Answer:
XY = 18
Step-by-step explanation:
The figures are similar so the ratios of corresponding sides are equal, that is
= , substitute values

Answer:
In 9 days will the second warehouse have 1.5 times more coal than the first one
Step-by-step explanation:
The coal left in warehouses after x days can be found using the equation:
- first warehouse: 185 - 15x
- second warehouse= 237-18x
Let the second warehouse have 1.5 times more coal than the first one after n days then
- 1.5 ×(185 - 15n)=237-18n which gives:
- 277,5-22,5n=237-18n and
- 40,5=4,5n
- 9=n
