Answer:

this is just a hint

Step-by-step explanation:

the question measures 6.EE.7 because it asks the student to solve a real-world problem by writing an equation of the form px=qpx=qpx=q for a case in which p,qp,qp,q and x are all non-negative rational numbers. In this case the equation includes a division expression and shows the total cost of $13.50\$ 13.50$13.50 divided by 666, the number of spiral notebooks.

vovikov84 [41]

Answer:

The answer is the option D

the minimum number of students will be 19

Step-by-step explanation:

Let

x-------> the minimum number of students

we know that

15x\geq 275 ------> inequality that represent the situation

The domain of the inequality is the interval-------> [0,24]

Solve for x

Divide by 15 both sides

x\geq 275/15\\ x\geq 18.33

so

the minimum number of students will be 19

Find the value of the polynomial 3x<br> 3 – 4x<br> 2+ 7x + 5, when x = 3 and also when<br> x = –3.
babymother [125]

Answer:

71

-133

Step-by-step explanation:

Given the polynomial :

3x³– 4x² + 7x + 5, when x = 3 and also when

x = –3.

Put x = 3

3(3)³– 4(3)² + 7(3) + 5

3(27) - 4(9) + 21 + 5

81 - 36 + 21 + 5

= 71

Put x = - 3

3(-3)³– 4(-3)² + 7(-3) + 5

3(-27) - 4(9) - 21 + 5

-81 - 36 - 21 + 5

= - 133
