Hey there!
To find the discount, just multiply the original price by the percent.
49*.65= 31.85(how much it was taken off)
Now subtract31.85 from 49 and you'll get
17.15
$17.15 is now the new price
Answer: 31.3x33

Did the test :)
Answer:
12.8 m.
Step-by-step explanation:
The length of the wire on the shorter pole (AC)
= √(6^2+8^2)
= √100
= 10 m.
The 2 triangles are similar so
10/16 = 8/x where x is height of taller pole.
10x = 128
x = 12.8m
(b/2)^2=(−5)^2
x^2−10x+(−5)^2=<span>24+<span>(−5)^<span>2
</span></span></span><span><span>x^2−10x+25</span>=49
</span><span><span>(x−5)^</span>2</span>=<span>49 (square root)
</span><span>(<span>x<span>−5</span></span>)</span>=<span>±<span>7
x-5=7 => x=12
x-5=-7 => x=-2</span></span>
Answer:
x = -2.5
Step-by-step explanation:
→ Multiply both sides of the equation by the opposing denominator
8x = -20
→ Divide both sides by 8 to isolate x
x = 
or -2.5
