Answer:

1/2

Step-by-step explanation:

Since we're dealing with fractions, the total fraction is 1

Mortgage =1/3

Food =1/6

Fraction of income left=x

So we equate everything above to 1

\frac{1}{3}  +  \frac{1}{6}  + x = 1

\frac{1}{3}  +  \frac{1}{6}  + x =  1  \\  lcm = 6  \\ multiply \: each \: term \: by \: 6 \\ 6 \times  \frac{1}{3}  + 6 \times  \frac{1}{6}  + 6(x) = 6(1)

=  > 2(1) + 1(1) + 6x = 6 \\ 2 + 1 + 6x = 6 \\ 3 + 6x = 6

6x = 6 - 3 \\ 6x = 3 \\ x =  \frac{3}{6}  =  \frac{1}{2}

Goby fish and shrimp naturally live close together. A pet store is selling bags
Blababa [14]

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.
