Mathematics

ser-zykov [4K]3 years ago

Answer:

Step-by-step explanation:

You;ll run into this formula a lot. Make sure you study it carefully.

A = 25

a = 5

d = 13

Find n

25 = 5 + 13*(n- 1)

20 = 13(n - 1)

This isn't going to work out. 20/13 does not give a whole number which it should.

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
