I didn’t understand how to solve this, i’d be happy if someone explained thank you

kolbaska11 [484]

Answer:

Option (E)

Step-by-step explanation:

$\frac{a}{b}=\frac{c}{d}=k$

$\frac{a}{b}=k$

$b=\frac{a}{k}$ ------(1)

$\frac{c}{d}=k$

$d=\frac{c}{k}$ -------(2)

Since, $\frac{6a+24}{md+6b}=k$

By substituting the values of b and d from equation (1) and (2),

$\frac{6a+24}{\frac{mc}{k}+\frac{6a}{k}}=k$

$\frac{k(6a+24)}{6a+mc}=k$

$\frac{6a+24}{6a+mc}=1$

6a + 24 = 6a + mc

mc = 24

m = $\frac{24}{c}$

Therefore, Option (E) will be the correct option.

What is the solution to ln (x2 - 16) = 0?

bogdanovich [222]

ANSWER

$x = \pm \sqrt{17}$
EXPLANATION

The given equation is

$ln( {x}^{2} - 16) = 0$

Take antilogarithm of both sides to base e.

${e}^{ ln( {x}^{2} - 16) } = {e}^{0}$

This will simplify to

${x}^{2} - 16 = 1$

Group like terms to obtain,

${x}^{2} = 1 + 16$

${x}^{2} = 17$

Take square root of both sides to get,

$x = \pm \sqrt{17}$

Jack can run a mile in 9, 1/3 minutes. How long will it take for him to run 3, 1/2 miles?

BARSIC [14]

If you turn 9 1/3 in to a decimal and 3 1/2 in a decimal also

9 1/3 = 9.3 and 3 1/2 =3.5
9.3+3.5 =12.8
12.8=12 4/5

The mean age of 5 people in a room is 40 years. A person enters the room. The mean age is now 40. What is the age of the person

ad-work [718]

Answer:

Step-by-step explanation:

5 people in the room have 5*40 = 200 years altogether

a new person is X years old.

Now 6 people have (200 + x) years altogether.

Mean age of 6 people is (200+x)/6. and it is also = 40.

So,

(200+x)/6 = 40

200 + x = 240

x = 40
