 48 = 8r - 36
add 36 to both sides
6r - 12 = 8r
subtract 6r from both sides
-12 = 2r
divide by 2 on both sides
-6 = r
Answer:
7.3
Step-by-step explanation:
For this question, you must use the distance formula. The distance formula is based around Pythagorean Theorem, so you will see some similarities.
Distance = 
X2 is 7 (X coordinate of school)
X1 is 5 (X coordinate of friend's house)
7 - 5 = 2
2^2 = 4
Y2 is 7 (Y coordinate of school)
Y1 is 0 (Y coordinate of friend's house)
7 - 0 = 7
7^2 = 49
4 + 49 = 53
= 7.2801...
