Answer:
6(2a+4)-4(3a-4)= (12a+24) +(-12a+16) = 40
Answer: 180 tickets for $40
Step-by-step explanation:
To answer this question, we need to find a pattern;
15 / 3 = 5
60 / 15 = 4
-> If you divide, we find a pattern of the quotient with 5... 4... so we can assume the next is 3
Using this pattern;
60 * 3 = 180 tickets for $40
Answer:
(x) = 
Step-by-step explanation:
let y = f(x) , then rearrange making x the subject
y = 6x + 7 ( subtract 7 from both sides )
y - 7 = 6x ( divide both sides by 6 )
= x
Change y back into terms of x with x =
(x) , then
(x) = 
Answer:
