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

Answer:
Each $148 = 1 pound.
Step-by-step explanation:
We are given with two equations X + y = k and <span>x - y = k. to find the solution of the </span>system<span> of linear equations, we can use elimination by adding the equations to eliminate y. hence the third equation is 2x= 2k ; x = k, hence y is equal to zero. Answer is C</span>
Answer:
5 times the sum of the digits of the number is 9 less than the number formed by reversing digits. → x = (5y - 9)/4 -- equation (1). Case - 2 : And, 4 times the value of the digits at ones place is equal to half the place value of digit at tens place (10x/2).
