Write an equation to find the number of students in Mr. Boggs' homeroom if the total number of students is 90.

gladu [14]

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

$\\ \sf\longmapsto f(x)=2x^2-3x+1$

$\\ \sf\longmapsto f(1)=2(1)^2-3(1)+1$

$\\ \sf\longmapsto f(1)=2(1)-3+1$

$\\ \sf\longmapsto f(1)=0$

Now

$\\ \sf\longmapsto f(2)=2(2)^2-3(2)+1$

$\\ \sf\longmapsto f(2)=2(4)-6+1$

$\\ \sf\longmapsto f(2)=8-5$

$\\ \sf\longmapsto f(2)=3$
