Because both of the equations = s, we can set them equal to each other.
c + 7 = 2c - 13. Now we can solve for c. Once you have found c, you can substitute it back into either of the two original equations and solve for s.
Answer: 7.5 dollars. Also known as 7.50
Step-by-step explanation: 1 roll is 5 dollars. You have 1 and a half rolls. So five, plus 2.5 (five divided into half). 7.5 dollars.
<span>∫(sinx cosx)^2dx = ∫(1/2sin 2x)^2 dx = 1/4∫sin^2 2x dx = 1/4∫1/2(1 - cos 4x)dx = 1/8∫(1 - cos 4x) dx = 1/8[x - sin 4x / 4] + c = 1/32(4x - sin 4x) + c
