Answer:
49
Step-by-step explanation:
the number is "ab" (2 digits).
ab - 10 = 3×(a+b)
a number is actually the sum of multiplying the digits with their associated powers of 10.
a×10 + b - 10 = 3a + 3b
7a - 2b = 10
b-1 = 2×a
b = 2a + 1
7a - 2×(2a+1) = 10
7a - 4a - 2 = 10
3a = 12
a = 4
b = 2×4 + 1 = 9

Hey there! :) How are you? Basically what you said is right.
Question 1: There are 16 oz (ounces) in a pound, so we do 64/16= 4 lbs (pounds).
Question 2: If Jack has 3 pounds of pasta, that would mean he has 48 ounces, since 1 pound is 16 oz, so 16*3= 48 ounces.
Hoped I helped! Have a nice day, and keep smiling! :)
