There are 42 children in the classroom each student will get 28 pencils and 46 erasers how many pencils will the teacher have to
Aleksandr-060686 [28]

Since the question is asking how many pencils the teacher will have to give out, we can automatically ignore the 46 erasers from the problem because it is not relevant. The information was most likely put there to confuse you.

Each student is getting 28 pencils, so if we multiply the number of students by 28 pencils, we will find how many pencils the teacher will need to give out.

There are 42 children in the classroom, so multiply 42 by 28.

42 * 28 = 1,176

The teacher will have to give out <u>1,176 pencils</u> to her 42 children in the classroom.

Which of the following graphs shows the solution for the inequality<br> y-4&gt; 2(x+2)?
timofeeve [1]

Answer:

Answer:

Graph C shows the solution for the inequality

Step-by-step explanation:

y - 4 > 2(x + 2)

y > 2x + 4 + 4

y > 2x + 8

Let y = 2x + 8, Then

X-intercept (0, 8)

Y-intercept (-4, 0)

Since the inequality sign is > we use broken line.

Put,  (0, 0)

y > 2x + 8

0 > 0+ 8

0 > 8 Which is false

so, the answer will be above the broken line

Hence , Graph C shows inequality
