Answer:
5^8/5^x=5^6 the asnwer is 2
Answer:

Step-by-step explanation:
<h3>Step 3:</h3>
--------------------(1)
<h3>The next step will be:</h3>
- to find the b² for the expression on the left.
<h3>How to find b²:</h3>
Take the expression

<u>We can also write it as:</u>

According to the formula
, the b of this expression is
. So,
b² will be:

So, we will add
to both sides in Eq. (1)
For STEP 4, the equation will become:

![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
1) old: 4 ; new: 5 = (5-4)/4 = 1/4 = 25% increase
2) old: 1.0 ; new: 1.3 = (1.3 - 1.0)/1.0 = 0.30/1 = 30% increase
3) old: 15 ; new: 12 = (12-15)/15 = 3/15 = 1/5 = 20% decrease
4) old: 30 ; new: 18 = (18-30)/30 = 12/30 = 2/5 = 40% decrease
5) old: 60 ; new: 63 = (63-60)/60 = 3/60 = 1/20 = 5% increase
6) old: 160 ; new: 136 = (136-160)/160 = 24/160 = 12/80 = 3/20 = 15% decrease
7) old: 7.7 ; new: 10.5 = (10.5-7.7)/7.7 = 2.8/7.7 = 36% increase
8) old: 9.6 ; new: 5.9 = (5.9-9.6)/9.6 = 3.7/9.6 = 39% decrease
If the 5 of them weigh 1/4 of a ton
then 1 of them weigh x
5/1 = 1/4//x Do you see what happens? Just by writing down the givens you get a proportion. It will work better for you if you change the 1/4 to 0.25
5/1 = 0.25/x Now it looks like an ordinary proportion. Cross multiply
5x = 0.25*1 divide by 5
x = 0.25/5
x = 0.05 tons. We better change this to pounds.
1 ton = 2000 pounds
0.05 ton = x
1/0.05 = 2000/x Cross multiply
x = 2000 * 0.05
x = 100 pounds.
