35 POINTS. I need help! Please!
topjm [15]
There is no solution  for the first one

if you eliminate y   you get 2 equations
-13x - 13z = -25
-13x - 13x = -15    

- there is no solution to theses

a23  means the element in the second  row and the 3rd column

so its -5

A farmer needs 3x2 − 4x + 10 seeds for each of x3 + 5x − 20 fields. What expression would represent the seeds the farmer needs t
Fittoniya [83]

Answer:

Step-by-step explanation:

(3x^2-4x+10)(x^3+5x-20) =3x^5-4x^4+25x^3-80x^2+130x-200

x=1 is not a good value since when you plug it in you get -126 and you can't have a negative number of seeds.

Please help me.i don't get it.
alukav5142 [94]

Answer:

See below.

Step-by-step explanation:

The addition method is a good choice in this case since you have x in one equation and -x in the other equation, and x and -x add to zero, eliminating x.

 x - 5.5y = -14

-x + 2.6y = 8.2

Add the equations. x and -x ad to zero, eliminating x. Then solve for y.

-2.9y = -5.8

Divide both sides by -2.9

y = 2

Substitute 2 for y in the first original equation, and solve for x.

x - 5.5y = -14

x - 5.5(2) = -14

x - 11 = -14

x = -3

Solution: x = -3; y = 2

Since the coefficients of y in the two original equations are not opposites, the addition method would not be the best method to use to solve for y first.

The convex polygon below has 7 sides. find the value of x
Brrunno [24]
The given convex polygon has 7 sides

Hence its sum of interior angles is given by the formula , (number of sides-2)x180°

=> (7-2) x 180°

=> 5 x 180°

=> 900°

The sum of all angles must be equal to 900°

The given six angles are :

139°,126°,106°,129°,141°,112° , x°

=> 139+126+106+129+141+112+x = 900°

=> 753 + x = 900

=> x = 900-753

=> x = 147°

Hence 147° is the required answer.
