Answer:

1  :

Step  2  :

Equations which are never true :

2.1      Solve :    2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    2x+1 = 0

Subtract  1  from both sides of the equation :

                     2x = -1

Divide both sides of the equation by 2:

                    x = -1/2 = -0.500

One solution was found :

                  x = -1/2 = -0.500

Show step by step......​
tankabanditka [31]

Answer:

Step-by-step explanation:

Amount paid for first 100 watches = (65% of 80) *100

                                                        =\frac{65}{100}*80*100\\\\= 65*80\\= 5200

Amount paid for next 50 watches = (55% of 80) * 50

                                                        = \frac{55}{100}*80*50\\\\= 55 * 8 * 5\\\\= 2200

Remaining watches = 280 -(100+ 55)

                                 = 280 - 155 = 125

Amount paid for 125 watches = (45% of 80) *125

                                                  = \frac{45}{100}*80*125\\\\= 45 * 20 * 5\\\\= 4500

Amount received by the watch maker = 5200 + 2200 + 4500

                                                               = £ 11900

A rectangle has an area of 20 square feet a similar rectangle has an area of 180 square feet what is ratio of the areas of these
Evgen [1.6K]

Answer:

The ratio of the areas of the smaller rectangle to the larger rectangle is  \frac{1}{9}

Step-by-step explanation:

we know that

if two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z-----> the scale factor

x-----> the area of the smaller rectangle

y----> the area of the larger rectangle

so

z^{2}=\frac{x}{y}

substitute the values

z^{2}=\frac{20}{180}

simplify

z^{2}=\frac{1}{9}

That means, the area of the larger rectangle is 9 times the area of the smaller rectangle

z=\frac{1}{3} ------> the scale factor

That means, the dimensions of the larger rectangle is 3 times the dimensions of the smaller rectangle
