Emma has 5 3/8 punds of potato salad and 2 7/8 pounds of egg salad for a picnic. how many more pounds of potato salad than egg salad does emma have? a - 3 pounds b- 2 3/4 pounds c - 2 1/2 pounds d - 2 1/4 pounds

The correct answer option is C. pounds

Step-by-step explanation:

We are given that Emma has pounds of potato salad and pounds of egg salad for a picnic.

We are to find out how much more pounds Emma has of potato salad than the egg salad.

To find this, we simple need to subtract the pounds of egg salad from the pounds of potato salad.

pounds

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

(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
