Yes, it is very important otherwise some teachers may count the problem wrong.
Answer:
Advance tickets-$15
Same-day tickets-$20
Step-by-step explanation:
let x be the cost of advance tickets and y cost of same-day tickets:
Given that there were 40 advance and 25 same-day tickets for a total of $1100:
#Make x the subject in i and substitute in ii:
Hence, advance tickets cost $15 each while same-day tickets cost $20 each.
B.) the length of the spring increases by 0.006 cm for every gram added to it.
y = 0.006x + 11.50
where:y = length of the spring in centimetersx = mass added to the spring in grams11.50 = the first number in the sequence0.006 = the common difference among numbers in the sequence.
x y1 11.5 + 0.006(1) = 11.50 + 0.006 = 11.506 2 11.5 + 0.006(2) = 11.50 + 0.012 = 11.5123 11.5 + 0.006(3) = 11.50 + 0.018 = 11.5184 11.5 + 0.006(4) = 11.50 + 0.024 = 11.5245 11.5 + 0.006(5) = 11.50 + 0.030 = 11.530
For every 1 gram added, the length of the string increases by 0.006cm
hope this helps
Divide both sides by -12
X=72/-12 now let's simplify 72/-12 = -72/12 so x= -72/12 simplify 72/12= 6
X= -6
