20% of $5.00 is $1.00 Therefore your sale price is 1.00
Firstly, add 2 to both sides of the equation: 
Next, multiply both sides by 5/3: 
Next, square root both sides: 
Lastly, factor out i (i = √-1) and <u>your answer will be 
</u>
A=(pi)d
158.368=3.14d
d=50.436
r=25.218
Answer:
Combine like terms; 3x + 5x= 8x
Since you don't have any like terms for +8, it's going to remain the same and not change.
Answer : 3x + 5x + 8 = 8x + 8
Again with combining like terms, 4x + 4x = 8x
Answer: 4x + 4x = 8x
The third expression is going to be very similar to the last problem. 4x + 4x + 4x + 4x. We're going to add the terms together. 4+4+4+4 is equal to 16. Bring the x down and you get...
Answer: 16x
Lastly, we have -7x + 4 + 3x. Do the exact same thing we did to the other problems, combining like terms, shocking, I know. -7x + 3x= -4 and since there's no other like terms for +4, it stays the same. Therefore
Answer: -7x + 4 + 3x = -4 + 4
I hope this helps, mark as brainliest, please? :)
I am pretty sure that the answer is 15+ n or it could be 15n
