Replace the x with 9, and the y with 1.
(x · y²)/-5 becomes (9 · 1²)/-5
1² is just 1, so you're doing 9 × 1 (which is = 9) over -5.
Therefore, your final answer is -9/5.
Answer:
<u>Consider the following identity:</u>
- a³ - b³ = (a + b)(a² - ab + b²)
<u>Let a = 2, b = 1/2</u>
- (2 + 1/2)(2² - 2*1/2 + 1/2²) =
- 2³ - (1/2)³ =
- 8 - 1/8
204 - 120 = 84
84/120 x 100 = 70%
answer: 70% increase
So the ratio is 40/26 = 1.54
24 ÷ 1.54 = 15.58
2x-4 = 15.58
2x = 19.58
x = 9.8
Answer:
$7.20
Step-by-step explanation:
The formula for simple interest is I = Prt, where P = principal, r = interest rate, t = time (usually in years), and I = amount of simple interest.
Thus, the answer is $7.20.
