Answer:
. r=9 inches is the answer.
Let number of driveways , she shoveled on Sunday = x
And for 4 driveways , Kendra charges = 4*11=44
Therefore,
143 = 44 + 11x
And that's the model for the given situation .
Subtracting 44 from both sides,
143-44 = 11x
99 = 11x
Dividing both sides by 11
x = 9
Therefore she shoveled 9 driveways on Sunday .
Answer:
a^2 + b^2 = c^2
a^2 + 32^2 = 58^2
a^2 + 1024 = 3364
a^2 = 2340
a = 48.37
