Answer:

  3/(x +1) -4/(x +1)^2

Step-by-step explanation:

The partial fraction expansion will be of the form ...

  A/(x+1)^2 +B/(x+1)

We can find the values of A and B by writing the sum of these terms:

  = (A +B(x +1))/(x +1)^2

Then we require ...

  B = 3

  A +B = -1   ⇒   A = -4

So, the desired expansion is ...

  3/(x +1) -4/(x +1)^2

At an electronic store, 4 phones and 3 laptops together cost $1580.62. The total cost of 2 laptops and 5 cameras is $1340.90. If
Mashutka [201]

Answer:

$2,677.72

Step-by-step explanation:

L = 3C

P

4P + 3L = 1,580.62

2L + 5C = 1,340.90

4P + 5L + 3C = ?

2L + 5C = 1,340.90

6C + 5C = 1,340.90

11C = 1,340.90

C = 121.90

121.90 * 3 = 365.70

L = 365.70

4P + 3L = 1,580.62

365.70 * 3 = 1,097.10

4P = 483.52

P = 120.88

C = 121.90

L = 365.70

P = 120.88

4P + 5L + 3C = ?

4(120.88) + 5(365.70) + 3(121.90) = 2,677.72

What is 24% of 234 and it has to be 20 characters long
frozen [14]

Answer:

56.16

We need to determine 24% of 234 now and the procedure explaining it as such

Step 1: In the given case Output Value is 234.

Step 2: Let us consider the unknown value as x.

Step 3: Consider the output value of 234 = 100%.

Step 4: In the Same way, x = 24%.

Step 5: On dividing the pair of simple equations we got the equation as under

234 = 100% (1).

x = 24% (2).

(234%)/(x%) = 100/24

Step 6: Reciprocal of both the sides results in the following equation

x%/234% = 24/100

Step 7: Simplifying the above obtained equation further will tell what is 24% of 234

x = 56.16%

Therefore, 24% of 234 is 56.16
