First you do 2 x 3x which will be 6x you then look to see whether there is a plus or minus next we see that it is a minus after this you do 2 x 5 which is 10 so the first bit is 6x - 10 we then look to see whether we have a plus or a minis we look to see that it is a plus you then work out the next bracket so you do 3 x 2x to give us 6x we see that we need to add a plus then do 3 x 3 which is 9 together it is 6x - 10 + 6x + 9 so now we have to simplify it so you do 6x + 6x which is 12x then do -10 + 9 which is -1 so the answer is 12x - 1

<u>Answer:</u>

(i) Total cost of the flat is Rs. 540000.

(ii) Expenditure incurred on labour is Rs. 150000

<u>Step-by-step explanation:</u>

According to the question, cement cost is Rs. 112500, which represents 75° in the pie chart.

(i) The total cost of the flat is represented by the total 360° in the pie chart.

∴ Using unitary method

75° represents Rs. 112500

⇒ 360° represents = \frac{112500}{75}  ×  360

                                = Rs. 540000

∴  Total cost of flat = Rs. 540000

(ii) Similarly, to calculate the cost of labour, represented by 100° in the pie chart, we can use the unitary method:

75° represents Rs. 112500

⇒ 100° represents =  \frac{112500}{75}  ×  100

                               = Rs. 150000

∴ Cost of labour = Rs. 150000

The table below shows two equations:
VMariaS [17]
| 3x - 1 | + 7 = 2
| 3x - 1 | = 2 - 7
| 3x - 1 | = -5.....no solution because an absolute value cannot equal a negative number.

| 2x + 1 | + 4 = 3
| 2x + 1 | = 3 - 4
|2x + 1 | = -1...same thing...no solution..cannot equal a neg. number

so Eq. 1 and Eq. 2 both have NO SOLUTIONS :)
