Answer:
175+ braniliest pls
Step-by-step explanation:
175+
It said the sale earned OVER $25 from selling cookies at $3 dollars each so if we let r=revenue , p=price per cookie and c=number of cookies sold:
pc>r and since p=3 and r=25
3c>25 divide both sides by 3
c>25/3
Since cookies are quantized units, they must be integers so:
c>8 1/3
c≥9 or in interval notation
c=[9, +oo)
Answer:
See below.
Step-by-step explanation:
m∠A + m∠B = m∠B + m∠C
Use the subtraction property of equality to subtract m<B from both sides of the equation.
m∠A + m∠B - m<B = m∠B - m<B + m∠C
m∠A = m∠C
Answer:
a₁₃ = - 27x - 41
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 3x + 7
d = a₂ - a₁ = - 5x + 3 - (- 3x + 7)
= - 5x + 3 + 3x - 7
= - 2x - 4
Then
a₁₃ = - 3x + 7 + 12(- 2x - 4)
= - 3x + 7 - 24x - 48
= - 27x - 41
Answer:
3.92$
Step-by-step explanation:
The first step is to deduct 20% of 4.50 from 4.50.
20% of 4.50 is 0.2 x 4.50 = .90
4.50 - 0.90 = 3.60
That's the new price without the sales tax.
Now we need to add 9% of 3.60 to 3.60 to get the final cost.
9% of 3.60 is .09 x 3.60 = 0.32
3.60 + .32 = $3.92
