Answer:
28
Step-by-step explanation:
It can be a one digit no.
_
2C1 = 2 (only two even options available)
It can be a 2 digit no.
_ _
The last digit has to be even for the no. to be even.
2C1 × 4C1 = 8 (2C1 for the last digit, 4C1 for the first)
It can be a 3 digit no.
_ _ _
First digit has to be less than 5 to be less than 500, and the last digit has to be even.
1) 2/4 _ 4
2C1 × 3C1 = 6 (2C1 to choose between 2 and 4, 3C1 for the second digit)
2) 1/3 _ 2/4
2C1 × 3C1 × 2C1 = 12 (2C1 to choose between 1 and 3, 3C1 for the second digit, 2C1 to choose between 2 and 4)
Total = 2 + 8 + (6 + 12)
= 28
Answer:
Part A. It will take him 7 months
Part B. The equation is 30 - 45x + 250
Step-by-step explanation:
Part A. the answer is 7 because in 6 months Matthew will have $225 and if you add 30 you get $255.
Part B. It's the answer because its the only one that makes sense. 250 = 450 + 30. Its 45 not 450. 250 = 30.2 + 45. It's 30 not 30.2 and 30 30 well 30 30 doesn't make sense either.
