a + m = 30
a = m - 8
(m - 8) + m = 30
2m - 8 = 30
2m = 30 + 8
2m = 38
m = 38/2
m = 19
a = m - 8
a = 19 - 8
a = 11
so Amy has $11 and Maria has $ 19

<em>In decimal form, a = 114.5; b = 25.5</em>
We will write this as a system of equations, where
and
are the two angles.

We will use substitution to solve this system. We know what
equals, so we plug that into the second equation.

Combine the like terms.

Add
on both sides.

Divide both sides by
.

Now just subtract that from
.

x(x-7)=8
x^2-7x-8=0
(x-8)(x+1)=0
so x=8 (and -1 but width can’t be negative)
So your answer is C. 8

Answer: The answer is 
Step-by-step explanation: Given that Rei is barricading a door to stop a horde of zombies by satcking boxes of books on a table in front of the door.
The weight of each box is 30 kilograms and the weight of the table with 8 boxes on the top is 310 kilograms.
So, if 'g' denotes the weight of the table alone, then we have

Therefore, the weight of the table without boxes is 70 kilograms.
Now, if 'W' is the total weight of the barricade, then it can be written as a function of 'x', the number of boxes Rei stacks on the table. The expression is as follows -

Thus, the required function is
