Answer:
it would be 90 degrees clocwise
Answer:
79
Step-by-step explanation:
60<xy<100
y -2 =x
if it is prime
y cannot be even
so y could be 1,3,5,7,9
x would then be 9,1,3,5,7
but to be between 60 and 100
x must be 7 or 9
so the number must be 79 or 57
57 is not prime so
the number is 79
20 watches are made since 385 = 15n + 85. 385 - 85 is 300 and 300 divides by 15 is 20.
30%*470=141 (So the number of students in 8 grade is 141)
