Answer:
$34.88
Step-by-step explanation:
If the discount is 20%, then the sale price is 80% of the full (original) cost:
0.80($40.00) = $32.
Sam has to pay 9% sales tax on this $32. The total cost of his order would then be 1.09($32) = $34.88. If desired, you could write this as the equivalent $32 + 0.09($32).
(0.3m )³
note that 0.3 × 0.3 × 0.3 = 0.027, hence
0.027m³ = (0.03m)³
Answer:
father sends 7 more
19-12=7
Step-by-step explanation:
Answer: b= 45
Step-by-step explanation:
Step 1: Subtract 5b from both sides.
2b+23−5b=5b−112−5b
−3b+23=−112
Step 2: Subtract 23 from both sides.
−3b+23−23=−112−23
−3b=−135
Step 3: Divide both sides by -3.
−3b
/-3 = -135/-3
(2x-3)(x+5)=0 is the factored form
x=3/2, x=-5
So r=1.5 and s=-5
r-s=1.5-(-5)
r-s=6.5
