Corrected question :

Solve the equation. Write your answer as an integer or simplified fraction.

8n - 7 (n - 2) = 18

Required Solution :

The given equation,

8n - 7 (n - 2) = 18

★ Multiplying -7 into (n - 2),

>> 8n - 7 × (n - 2) = 18

>> 8n - 7n + 14 = 18

★ On substracting 7n from 8n we gets,

>> n + 14 = 18

★ Now transposing 14 which is in L.H.S. into R.H.S. (Remember that sign would be . So 14 would be -14),

>> n = 18 - 14

>> n = 14

★ Therefore,

Value of n is 14.

in the afternoon the temperature was 52°F. A strong arctic cold front caused the temperature to drop 38 degrees in 4 3/4 hours.

Anvisha [2.4K]

Answer: 32 2/19°

Step-by-step explanation:

The decrease in temperature per hour will be calculated thus:

= (52 - 38) / 4¾

= 14°/4¾

= 2 18/19° per hour.

If the temperature continues to drop at the same rate, then the temperature after 2 hours will be:

= 38° - (2 18/19 × 2 hours)

= 38° - 5 17/19°

= 32 2/19°

Therefore, the temperature after 2 hours will be 32 2/19°.

For what values of y: Is the value of the fraction 5−2y 12 always greater than the value of 1−6y?

Rasek [7]

Answer:

$(5 - 2y) \div 12 > 1 - 6y$

$5 - 2y > 12 - 72y$

$- 7 > - 70y$

$7 < 70y$

$y > 1 \div 10 = 0.1$

PLEASE HELP WITH EXPLANATION

Alja [10]

Answer:

There are 2 solutions to this equation

$x=-\frac{1}{4} +i\frac{\sqrt{19} }{4} ,x=-\frac{1}{4} -\frac{\sqrt{19} }{4}$

Step-by-step explanation:

for a quadratic equation of the form ax^2 + bx + c = 0 the solutions are

$x_{1,2}=\frac{-b±\sqrt{b^{2}-4ac } }{2a}$

$x=\frac{-2+\sqrt{2^{2}-4.4.5 } }{2.4} :-\frac{1}{4}+ i\frac{\sqrt{19} }{4} \\x=\frac{-2-\sqrt{2^{2}-4.4.5 } }{2.4} :-\frac{1}{4} -i\frac{\sqrt{19} }{4}$

Log of square root of 9/25

hoa [83]

You can rid the square root and be left with log of 3/5
then you can simplify this further into: log(3) - log(5) and then get the final answer -0.2218

$\sqrt{9}/ \sqrt{25} = \sqrt{9/25}$
