It will be positive 1/2x and an easy way to find multiplicative inverse is like this 

5x would be 1/5x   -5x would be -1/5x      3x would be 1/3x   -3x would be -1/3x


so 2x would be 1/2x

vovikov84 [41]

The total solution will include 17.5 cup of vinegar 0.5 cups of rubbing alcohol, and 2 cup of water which is a total of 35 cups of solution. Sofie will need 6 total containers to hold all of the solution.

<h3>Number of container</h3>

1 cup of rubbing alcohol:

1 cup of rubbing alcohol=1÷1/2

1 cup of rubbing alcohol=2

Cup of alcohol needed:

Cup of alcohol needed=1+1/2+16

Cup of alcohol needed=17.5 cups

Total cups:

Total cups=17.5×2

Total cups=35 cups

Number of container:

Number of container=1+35/5

Number of container=1+5

Number of container=6  containers

Therefore the total solution will include 17.5 cup of vinegar 0.5 cups of rubbing alcohol, and 2 cup of water which is a total of 35 cups of solution. Sofie will need 6 total containers to hold all of the solution.

An airline charges $150 for a ticket and $20 for each bag.
natta225 [31]

Answer:

The equation shows the relationship between the number of bags, b, and the total cost, c, for flying with this airline is:

C = 20b + 150

Hence, option C is correct.

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

  • m is the rate of change or slope
  • c is the y-intercept

Given that an airline charges $150 for a ticket. It means the initial condition is $150.

Therefore, the y-intercept c = 150.

Given that an airline charges $20 for each bag. It means the rate of change is $20 for each bag.

Therefore, the rate of change or slope m = 20

Let 'C' be the total cost and 'b' be the number of bags.

Thus, substituting y = C, x = b, m = 20 and c = 150

y = mx + c

C = 20b + 150

Therefore, the equation shows the relationship between the number of bags, b, and the total cost, c, for flying with this airline is:

C = 20b + 150

Hence, option C is correct.
