70 divided by 7 equals 10.
Tamara practiced the piano for 10 minutes on Monday. <span />
The answer for this problem is x=12.
Answer:
B
Step-by-step explanation:
Point-slope form: y - y1 = m(x - x1)
(x1, y1) = a coordinate
m = slope
Now, substitute with the given information.
y - 1 = 1/6(x + 7)
Hope This Helped! Good Luck!

Step-by-step explanation:
Let assume that,
So,
Given,
perimeter = 200 feet
We know that,
Perimeter = 2(length + wide)
So,

So length = x + 40 = 30 + 40 = 70 feet
