To get the number at the back, you would need to multiply the number in front by 3 and minus 1.
The answer would be A
I think your answer would be C.
One <em>possible answer</em> is:
9×(2+3)
Explanation:
First we find the sum of 18 and 27. 18+27 = 45.
Next we find the GCF of 18 and 27. We do this by finding the prime factorization of each:
18 = 2*9
9 = 3*3
Thus, 18 = 2*3*3.
27 = 3*9
9 = 3*3
Thus, 27 = 3*3*3
We want the common factors; there are 2 3's in common, so 3*3 = 9 is the GCF. This makes the product 9×( ). The missing number would be 5, since 9*5 = 45. Writing this as a sum, we can use 2+3; this gives us 9×(2+3).
Answer:
142.03 would be your answer
Step-by-step explanation:
You can multiply 123.50 by 15, which gets you $1852.50. Divide that by 100 and you are left with $18.525, which you can round to $18.53. Add that to what the cost of the bill was and you are left with $142.03
