Let the number of cookies David has = c
Number of cookies given to Jeff = 8
So cookies left with David = c-8
David splits the cookies in half with Tod. So cookies left with David are =

Same number of cookies are with Tod = 
He finds the number of cookies that Tod has is 1/2 the difference of C and 8. Write an expression to represent the number of cookies that Tod has.
Hence, number of cookies with Tod are= 
Answer:
w² + 12w + 2
Step-by-step explanation:
( - 2w² + 5w - 4 ) + ( 3w² + 7w + 6 )
= 3w² - 2w² + 5w + 7w + 6 - 4
= 1w² + 12w + 2
= w² + 12w + 2
Answer:
=10t-6-7.5t = 6-0.5t
= 2.5t- 6 = 6-0.5t
= 2.5t+0.5t = 6+6
= 3t = 12
= t = 12/3
t = 4
Therefore the answer is 4
The second one. The absolute value sign makes all the y values positive, meaning the negative 4 will turn into positive 4.
