1) 4/(1/5)
=4 ÷ 1/5
to divide fractions, multiply by the reciprocal/inverse of 1/5
=4 * 5/1
=20
4) (7/9)/7
=7/9 ÷ 7
to divide fractions, multiply by the reciprocal/inverse of 7
=7/9 * 1/7
multiply numerators; multiply denominators
=(7*1)/(9*7)
=7/63
simplify by 7
=1/9
7) (9/10)/6
= 9/10 ÷ 6
to divide fractions, multiply by the reciprocal/inverse of 6
= 9/10 * 1/6
multiply numerators; multiply denominators
= (9*1)/(10*6)
= 9/60
simplify by 3
= 3/20
ANSWER: 1) 20; 4) 1/9; 7) 3/20

Answer:
No graph so we'll use the quadratic formula
x^2+x-4=0
a = 1
b = 1
c = -4
x = -1 +- sqr root (1^2 - 4 * 1 * -4) / 2
x = (-1 +- sqr root (1 +16) ) / 2
x1 = (-1 + sqr root (17)) / 2
x2 = (-1 - sqr root (17)) / 2

Answer:
The expression represents the total cost of the bag which contain x number of goby and x number of shrimp.
Step-by-step explanation:
Each goby fish costs $15 and each shrimp costs $10.
Each bag has an equal number of goby fish and shrimp.
So. let each bag has x number of goby and x number of shrimp
so, the cost of the bag = 15x + 10x
Take x as a common
so, the total cost = x (15+ 10)
so, the expression represents the total cost of the bag which contain x number of goby and x number of shrimp.
Answer:
3.50$
Step-by-step explanation:
Since a nickel is 5 cents, you would do 5 x 60 which would equal 300, which is 3 dollars.
Since a penny is worth 1 cent, you would do 1 x 50 and get 50 cents, which is half a dollar.
3 + .5 = 3.50
