18 2/5 - n = -10 1/3

Wewaii [24]

Answer:

The answer is $n=28\frac{11}{15}$ .

Step-by-step explanation:

Given:

18 2/5 - n = -10 1/3.

Now, to solve the equation:

$18\frac{2}{5} - n = -10 \frac{1}{3}$

Converting the mixed fractions to improper:

⇒ $\frac{92}{5} -n=-\frac{31}{3}$

Moving the numbers on one side and variable to the other:

⇒ $\frac{92}{5} +\frac{31}{3}=n$

Now, solving the factions:

⇒ $\frac{92\times 3+31\times 5}{15}=n$

⇒ $\frac{276+155}{15}=n$

⇒ $\frac{431}{15}=n$

⇒ $28\frac{11}{15}=n$

Therefore, the answer is $n=28\frac{11}{15}$ .

Solve for x. -1+14x 12+17

tino4ka555 [31]

Answer:

x=9

Step-by-step explanation:

These two angles are equal since they are alternate exterior angles

-1 +14x = 12x+17

Subtract 12x from each side

-1 +14x-12x = 12x-12x+17

-1+2x= 17

Add 1 to each side

-1+1+2x = 17+1

2x = 18

2x/2 = 18/2

x =9

Solve 3x + 2 = 15 for x using the change of base formula log base b of y equals log y over log b. −1.594 0.465 2.406 4.465

disa [49]

<u>Answer:</u>

The value in 3x + 2 = 15 for x using the change of base formula is 0.465 approximately and second option is correct one.

<u>Solution:</u>

Given, expression is $3^{(x+2)}=15$

We have to solve the above expression using change of base formula which is given as

$\log _{b} a=\frac{\log a}{\log b}$

Now, let us first apply logarithm for the given expression.

Then given expression turns into as, $x+2=\log _{3} 15$

By using change of base formula,

$x+2=\frac{\log _{10} 15}{\log _{10} 3}$

x + 2 = 2.4649

x = 2.4649 – 2 = 0.4649

Hence, the value of x is 0.465 approximately and second option is correct one.
