19)find a ratio that compares the relative sizes of the quantities. (use the same units of measurement for both quantities. write the ratio as a fraction in simplest form.)
9 weeks to 7 days

The answers to all the questions are given below.

Step-by-step explanation:

8)The ratio of the numbers 27 feet and 54 yard

1 foot = 0.3333 yard

27 feet = 9 yard

Required ratio =  = 0.167

9)A 17 ounce bag costs $5.27.

Hence cost of 1 ounce bag = = $0.31

12)For trip of 240 miles ,it uses 8 gallons.

13)1 quart = 0.25 gallons

Hence the ratio would be

14)1 pound = 0.0005 tonnes.

Hence the ratio would be

19)1 week = 7 days

So the ratio would be

These are the required ratios

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
