Which expression is equivalent to

Damm [24]

Answer:

$\frac{(2a+1)^{2} }{50a}$

Step-by-step explanation:

$\frac{2a+1}{10a-5} * \frac{4a^{2} - 1}{10a}\\ = \frac{2a+1}{5(2a-1)} * \frac{(2a+1)(2a-1)}{10a}\\=\frac{(2a+1)^{2} }{50a}$

1.The expression given is in division so when changing to multiplication the fraction is reversed.

2.Using algebra identity $a^{2} - b^{2} = (a+b)(a-b)$ .

3. Taking the common factor 5 out.

4. Finally cancelling the like terms from the numerator and denominator.

Train A leaves a station at 8:00 and travels at 100 km per hour towards the next city. One and a half hours later, Train B, an e

Anon25 [30]

Let t be time in hours.

Train A travels at 100 km per hour, so after t hours it will be 100t km from the station.

Train B travels at 160 km per hour, but it leaves the station one and a half hours later than train A, so its time is (t-1.5) hours. After (t-1.5) hours it will be 160(t-1.5) km from the station.

Train B will overtake train A when their distances from the station are equal.
$100t=160(t-1.5) \\
100t=160t-240 \\
100t-160t=-240 \\
-60t=-240 \\
t=\frac{-240}{-60} \\
t=4$

Train B will overtake train A after 4 hours since train A left the station. It left the station at 8:00, so train B will overtake it at 12:00.

The initial equation is 25x+150=650. Since she already has 150, we can subtract that from the total to get 500. We now have that 25x=500. Divide by 25 on both sides to get 20 weeks

Outside a home, there is a 10-key keypad with the letters A, B, C, D, E, F, G, H, I, and J that can be used to open the garage i

Assoli18 [71]

Answer:

3,628,800 (aka "10!")

Step-by-step explanation:

The first letter in the code can be 10 possible letters.

Since every letter can only be used once, the second letter can only be 9 possible letters.

E.G.: If the first letter is A, the second letter is B-J.

The third letter would be 8 possible letters, than the fourth would be 7, etc.

In math form, figuring out the possible combinations would be written out as so:

10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1

An easier way to write this out would be using "10!", which stands for "10 Factorial"

The result of the above equals 3,628,800.
