Answer:
A D E
Step-by-step explanation:
There are several process for finding the HCF or Highest Common factor for any numbers given. In this case the two numbers given are 240 and 1500.
Firstly we need to divide 1500 by 240 and check if there are any remainders. On dividing we get quotient is 6 and remainder is 60. Now again we have to divide 240 by 60 which we found as remainder previously. Then on dividing 240 by 60 we get no remainder. So the 60 is the HCF or the Highest Common Factor of 240 and 1500. This is the easiest process by which the HCF of any set of numbers can be found.

4x - 5(x + 3) Remove the brackets. Watch the - sign and -5*3
4x - 5x - 15 Combine the xs
-x - 15
Answer:
16/13 is the answer.
26-10 is 16 and 2x5+3 is 13
Answer:
Part A: y = $250 + $45x
Part B: U = y * 0.75 or U = ($250 + $45x) * 0.75
Part C: $390
Step-by-step explanation:
Part A: In this scenario, we have fixed costs for the treatment and two variables, one of which is the number of appointments which is represented by the letter x and the total amount of costs which is represented by the letter y in the following equation...
y = $250 + $45x
Part B: Now we have the equation for the total cost we can update it to add the 25% discount. Since this is a discount it means that it is being subtracted from the 100% original price. Therefore, we need to multiply the total cost by the decimal form of 75% (100 - 25) which we can get by dividing the percentage by 100 like, which gives us 0.75. Now we multiply this value by the total cost in order to get the updated cost (U).
U = y * 0.75 or U = ($250 + $45x) * 0.75
Part C: Now we can substitute the number of appointments variable (x) by 6 and solve for U.
U = ($250 + $45x) * 0.75
U = ($250 + $45(6)) * 0.75
U = ($250 + $270) * 0.75
U = $520 * 0.75
U = $390
