Answer:
option D
D. x = 5, y = 2
Step-by-step explanation:
Given in the question two equation,
Equation 1
5.3x + y = 28.5
Equation 2
4.2x + 3.1y = 27.2
rearrange equation 1 in terms of y
y = 28.5 - 5.3x
Substitute the value of y in equation 2
<h3>4.2x + 3.1(28.5 - 5.3x) = 27.2</h3>
4.2x + 88.35 - 16.43x = 27.2
4.2x - 16.43x = 27.2 - 88.35
-12.23x = -61.15
x = 61.15/12.23
x = 5
put value of x in any of the equation
<h3>5.3(5) + y = 28.5</h3>
y = 28.5 - 26.5
y = 2
(6,2) is the fourth vertex
450 miles
1 in. Per 60 miles
460/60 = 7.5 inches
Based on the commission that Xavier receives from Art Van Furniture, the total value of the furniture sold is $5,500.
<h3>How much furniture did Xavier sell?</h3>
The commission that Xavier earns on his first $1,000 should be removed to be:
= 930 - (12% x 1,000)
= $810
This value of $810 is 18% of the balance of Xavier's sales:
= 810 / 18%
= $4,500
Added to the first $1,000, Xavier's total sales are:
= 4,500 + 1,000
= $5,500
