Answer:
23 maybe
Step-by-step explanation:
Sammy walks 0.125 miles/hour
1 1/4 miles = 2.75 miles
2.75miles ÷ 0.125 miles/hour = 22
It will take Sammy 22 hours to walk 1 1/4 miles.
Answer:
There are 9 distinct possible values for q.
Step-by-step explanation:
Let ab be a positive two-digit integer.
- a×b=q=7k from some positive integer k.
- either a or b is 7, since 7 is a prime number and k can be maximum 9.
- assume a=7, then b can be 1,2,3,4,5,6,7,8,9
- b cannot be 0 because a×b=q has to be positive
- if b=7, then a can be 1,2,3,4,5,6,7,8,9
- in both cases there are 9 distinct values for q, which are 7,14,21,28,35,42,49,56,63
Mult. both sides of this eq'n by 4 will remove the fraction 1/4, a good idea.
Then 20x - 8(x+1) = 1, or 20x - 8x - 8 = 1
Combining the x terms, 12x = 9. Dividing both sides by 12, x = 9/12, or 3/4.
A = false, it is simply not possible
B = false, it is also not possible
C = false, so it is also impossible
Am I missing anything? If not, I guess just don’t circle any of them!
