Answer:
(14, -2)
Step-by-step explanation:
To solve by using substitution, begin by solving for a variable in the first equation. Let's solve for x:

Now we know what <em>x</em> equals. Let's substitute this into the second equation:

We can then simplify:
Given equation
Combine y terms
Add 2
Divide by -11
So, we now know the value of y = -2.
To find the value of X, we can substitute the value of Y into one of the equations. Let's use the first one:

Substitute for y
Distribute 8
Add 16
So, we now know the value of x = 14.
Therefore, we know a solution to the system of equations is (14, -2).
Answer:
B
Step-by-step explanation:
Adams headed the Commission that negotiated the Treaty of Ghent in 1814, which ended the War of 1812 with Great Britain.
5 is not a divisor of any of the dimensions of the given box, so selections A, C, D can't work.
Each of the dimensions of selection B is a divisor of a different dimension of the box, so ...
.. the correct choice is selection B) 7 × 9 × 12.
It’s 45%. This is because when changing a decimal into a fraction you move the decimal over two times to the right.
