julsineya [31]

Answer:

b.) 18(m+2m)

d.) 18m+18(2m)

e.) 54m

Step-by-step explanation:

Given;

total number of Mr Moretti's students = 18

number of mechanical pencils for each student = m

total number of mechanical pencils for all the students = 18m

number of regular pencils for each student = 2m

total number of regular pencils for all the students = 18(2m)

The total number of pencils given to all the 18 students by  Mr Moretti is given by;

T = Total mechanical pencils + total regular pencil

T = 18m + 18(2m)

T = 18(m + 2m)

T = 18(3m)

T = 54m

Therefore, based on the expressions above, the correct options include;

b.) 18(m+2m)

d.) 18m+18(2m)

e.) 54m

natita [175]

Answer:

x = 52.00

Step-by-step explanation:

Given

Demand: p = 0.16x + 16

Supply: p -0.09x + 29

Required

Determine the equilibrium price

This is determined when Demand = Supply

So:

0.16x + 16 = -0.09x + 29

Collect Like Terms

0.16x + 0.09x = 29 - 16

0.25x = 13

Solve for x

x = 13/0.25

x = 52.00

<em>Hence; The equilibrium price is when x = 52.00</em>

Which best describes the relationship between the line that passes through the points (–6, –1) and (–11, 1) and the line that pa
yaroslaw [1]
The two are perpendicular to each other because the two slopes are negative reciprocals

(Y2 - Y1) / (X2 - X1)

First slope:
( 1 - (-1)) / (-11 - (-6))
2/-5

Second slope:
(-13 - (-8)) / (-5 - (-3))
-5/-2 or 5/2

You know when two aliens are perpendicular when you multiply the two slopes and get -1 as the product

-2/5 X 5/2 = -1

Thus the two lines are perpendicular to each other.

Answer:  84

<u>Step-by-step explanation:</u>

Set up a proportion as follows: \dfrac{\text{students that practice everyday}}{\text{total students}}

\dfrac{7}{12}=\dfrac{x}{144}

Cross multiply: 12x = 7 × 144

Divide by 12:         x = 7 × 12

Simplify:                x = 84
