Solve the system using any method.<br> x= - 4y+7<br> -2y+3x=9
Arte-miy333 [17]

The solution to the given system of equation is (25/7, 6/7)

<h3>System of equation</h3>

Given the system of equation expressed as:

x= - 4y+7 ........... 1

-2y+3x=9 ...........2

Substitute the equation 1 into 2 into have:

-2y + 3(-4y+7) = 9

-2y + 3(-4y) + 3(7) = 9

-2y - 12y + 21 = 9

Collect the like terms

-14y = 9- 21

-14y = -12

y = 6/7

Substitute y = 6/7 into equation 1;

x =-4y + 7

x = -4(6/7) + 7

x= -24/7 + 7

x = -24+49/7

x = 25/7

Hence the solution to the given system of equation is (25/7, 6/7)

What is the sum of the interior angles, each interior angle, the central angle, and each exterior angle of a pentagon, a hexagon
WITCHER [35]
<span>Sum of Interior Angles: Formula: (n-2) * 180
-Pentagon: 540</span>°<span>
-Hexagon: 720</span>°<span>
-Octagon: 900</span>°<span>
-Nonagon: 1260</span>°<span>
-Decagon: 1440</span>°<span>
-Dodecagon: 1800</span>°

Each interior Angle: Formula: [(n-2)*180] / n
-Pentagon: 108°
-Hexagon: 120°
-Octagon: 135°
-Nonagon: 140°
-Decagon: 144°
-Dodecagon: 150°

The sum of the exterior angles of each polygon stated above is equal to 360 degrees. Using the formula: (180-interior angle) * n

The central angle is formed by making a circle in the middle and divide it by the number of sides. Therefore, CA = 360 /n
-Pentagon: 72°
-Hexagon: 60°
-Octagon: 45°
-Nonagon: 40°
-Decagon: 36°
-Dodecagon: 30°

The bases of the prism below are right triangles. The volume of the prism is 3360 units33 . Find the height of the prism.
lana66690 [7]

Answer:

14

Explanation:

Given:

Volume of the prism = 3360 units^3

To find:

The height of the prism

We'll use the below formula to determine the height(h) of the prism;

\begin{gathered} Volume(V)=Area(A)\text{ of the triangular base * Height\lparen H\rparen of the prism} \\ V=(\frac{b*h}{2})*H \\ 3360=(\frac{16*30}{2})*H \\ 3360=240*H \\ H=\frac{3360}{240} \\ H=14 \end{gathered}

So the height of the prism is 14
