12:7
because you add 7 and 5 and then there is the 7 for the book weight
Answer: 2/3ft or C
Step-by-step explanation: Solve for b in the area of a triangle equation, A=1/2bh. Multiply 1/2 by 2 on both sides to cancel it: A(2)=bh. Divide both sides by h:
=b
A = 2/5
h = 6/5
b = ?
Next, we can plug the numbers into this equation:
=b
Multiply 2 and 2/5: 4/5 / 6/5
Take the reciprocal of 6/5: 4/5 x 5/6 = 
÷
=
