2x - 3 < 11 or 8x -10 < 82:  <span>X < 23/2
<span>
Part 1</span>
</span>2x-3<11
Add 3 both sides
2x-3+3<11+3
Refine
2x<14
Divide by 2 on both sides
2x / 2    /   14 / 2
Refine
x < 7
<span>
Part 2</span>
8x-10<82
Add 10 to both sides
8x-10+10<82+10
Refine
8x<92
Divide by 8
8x / 8   /   92 / 8
Refine
x < 23 / 2

Answer:

Area of parallelogram is 150 square ft

Step-by-step explanation:

Given the parallelogram in the figure whose height is 10 ft and base length is 15 ft.

Area of parallelogram is base \times height

                                       = 15\times 10ft^2

                                       = 150 square ft

now we have to decompose this parallelogram into rectangles and triangles and then to determine the shape.

The given parallelogram KLMN can be decomposed into 2 triangles and one rectangle.

2 right angled triangles KPL and NOM by construction

KL^{2}=KP^{2}+PL^{2}=10^{2}+2^{2}                                          =100+4=104

⇒ KL=\sqrt104=10.2 ft=MN         (∵ KLMN is a parallelogram)

Hence, dimension of triangles are 10 ft, 2 ft and 10.2 ft

Now rectangle KPON with dimension 15 ft and 10 ft because KP and NO are perpendiculars on LM.

Solve each system using elimination.<br> − 5 = −10 <br> − + = 6
Maksim231197 [3]

The values of (x, y) are (-5, 1), if the equations x-5y=-10 and -x+y=6 are solved by elimination method.

Step-by-step explanation:

The given is,

                      x-5y=-10................................(1)

                    -x+y=6.....................................(2)

Step:1

           Equation (2) is multiplied by -1 ( Eqn (2) × -1 )

                      x-y=-6..................................(3)

Step:2

         Substrate the equation (1) and equation (3),

                                      x-5y=-10

                                        x-y=-6

          ( - )

         After the Subtraction equation becomes,

                   (x-x)+(-5y+y)=(-10+6)

                                (0)+(-4y)=(-4)

                                            -4y=-4

                                                 y=1

Step:3

           By using y value find value of x,

                                  x-5y=-10

                             x-(5)(1)=-10

                                           x=-10+5

                                           x=-5

Step:4

           Check for solution,

                                  -x+y=6

                              -(-5)+1=6

                                             6=6

           Both sides are equal so answer is corrected

Result:

         The values of (x, y) are (-5, 1), if the equations x-5y=-10 and -x+y=6 are solved by elimination method.

Find the areas of the trapezoids
Gennadij [26K]

Answer:

figure 1 - 10.5 unit^2

figure 2 - 12 unit^2

Step-by-step explanation:

<u>figure 1</u>

1. find the area of the rectangle

<em>3*2 = 6 unit^2</em>

2. find the area of the triangle

<em>(3*3)/2 = 4.5 unit^2</em>

3. add the area of the rectangle and the area of the triangle together. The sum would be the area of the trapezoid.

<em>6 + 4.5 = </em><u><em>10.5 unit^2</em></u>

<u>figure 2</u>

1. find the area of the rectangle

<em>2*4 = 8 unit^2</em>

2. find the area of both triangles

<em>(1*4)/2 = 2 unit^2</em>

3. add the area of the rectangle and the area of both triangles together. The sum would be the area of the trapezoid.

<em>8 + 2 + 2 = </em><u><em>12 unit^2</em></u>
