Answer:
20%
Step-by-step explanation:
1/5 of 1 hour = 20 minutes
so 1/5 = 20%
25% + 20% = 45%
0.35 = 35%
45% + 35% = 80%
100% - 80% = 20%
Answer = 20%
Hope this helps!
Inequalities are used to show the relationship between unequal expressions.
The inequalities that represent the maximum weights are:
- <em>2 axles - </em>
<em>.</em> - <em>3 axles - </em>
<em>.</em> - <em>4 axles - </em>
<em>.</em>
<em />
Let the maximum weight be represented with x
In inequality, maximum means less than or equal to i.e. 
<u>(a) 2 axles</u>
The maximum weight, here is 40000.
So, the inequality is:

<u>(b) 3 axles</u>
The maximum weight, here is 60000.
So, the inequality is:

<u>(c) 4 axles</u>
The maximum weight, here is 80000.
So, the inequality is:

Answer:
1/2
Step-by-step explanation:
Take any point from the original, like (2,2) If the new point is (1,1) then the change would be 1/2
<span>A relationship between two variables in which one is a constant multiple of the other. The constant here is also called the constant of variation. In order to obtain this value, we manipulate the equation by isolating the variables. We do as follows:
</span><span>2x +6y = 0
y = -x/3
Therefore, the constant of variation is -1/3. Hope this answers the question. Have a nice day.</span>
Answer:

Step-by-step explanation:

Add 25 to both sides:


Square root both sides:
(Since a negative number multiplied by itself gives positive, there are two answers.)
