It is just a simple proportional problem. If you subtract 10%, then you subtrat 10 kg.
The numbers that are 0.6 unit from 1.3 on the number line are 0.7 and 1.9
<h3>How to determine the
numbers that are 0.6 unit from 1.3 on the
number line?</h3>
The number is given as:
Number = 1.3
The distance is given as:
Distance = 0.6
The numbers that are 0.6 unit from 1.3 on the number line are represented as:
Number = 1.3 ± 0.6
Expand
Number = (1.3 - 0.6, 1.3 + 0.6)
Evaluate
Number = (0.7, 1.9)
Hence, the numbers that are 0.6 unit from 1.3 on the number line are 0.7 and 1.9

Answer:
see below
Step-by-step explanation:
The costs are
2230.80 + .03 b where b is the board foot
the income was 1.13b
Profit is income - costs
Profit = 1.13b - (2230.80 + .03 b)
Distribute
= 1.13b - .03b - 2230.08
= 1.10b - 2230.08
Profit is when the money is greater than 0
(breaking even is 0)
0 <1.10b - 2230.08
Add 2230.08 to each side
2230.08 < 1.10b - 2230.08 + 2230.08
2230.08 < 1.10b
Divide by 1.10
2230.08/1.10 < 1.10b/1.10
2027.345455 <b
They must sell at least 2027.345 board feet of lumber per day to make a profit
You can not work out it unless provided initial distance between the house and shoreline.
The answer would be x= 27
You would take the 30 from the angle and make an equation with the x+3
Steps are:
X+3=30
Subtract 3 from 30 to get you 27
Therefore x= 27
