Answer:
picture from Goldbach's conjecture.
Step-by-step explanation:
Goldbach's conjecture is one of the oldest and best-known unsolved problems in number theory and all of mathematics. It states:
Every even integer greater than 2 is the sum of two primes.
The conjecture has been shown to hold for all integers less than 4 × 10^18, but remains unproven despite considerable effort.
So on the red and blue axes you see primes. The list of black numbers are even numbers.
Answer:
he saved $25
Step-by-step explanation:
The answer is 25 because 15 multiplied by 5 is 75 and 5 multiplied by 5 is 25.
Answer:
G
Step-by-step explanation:
difference between coordinates of A and C is 9 because 7-(-2) is 9, one-third of nine is 3, -2+3=1 G is 1. (sorry for poor phrasing)
Since we are given x in terms of y, the most efficient way to solve it would be to substitute in the 
for x in the second equation. So, we then have:
So, now that we have our y, we can find x. We can actually use either equation, top or bottom, to find x, but to be efficient we should use the top one since we have x in terms of y, so:
So, our ordered pair is (2,-6).
Answer:
$830
Step-by-step explanation:
x/2=200+215
x/2=415 multiply by two on both sides to get x alone
x=830
