Answer:
Because we know the height of the mailbox is 4 feet and the length is 6 feet, and we also know that it's located 54 feet from the base of the flagpole, we can use proportions to solve the problem.
= 
Cross-multiply 4 with 54 and 6 with x to result with 216=6x. Divide 6 to both sides to get 36. So, the height of the flagpole would be 36 feet.
Answer:
yes it is a function it passes the vertical line test
A tire that is 1.4691 cm in diameter will work because it is less than the maximum diameter.
Answer:
How Am i supposed to know
Step-by-step explanation:
Let x and y be the two numbers
Saying "The sum of two numbers is 27" means x+y = 27. The term "sum" is the result of adding. So the first equation is x+y = 27
The second equation is y = x+3 where we assume that y is the larger number of the pair.
So your system of equations will be
x+y = 27
y = x+3
Use substitution to solve this system.
x+y = 27
x+( y ) = 27
x + (x+3) = 27 ... notice how y has been replaced with x+3 (since y = x+3)
x+x+3 = 27
Solve for x and then use this to find y. I'll let you finish up.
