Clara has pennies and quarters in her purse. She counts a total of 28 coins. If the total value of the coins is 76 cents, which system of equations can be used to determine the number of pennies and the number of quarters? Assume p represents the number of pennies and q represents the number of quarters. p + q = 28. p + 25 q = 76.
p + q = 28. 25 p + q = 76.
p + q = 76. p + 25 q = 28.
p + q = 76. 25 p + q = 28.

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

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

70.30
