Answer:
$460.20
Step-by-step explanation:
499*15% = 74.85 (total discount price)
499-74.85 = 424.15 (deduct discount from original price)
424.15*8.5% = 36.05275 (total tax from price)
424.15+36.05275 = 460.20275 (add tax to discounted price)
B) 3.708 x 10^9 is the correct answer
13x - 6y = 2......multiply by 2
3x - 4y = -10....multiply by -3
------------------
26x - 12y = 4 (result of multiplying by 2)
-9x + 12y = 30 (result of multiplying by -3)
-----------------add
17x = 34
x = 34/17
x = 2
now sub 2 in for x into either of the original equations to find y
3x - 4y = -10
3(2) - 4y = -10
6 - 4y = -10
6 + 10 = 4y
16 = 4y
16/4 = y
4 = y
solution is (2,4)

Answer:
B.)
Step-by-step explanation:
In step #1 they did the distributive property
2/5 × 15x = 6x
2/5 × -30y = -12y
The new equation would be:
6x - 12y + 10x
<em><u>Further</u></em><em><u> </u></em><em><u>Explanation</u></em>
They then combined 6x + 10x to get 16x
16x - 12y
They then factored it out to 4(4x - 3y)
