Answer:
<h2>
y = -4/9</h2>
Step-by-step explanation:
Given the system of equations y = 3/2 x − 6, y = −9/2 x + 21, since both expressions are functions of y, we will equate both of them to find the variable x;
3/2 x − 6 = −9/2 x + 21,
Cross multiplying;
3(2x+21) = -9(2x-6)
6x+63 = -18x+54
collecting the like terms;
6x+18x = 54-63
24x = -9
x = -9/24
x = -3/8
To get the value of y, we will substitute x = -3/8 into any of the given equation. Using the first equation;
y = 3/2x-6
y = 3/{2(-3/8)-6}
y = 3/{(-3/4-6)}
y = 3/{(-3-24)/4}
y = 3/(-27/4)
y = 3 * -4/27
y = -4/9
Hence, the value of y is -4/9
Yes they are entirely contained
Answer:

Step-by-step explanation:
Answer:
$1800
Step-by-step explanation:
You would use proportions. 11.5/100 (11.5%) multiplied by 207/x.
Cross multiply 100 and 207, then divide that answer by 11.5. You should get 1,800 as your answer.
Therefore, the dollar amount of shoes that Maria sold is $1800.
