Consider, please, this solution/explanation:
1. suppose, that number of cars is 'x', numbers of buses is 'y'.
2. according to the condition 'a total of 32', it means that x+y=32. This is the 1st equation.
3. according to the condition in one car are 3x persons, in one bus are 27y persons, and totaly 3x+27y=408 people. This is the 2d equation.
4. if to solve the system of two equations:

Answer: 13 - b., 19 - c.
Answer:
It becomes 30
Step-by-step explanation:
When you double a number, it’s increases to two of itself .
So double of 15 means 15 x 2
= 30
Hi there!
The answer is A. The constant 900 represents the amount Kayla's bakery earns in a particular month when there are no online orders.
Since 900 is part of the cost that is added to the amount of money Kayla makes per online order (x), it must represent the amount Kayla's bakery makes without online orders.
Hope this helps!
Answer:
12
Step-by-step explanation:
The least common multiple of {6,8,12} is 24. This can be intuitively figured by noting that any multiple of 12 is a multiple of 6 and that 12 is 1.5x larger than 8. That means we only have so multiple 12 by 2 and 8 by 3 for them to be equal. The GCF of {20,42,72} is 2 as the prime factorization of 20 is 2x2x5 and 42 is 2x3x7. That means even without having to check 72 (which is clearly even so 2 is a factor), we know that 2 is the greatest common factor that they could share. So X/Y = 24/2 = 12
