The expression -4 (-11 + 4n) – 3(- 2n + 9) is equivalent to the expression 17 — 10n.
<h3>What is an equivalent expression?</h3>
The equivalent is the expressions that are in different forms but are equal to the same value.
The expression is given below.
⇒ -4 (-11 + 4n) – 3(- 2n + 9)
On simplifying, we have
⇒ 44 – 16n + 6n – 27
⇒ 17 — 10n

Since all of the variables are y^3, all we have to do is the addition and subtraction of the whole numbers...
2y^3 - 3y^3 + 3y^3 - 4y^3 =
-2y^3
***Notice that the -3y^3 and 3y^3 just cancel out so all you have to do is the
2-4 = -2
Piece of cake :)
Answer:
$115.67
Step-by-step explanation:
given that the markdown rate is 53%, that means that the markdown is 53% of the original price, or,
markdown = 53% of $229.99 = 0.53 x 229.99 = $121.89
sale price before tax = Original Price - Markdown
= 229.99 - 121.89
= $108.10
sales tax = 7% of sale price before tax
= 0.07 x 108.10
= $7.57
Final price = price before tax + tax
= 108.1 + 7.57
= $115.67
If you make the denominators similar, you get
6/8 and 7/8
6/8 is smaller, so no, 3/4 isn't bigger than 7/8
Answer:
∠Q ≈ 42.969, ∠P ≈ 52.03, QR ≈ 15.036
Step-by-step explanation:
Law of sines:
13/sin Q = 19/sin 85°
=> sin Q = 13 × sin 85°/19
=> Q = sin^-1 (13 × sin 85°/19)
=> Q ≈ 42.969
∠P=> 180 - 85 - 42.969 ≈ 52.03
QR/sin 52.03° = 19/sin 85°
=> QR = sin 52.03° × 19/sin 85°
=> QR ≈ 15.036
