Answer:
dresses
Step-by-step explanation:
We are given that
Lucy sews dress in 3/4 hours= of dress
Lucy sews at constant rate.
We have to find the number of dresses sewed by Lucy in hour.
To find number of dress sewed by Lucy in 1 hour we will use unitary method.
By using unitary method
Lucy sews in 3/4 hours= dress
Lucy sews in 1 hour=
Lucy sews in 1 hour=
Lucy sews in 1 hour= dresses
Hence, Lucy sews dresses in 1 hour.
Answer:
x =
Step-by-step explanation:
collect the fractional terms on the left side of the equation and other terms on the right side
subtract from both sides
-
+ p = q
subtract p from both sides
-
= q - p
We require the fractions to have a common denominator of mn
multiply the numerator/denominator of the first fraction by n and the numerator/denominator of the second fraction by m
-
= q - p
distribute and simplify the numerators of the fractions
= q - p
= q - p
factor out x from each term on the numerator
= q - p
multiply both sides by mn
x(n - m) = mn(q - p)
divide both sides by (n - m)
x = → n ≠ m
