Emma and Noah are working on the following problem. Write and solve a situation that uses the expression 30% of 120. This is the situation Emma Wrote: There are a total of 120 books on Miss. Smith's bookshelf. If I have read 30% of them, how many books have I read? The answer is 36 books. This is the situation Noah Wrote: All of the sixth graders were asked who their favorite teacher was. Thirty percent of them answered Mr. Nelson. If that means 120 students said that Mr. Nelson is their favorite teacher, how many total sixth graders are there? The answer is 400 total sixth graders. Who is correct?

(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

answer: i think it is c

your correct answer is c. he organized a political resistance group based on islam.

im sorry for the poor quality answer.

48+y= ?

the y is the variable and the ? could also be a variable
