Step-by-step explanation:
The positive number is equal to 7.
Assuming that the number is equal to "x" we have:
By the sum and product method, we have:
All you have to do is multiply those two numbers and whatever u get is ur answer

Answer:
Step-by-step explanation:
Let J = Jerry's age
Let M = Mary's age = 2J
M - 16 = J + 16
Substitute 2J for Mary's age
2J - 16 = J + 16
2J - J - 16 = 16
J = 16 + 16
J = 32
Jerry is 32.
Mary is twice as old as Jerry.
Mary is 2(32) = 64
343 is the answer because 14 tens is 1 hundred and 4 tens
