A collection of 77 quarters and dimes is worth $12.50. How many quarters are in the collection? PLS HELP ILL GIVE YOU BRAINLEST
mrs_skeptik [129]

Answer:

32

Step-by-step explanation:

77 quarters and dimes

q + d = 77

subtract q from both sides

d = 77 - q

---------------------------

A collection of  quarters and dimes is worth $12.50 (1250 cents)

25q + 10d = 1250

substitute for d

25q + 10(77 - q) = 1250

distribute

25q + 770 - 10q = 1250

Combine like terms

15q + 770 = 1250

subtract 770 from both sides

15q = 480

divide both sides by 15

q = 32

Solve the following system : -x + 5y = 8 and 3x + 7y = -2
poizon [28]

-x + 5y = 8

multiply this equation by 3

-3x + 15y = 24

now add it to the other equation  ( elimination)

-3x + 15y = 24

3x + 7y = -2

-----------------------

0x  + 22 y = 22

divide each side by 22

y =1


substitute into -x + 5y =8  to find x

-x + 5(1) = 8

-x + 5 = 8

-x =3

divide by -1

x =-3

Answer (-3,1)

Choice A
