Answer: x= 12

Step-by-step explanation: These are vertical angles. Vertical angles are equal.

(15x-29)= (12x+7) subtract 12x from both sides. 3x-29 = 7. Add 29 to both sides. 3x = 36. Divide both sides by 3. x= 12

It is 42 1/2 miles from Eaton to Baxter and 37 4/5 miles from Baxter to Wellington. How far is it from Eaton to Wellington if yo
mina [271]
All you need to do is add the miles from Eaton to Baxter and from Baxter to Wellington to get your answer...

42 + 37 = 79 

Now we need to add the fractions 

\frac{1}{2} +  \frac{4}{5} = ...


To add we need a common denominator. 
2 and 5 can both go into 10, so that will be a our common denominator. 
Now you have... 
\frac{5}{10} + \frac{8}{10} = \frac{14}{10}
which is equal to 1 \frac{2}{5}
add that to the 79 we got earlier ...

The toal and final answer is 80 \frac{2}{5} miles !
Hope I helped and remember to vote this as the brainliest answer ! :)

Solve for X. The Triangles in each pair are similar
Klio2033 [76]

Answer:

x = 7

Step-by-step explanation:

In this question, we need to find what the value of x is.

To do so, we need to find the value of the change of the triangle, since the triangles are basically the same

We know to get from 18 to 27, we would need to multiply 18 by 1.5.

This means that the triangle "BCD" is increasing from 1.5 to get "JKL"

With this knowledge, we also know that side CB, 10, needs to increase by 1.5

When you multiply 10 by 1.5, you get 15.

The triangle side "JK" is the same side as "CB", so we need to find what makes the value of 15 for the "JK" side.

To do this, solve 3x-6 for 15.

3x - 6 = 15

Add 6 to both sides.

3x = 21

Divide both sides by 3

x = 7

The x-variable would be 7.

College Calculus - hyperbolic functions (see attachment)
morpeh [17]

Answer:

g(x) = sinh^-1 ( ln(7x^6 +3) / sqrt( 8+cot( x^( 3+x))))

Step-by-step explanation:

Using the fundamental theorem of calculus

Taking the derivative of the integral gives back the function

Since the lower limit is a constant when we take the derivative it is zero

d/dx \int\limits^x_4 {g(t)} \, dt  = g(x)

g(t) = sinh^-1 ( ln(7t^6 +3) / sqrt( 8+cot( t^( 3+t))))

Replacing t with x

g(x) = sinh^-1 ( ln(7x^6 +3) / sqrt( 8+cot( x^( 3+x))))
