Answer:
1. c 2. a 3. b
Step-by-step explanation:
The best way to prove these results are the right ones is by multiplying diagonally :
1. 1/3 = 4/12 -----> 1 . 12 = 12 ; 3 . 4 =12
2. 1/2 = 3/6 ------> 1 . 6 = 6 ; 2 . 3 = 6
3. 2/5 = 6/15 -----> 2 . 15 = 30 ; 5 . 6 = 30
The results of the multiplications must be the same if the fractions are equivalent.

Answer:
$2,487.00
Step-by-step explanation:
27x53= 1431
33x32= 1056
1056 + 1431= 2487
Mike age is 3 less then twice the age of his brother nuke.
M = Mike's age now
N = Nuke's age now
M = 2N - 3
Ten years ago, four times nuke's age was one more mike's age.
M-10 = Mike's age 10 years ago
N-10 = Muke's age 10 years ago
4(N - 10) = 1 + M -10
what are their present ages
find M and N
substitute M = 2N - 3 into 4(N - 10) = 1 + M -10:
4(N - 10) = 1 + [2N - 3] - 10
4N - 40 = 2N - 12
2N = 28
N = 14
M = 2(14) - 3 = 28 - 3 = 25
Mike is 25 and Nuke is 14.
check:
4(14 - 10) = 4(4) = 16 = 26 -10 = 1 + 25 - 10
