What must be the value of n ?

jarptica [38.1K]

Answer:

Since we have a^7 on the Numerator and after simplification... No "a" was left in the expression. It simply means that all a's in the numerator was eliminated and 2a's were left in the denominator.

To eliminate a^7 and still have 2a's as a remainder in the denominator... 'n' must be equal to 9

n=9

Solve y=-1/4x+2 2x+8y=-40

PolarNik [594]

Answer:

No solution

Step-by-step explanation:

This is just a simple system of equations.

y=-1/4x+2

8y+2x=-40

Get the same variables onto their corresponding sides, so it will look like this:

y=-1/4x+2

8y=-2x-40

Now here, you have to be careful, because to solve for the system of equations, you need to make sure you are multiplying the equation proportionately.

8y=-2x+16

8y=-2x+40.

But here you see that they share the same variables in a similar format, but their values are supposed to be different, meaning that this equation is a false claim. So you would respond to the question as "no solution.

Prove sum of interior angle triangle is 180

ryzh [129]

Given :- 

A triangle ABC .

To prove :- 

Sum of interior angles of a ∆ is 180° .

Construction :-

Draw a line MCN parallel to AB .
Extend line AB to K .

Proof :- 

In ∆ ABC , we have ,

$\angle$ BAC + $\angle$ BCA = $\angle$ CBK

As sum of two interior angles of a triangle is equal to the opposite exterior angle .

Also ,

$\angle$ ABC + $\angle$ CBK = 180°

( linear pair )

Hence from above two ,

$\angle$ ABC + $\angle$ BAC + $\angle$ ACB = 180°

Hence Proved !

a hiker average is 6 3/8 kilometers per hour if he hikes 5 1/3 hours how many kilometers does he hike

maxonik [38]

He hiked approximately 34 Kilometers bc 6 3/8 is the same as 6.375 and 5 1/3 is the same as 5.333333 and those multiplied would equal 33.9997875 which rounds to about 34 Kilometers.
