<h2>-10x - 20y</h2>
Step-by-step explanation:
18% because 20+3=23 and 134-3=131 and so you divide 23/131 and you get 17.55 which rounds up to 18%
<span> 6 over x minus 4 equals 4 over x
6/(x-4) = 4/x
4(x-4) = 6x
4x - 16 = 6x
2x = -16
x = -8
</span>Verify:
6/(-8-4) = 4/-8
6/(-12) = 4/(-8)
-1/2 = -1/2
<span>
answer
</span><span>B) x = −8, non-extraneous</span>
6 large + 5 small = 127 kg ------------ (1)
2 large + 3 small = 51kg ------------ (2)
<u>(2) x 3 :</u>
6 large + 9 small = 153 ---------------- (2a)
<u>(2a) - (1) :</u>
4 small = 26
1 small = 6.5kg ------------ (sub into equation 1)
6 large + 5 small = 127 kg
6 large + 5(6.5) = 127
6 large + 32.5 = 127
6 large = 127 - 32.5
6 large = 94.5
1 large = 15.75 kg
Answer: The small box weighs 6.5kg and the big box weighs 15.75 kg
