Write an equation to find the number of students in Mr. Boggs' homeroom if the total number of students is 90.
Teacher: Number of students
Mr. Boggs b
Mr. Hamilton 15(b+2)
Ms. Simpson 15
Mrs. Walton 2b-9

Answers

Answer:

15(b+2) + 15 + 2b-9 +b = 90

Step-by-step explanation:

Essentially you add up all of the values and make it equal to 90, then solve for b

15(b+2) + 15 + 2b-9 +b = 90

15b + 30 + 15 + 2b - 9 + b = 90  

18b + 30 + 15 - 9 = 90

18b + 36 = 90

18b = 54

b=3

Noah could flip the triangle around

Find the midpoint of the line segment with end coordinates of: (−3,−1)and (−4,2) Give coordinates as decimals where appropriate.

Answers

Answer:

ANSWER

M=(−72,12).

Step-by-step explanation:

The midpoint for two points P=(x1,y1) and Q=(x2,y2) is

M=(x1+x22,y1+y22).

We have that x1=−3, y1=−1, x2=−4, y2=2.

So, M=(−3+(−4)2,−1+(2)2)=(−72,12)

Answer:

The answer is

( - 3.5 , 0.5)

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(−3,−1) and (−4,2)

The midpoint is

[tex]M = ( \frac{ - 3 - 4}{2} \: , \: \frac{ - 1 + 2}{2} ) \\ = ( - \frac{7}{2} \: , \: \frac{1}{2} )[/tex]

We have the final answer as

( - 3.5 , 0.5)

it is not a function because there are two different packages available for $180.

That’s not a function because function all have different values, if two things have the same value, it cannot be a function. Two DIFFERENT packages are available for $180, that means it not a function.

The product of [tex]2\frac{5}{8}[/tex] and [tex]- 2\frac{3}{5}[/tex] is [tex]- 3 \frac{27}{40}[/tex]. Options incorrect.  

1, Converting the mixed numbers to improper fractions.

[tex]2\frac{5}{8}[/tex] can be written as [tex]\frac{2*8 + 5}{8}[/tex] = [tex]\frac{21}{8}[/tex].

[tex]- 2\frac{3}{5}[/tex] can be written as [tex]\frac{-2*5 + 3}{5}[/tex] = [tex]-\frac{7}{5}[/tex].

2, Multiplying the two fractions.

[tex]\frac{21}{8} * -\frac{7}{5}[/tex] =  [tex]- \frac{147}{40}[/tex]

3. Expressing the result as a mixed number.

To express  [tex]- \frac{147}{40}[/tex] as a mixed number, divide the numerator by the denominator:

-147 ÷ 40 = -3 with a remainder of -27.

So, the final answer is:

[tex]- 3 \frac{27}{40}[/tex].

Therefore, the product of [tex]2\frac{5}{8}[/tex] and [tex]- 2\frac{3}{5}[/tex] is [tex]- 3 \frac{27}{40}[/tex].

In this calculation, we used the concept of converting mixed numbers to improper fractions, multiplying fractions, and simplifying the resulting fraction.
