x > 50
2x + 3y > 500
Bracelet is represented by x.
Earrings is represented by y.
Since x > 50 let us assume that x = 50 to get the value of y in the inequality equation.
2x + 3y > 500
2(50) + 3y > 500
100 + 3y > 500
-100 -100
3y > 400
÷3 ÷3
y > 133 1/3
x > 50 ; y > 133 1/3
Let us assume that no bracelet was sold. x = 0 ; y =?
2x + 3y > 500
2(0) + 3y > 500
0 + 3y > 500
÷ 3 ÷3
y > 166 2/3
Let us assume that no earrings was sold; y = 0 ; x = ?
2x + 3y > 500
2x + 3(0) > 500
2x + 0 > 500
2x > 500
÷2 ÷2
x > 250
Let us assume that we sold have of each item.
x = 250/2 = 125 ; y = 166 2/3 ÷ 2 = 100
2x + 3y > 500
2(125) + 3(100) > 500
250 + 300 > 500
550 > 500
To get at least $500, Sarah needs to sell at least 100 bracelets and 100 earrings.
the first one is region 2 and the second is region 3 i think

In order to solve the equation (6.4)x = 32 divided by 6.4 on both sides option (B) is correct.
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have an equation in one variable:
(6.4)x = 32
Divide by 6.4 on both sides in order to find the value of x:
[(6.4)x]/6.4 = 32/6.4
x = 5
Thus, in order to solve the equation (6.4)x = 32 divided by 6.4 on both sides option (B) is correct.
