The perimeter of a rectangular garden is 43.8 feet. It's length is 12.4 feet. What is its width?

9.5
If you add 12.4 plus 12.4 you get 24.8 then you do 43.8 minus 24.8 and you get 19 and 19 divided by 2 is 9.5
9.5+9.5+12.4+12.4=43.8

67. The Goldbach Conjecture. Recall that a prime number is a
Korvikt [17]

Answer:

<u>Test the conjecture for 10 even numbers</u>

10 = 3 + 7

12 = 5 + 7

14 = 7 + 7

16 = 5 + 11

18 = 5 + 13

20 = 7 + 13

22 = 11 + 11

24 = 11 + 13

26 = 13 + 13

28 = 11 + 17

<u>Do you think the conjecture is true? Why or why not?</u>

I believe the conjecture is true because the sum of two odd numbers is an even number and you can find two prime odd numbers for every even number whose sum is that even number.

Must m in the equation y=mx+b always be a positive number?
Effectus [21]

If the slope of the number is positive (the graph goes upward from left to right), then m will be positive, but if the slope is negative (the graph goes downward from left to right), then m is negative. So, no. M does not have to be a positive number, it may also be negative.
