Let x= original savings
(x-1,600) - 2/5 (x-1,600) = 1/3x
(x-1,600) - 2/5 + 640 = 1/3x
(3/5)x - 960 = 1/3x
(3/5)x - (1/3)x = 960
(4/15)x = 960
(15/4)(4/15)x = (15/4) 960
x = 15* 240 (960/4 = 240)
x = $3,600 is his original savings
Check:
$3,600 - 1,600 = 2,000
(2/5)($2,000) = $800
2,000 - 800 = 1,200 left over
Y=20x+50
Y is the total cost and x is the number of hours

<h3><u>Question</u></h3>
<em><u>What are the coordinates of the vertices of the rose garden after a translation two yards east and four yards south?</u></em>
Step-by-step explanation:
<em><u>Answer: The coordinates of the vertices of the original rose garden are A(3, 6), B(3, 3), C(4, 3), and D(4,</u></em>
Answer:
18 and 10.
Step-by-step explanation:
yz - x
= 8*3 - 6
= 24 - 6
= 18
2(x + z) - y
= 2(6 + 3) - 8
= 2 * 9 - 8
= 18 - 8
= 10
