Answer:
80 / 5 = <u>40</u> / 5 + <u>40</u> / 5 = <u>10</u> + 6 = <u>16</u>
Step-by-step explanation:
80 / 5 = 16
__ / 5 + __ / 5
You can do 80 / 2 to fill in those two blanks because the answer needs to equal the same as 80 / 5
80 / 2 = 40
40 / 5 + 40 / 5
8 + 8 = 16
the third blank needs to also equal 16. So you can do 16 - 6 to know what fills in the blank.
16-6
10
10+6 = 16
The last blank must equal the same as all the other equations so 16 would fill it.

Answer:
Step-by-step explanation:
Let x and y are the two positive real numbers
product of two numbers is 21
The sum of the two numbers is f(x) =x+y
Replace y with 21/x
we need to find smallest possible sum , so we take derivative using power rule
when sum is minimum then the derivative is equal to 0
multiply both sides by x^2
Take square root on both sides
Answer:
3(x+6)=3x+18 = infinite
x-7=-7+x = infinite
5(x-3)=15+5x = no solution
