A cryptarithm is a math puzzle in which the digits in a simple equation are replaced with letters. Each digit is represented by only one letter, and each letter represents a different digit. So, for example, we might represent 51+50 = 101 as AB + AC = BCB. In the cryptarithm} SEND + MORE = MONEY, what digit does the letter Y represent?

y=2

Step-by-step explanation:

SEND + MORE = MONEY

notice that send and more have 4 digit ( means the number in thousands ,but the answer is 5 digit  means it is in 10000)

first word : 1000S+100E+10N+1 D

second word: 1000 M +100 O+10 R+1 E

the 10000M+1000O+100N+10E+Y

if the answer is the sum of first word+second word:

(S E N D M O R E Y)

M in word Money can not be zero the range is [1,9]

S also can not be zero

  S   E    N    D    s=9 since E can not equal N it has to be 1+E=N

  9   5     6     7

+

  M   O   R     E     m=1 , then o =0

   1    0    8    5  

M   O    N    E  Y

1     0    6    5   2      

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

answer:

c) the x-coordinate of the center of the circle increases by 3
