Select the equation that represents the problem. Let x represent the unknown number.
Ms. Evans bought 240 crayons for her class. The crayons
came in packs of 12. How many packs did she buy?
A. x= 12 = 240
B. 240 - x = 12
C. 12x = 240
D. 240x = 12

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110

most likely linear (proportionate)

step-by-step explanation:

as time increases heart rate increases

i'm pretty sure the answer is a. decreases with increase in
