Answer:

$x = \frac{ - 3b}{4} \: or \: b$

Step-by-step explanation:

$\frac{1}{b + x} = \frac{3b}{2 {x}^{2} } - \frac{1}{x}$

$= > \frac{1}{b + x} = \frac{3b - 2x}{2 {x}^{2} }$

$= > 2 {x}^{2} = (b + x)(3b - 2x)$

$= > 2 {x}^{2} = 3 {b}^{2} - 2bx + 3bx - 2 {x}^{2}$

$= > 2 {b}^{2} = 3 {b}^{2} + bx - 2 {x}^{2}$

$= > 3 {b}^{2} + bx - 4 {x}^{2} = 0$

$= > 3 {b}^{2} + 4bx - 3bx - 4 {x}^{2} = 0$

$= > b(3b + 4x) - x(3b + 4x) = 0$

$= > (3b + 4x)(b - x) = 0$

Hence,

$x = \frac{ - 3b}{4} \: or \: b$

What number is 15% of 43

Annette [7]

Step-by-step explanation:

So when a question asks what is x% of the y number. It's asking you to convert the x into decimal form by dividing by 100 and then multiply it by y. This gives you the equation: $y * \frac{x}{100}$ which gives you x% of y. so 15% of 43 is $43 * \frac{15}{100} = 6.45$ . 43% of 300 is $300 * \frac{43}{100} = 129$ .

the 12% of what number is 43 is a bit more tricky. It's asking you to instead find a number in which 12% of it is equal to 43. So instead of plugging solving for the percentage (which is already given) you solve for y. This gives you the following equation: $y * \frac{12}{100} = 43$ . Now all you do is calculate 12/100 which gives you $y * 0.12 = 43$ . now divide both sides by 0.12 to solve for y. This gives you $y = 358.\overline{33}$

43 is what percent of 106? This question is also a bit tricky, but instead of solving for y, you're solving for x. So plug in the known values, which gives you the equation: $106 * \frac{x}{100} = 43$ . Divide both sides by 106 to get $\frac{x}{100} \approx 0.406$ and now multiply both sides by 100. this gives you $x \approx 40.57$ which is the answer 40.57%

What percent of 43 is 6. This is asking the same thing just in a different way. So percentage = unknown, entire number = 43, entire number * percentage = 6. With these values we get the equation: $43 * \frac{x}{100} = 6$ . Divide both sides by 43 to get $\frac{x}{100} \approx 0.140$ now multiply by 100 to get $x \approx 13.95$ which is the answer 13.95%

Please help me!!! Will give the brainlyest!!!!

alina1380 [7]

Hey there!!

How do we find the determinant ?

Ans = ad - bc : determinant

In the given matrix ,

a = -5

b = 1

c = 1

d = 4

Determinant = ( -5 ) ( 4 ) - ( 1 ) ( 1 )

... - 20 - 1

... -21

Option ( c )

Hope it helps!
