Answer:
n = 25
Step-by-step explanation:
-2n + 15 = n - 60
Subtract 15 to both sides
-2n = n - 75
Subtract n to both sides
-3n = -75
Divide -3 to both sides
n = 25
Best of Luck!
Step-by-step explanation:
3/7y + 3/4x = 3/5
y = -3/4x.7/3 +3/5.7/3
y = -7/4x +7/5
so the slope is -7/4
You add the given areas together (15.9+19.6+17.5) so the answer is 53.
