Answer:
x=8
Step-by-step explanation:
x^2 - 48 = 2x
x^2 - 2x - 48=0
(x+6)(x-8)=0
x+6=0 x-8=0
x= - 6 x=8
can not be negative so the answer is x=8

Answer:
Step-by-step explanation:
The 20% discount amounted to ...
0.20 × $42.00 = $8.40
so the price before tax was ...
$42.00 -8.40 = $33.60
The tax amount is 3% of this value, so is ...
0.03 × $33.60 = $1.008 ≈ $1.01
So the total price paid for the shirt was ...
$33.60 +1.01 = $34.61
Randy paid $34.61 for the shirt after discount and tax.
___
<em>Alternate solution</em>
You can realize that the 20% discount means that Randy will pay 80% of the original price of the shirt. Similarly, the 3% added tax means Randy will finally pay 103% of the discounted price. Then the total price Randy pays is ...
$42.00×0.80×1.03 = $34.608 ≈ $34.61
Answer:
y= 1.6
You make 2 a decimal by adding .0 at the end (2.0). Then you subtract 0.4 by 2.0 which equals 1.6.
