An integer has to be either even or odd
Even numbers are numbers divisible by 2, while odd numbers are not
Let us represent the 2 even numbers like this
ax+1
bx+1
When you add the two numbers together, you get
2a + 1 + 2b + 1
This can be simplified using the inverse of distributive property
2(a+b) + 2
2(a+b+1)
This is the sum, which is divisible by 2
Hello!
You first have to look and see if there is an outlier
An outlier is something that is away from the rest of the data
All the numbers are with 1 from each other so there is no outliers
The answer is the first one
Hope this helps!
The second one and the fourth one.
Step-by-step explanation:
As the problem states, it takes 166.5 gallons of water in 3 mins. Since it states it is a proportional relationship, we know that 166.5/3 is the number of gallons pumped in 1 minute. We can write this as g(the number of gallons) = 166.5/3 * m(the number of minutes) ! In additon, 166.5/3 is equivalent to 55.5, which gives us the second and the fourth equation correct!
Answer:

Step-by-step explanation:
To find the scale, we write a ratio of
and simplify.
We know
.
We simplify to 
We have y = -2 - 2x ;
Then, x + ( -2 - 2x ) = 5 ;
x - 2 - 2x = 5;
- x - 2 = 5 ;
-x = 7 ;
x = - 7;
Finally, y = - 2 - 2 × ( - 7 ) ;
y = - 2 + 14 ;
y = 12;
<span>The x coordinate of the solution to the system is - 7 .</span>
