We can solve this by setting up a proportion:

12 seeing the play/ 72 students = 210 seeing the play/ x students

We can cross multiply to solve for x:

(12)x=(72)(210)
12x=15,120
x=1,260 students who attend the school

A grocery store clerk put only packages of flour tortillas and packages of corn tortillas on a shelf. The ratio of the number of
Mazyrski [523]

Answer:

9

Step-by-step explanation:

Let corn tortillas be represented by c, flour tortillas be represented by f and the total number of packages be t

such that

t = c + f     .... eq 1

ratio of c to t = 7 : 16 = 7/16

Therefore, t = 16,    c = 7

substitute the value of t in eq 1

16 =  7 + f

f = 16 - 7

f = 9

1. What is an equation of a line, in point-slope form, that passes through (1,-7) and has a slope of -2/3?
Nookie1986 [14]

1. What is an equation of a line, in point-slope form, that passes through (1,-7) and has a slope of -2/3?


Point Slope form y − y1 = m(x − x1)


Y1: -7 x1:1 slope :-2/3


Y-(-7)=-2/3(x-1)

Y+7=-2/3(x-1)


2. What is the equation of a line, in point-slope form, that passes through (-2,-6) and had a slope of 1/3?


Y-(-6)=1/3(x-(-2))


Y+6=1/3(x+2)



3.What is an equation in point-slope form of the line that passes through the points (4,5) and (-3,-1)


SlopeM: =change in y/change in x

M= -1-5/-3-4

M= -6/-7

M=6/7


So now slope:6/7, point (4,5)

Y-y1=m(x-x1)

Equation in point slope

Y-5=6/7(x-4)
