Answer:

x = 2

Step-by-step explanation:

18 = 6(5 - x) \\ 18 = 30 - 6x \\ 6x - 30 =  - 18 \\ 6x = 30 - 18 \\ 6x = 12 \\  \\ x =  \frac{12}{6}  \\  \\ x = 2

7. how many tiles measuring
Margaret [11]

Answer:

245 tiles

Step-by-step explanation:

1 meter = 100 cm

Area of bathroom = 3.5m x 2.8m = 350x280 = 9800 cm²

Area of each tile = 20cm x 20cm = 400 cm²

Total number of tiles required = 9800/400 = 245

<u>Note</u>

Strictly speaking we have to find out how many tiles can be fitted in the length and breadth of the bathroom. Since the bathroom is 350 cm wide, we can fit 350/20cm = 17.5 tiles. However, there is no concept of 1/2 tile so the question has an ambiguity. along the width, we can fit 280/10 = 14 tiles

17.5 x 14 = 245 but if the question is reworded to how many tiles do we need to purchase to floor the bathroom it would be 18 x 14 = 252

Harry has a part-time job as a babysitter. The table below shows the amount of money Harry earned for different numbers of hours
Dimas [21]

Answer:

Part A- The 1st box is 96 and the second box is 10.

PartB-

Part C-

Step-by-step explanation:

<h2><u><em>Part A:</em></u></h2>

5x12=60

6x12=72

8x12=96

10x12=120

So the 1st box is 96 and the second box is 10.

<h2><u><em>Part B:</em></u></h2>

5     $50

6     $60

8     $80

I know this because Harry receives $10 per hour so you have to multiply the number of hours by $10.

<h2><em><u>Part C:</u></em></h2>

If Harry babysits for 5 hours, he would receive $60 but if he does yard work for 5 hours, he would receive $50. Harry would receive $10 more by babysitting than by doing yard work.

Hoped this helped.
