BaLLatris [955]3 years ago

Step-by-step explanation:

<u>Remember:</u>

X = 2.5

Y = 1.5

Z = 1

The chart:

         X             Y           Z

I      10000    7000    8000

II     6000     10000   5000

X

The first column represents X. Since X's value is 2.5, we multiply both those numbers by 2.5.

10,000*2.5=25,000

6000*2.5=15,000

These are the values of X.

Y

The second column represents Y. Since Y's value is 1.5, we multiply both of the values by 1.5.

7,000*1.5=10,500

10,000*1.5 = 15,000

These are the values of Y.

Z

The last column represents Z. Since Z's value is 1, we do not need to multiply the numbers, since they are already multiplied by 1.

8,000

5,000

These are the values of Z.

ADDING

Now that we have are 6 numbers solved, all we have to do is add them all together.

(25+15+10.5+15+8+5)\\25,000+15,000+10,500+15,000+8,000+5,000=78,500

Our final answer: $78,500 is the total. (first option)

It is so because all its sides are equalto 10cm.
opposite angles are equal. in a parallelogram opposite angles are equal but all sides aren't equal but in case of a rhombus it is so.

Lesechka [4]
The best way I can explain the elimination method is, it's a method where you either add or subtract equations in order to get rid of a variable.

A rectangular garden is 6 feet long and 4 feet wide. A second rectangular garden has dimensions that are double the dimensions o
Talja [164]

Percent change is 100%

Step-by-step explanation:

  • Step 1: Find the perimeter of the first garden when length = 6 ft and width = 4 ft

Perimeter = 2 (length + width)

                = 2 (6 + 4) = 2 × 10 = 20 ft

  • Step 2: Find the perimeter of the second garden when length = 12 ft and width = 8 ft (∵ dimensions are doubled)

Perimeter = 2 (12 + 8) = 2 × 20 = 40 ft

  • Step 3: Find the percent change in perimeter

Percent Change = Final value - initial value/Initial Value × 100

                            = (40 - 20/20) × 100

                            = 1 × 100 = 100%

Solve the simultaneous equation y-2x+1=0 and 4x^2+3y^2-2xy=7
Lapatulllka [165]

The first equation is y-2x+1=0

y=2x-1 (Equation 1)

The second equation is 4x^{2}+3y^{2}-2xy=7 (Equation 2)

Putting the value of x from equation 1 in equation 2.

we get,

4x^{2}+3(2x-1)^{2}-2x(2x-1)=7

4x^{2}+3(4x^{2}+1-4x)-4x^{2}+2x=7

by simplifying the given equation,

12x^{2}-10x-4=0

6x^{2}-5x-2=0

Using discriminant formula,

D=b^{2}-4ac

D=25-4 \times 6 \times -2 = 73

Now the formula for solution 'x' of quadratic equation is given by:

x=\frac{-b+\sqrt{D}}{2a}  and  x=\frac{-b-\sqrt{D}}{2a}

x=\frac{5+\sqrt{73}}{12}  and x=\frac{5-\sqrt{73}}{12}

Hence, these are the required solutions.
