N^(7-3) = n^4
When dividing indices, you subtract the indices. If we multiply, you add them.
5 less (-5) than 1/3 of number (n/3) is (=) 2 more than (2+) half of the number (n/2)
-5+n/3=2+n/2
add 5 to both sides
n/3=n/2+7
times 6 both sides
2n=3n+42
minus 2n both sides
0=n+42
minus 42 boh sides
-42=n
the number is -42
the number is 18
6, 7
subtract 4r from both sides
-r <-6
divide -1 on both sides, switch the inequality sign
r greater than or equal to 6
Answer:
Step-by-step explanation:
Given
Three and one-half yards of fabric i.e. 
yards
and five and one-half yards of fabric is 
yards
Difference between five and one-half yards and Three and one-half yards is
=2 yards which is positive
Thus it clear that
