185 tickets
You can get this by setting up a system of equations and solving by substitution.
x + y = 364 (number of tickets)
2x + 4.5y = 1175.50 (Cost)
Put it in an equation;
it is given that 36 is the price after the 40% discount, so;
36=X*40%
X here is the original price
36=X*(40/100)
40X=3600
X=90$
Hope this helps.
W -width of the brand name TV, L - length of the brand name TV;
3/8 W = 12
W = 12 : 3/8 = 12 · 8/3 = 32 in
3/8 L = 24
L = 24 : 3/8 = 12 · 8/3 = 64 in
Answer: A ) 32 inches by 64 inches.
Answer:
Using ∣x∣>a⇒x<−a or x>a, we get
∣3x−7∣>4⇒3x−7<−4 or 3x−7>4
