310 / 75-5 = 4.42 or 4.4 hours. Let me know if you have any other questions.
Answer:
x = 6
Step-by-step explanation:
Alternate angles are congruent.
7x - 9 = 3x + 15 {Subtract 3x form both sides}
7x - 3x -9 = 15
4x - 9=15 {Add 9 to both sides}
4x = 15+9
4x = 24
x = 24/4
x = 6
1/5 of 200 is 40 which mean she gave 40 away and she has a 160 left
For this case, we have the following expression:

We simplify the expression:
If we add similar terms, taking into account that different signs are subtracted and the sign of the greater one is placed, we have that 
So, we have to:

Answer:
-3x + x + 5 = -2x + 5
<em>Question:</em>
<em>Abraham has visited at least 50 countries; he plans to visit five new countries per year (Y) for the next several years. Which inequality and solution shows the amount of years they will take for Abraham to meet his goal.</em>
Answer:


Step-by-step explanation:
Given
------ at least

Required
Represent as an inequality
"at least" means 
So the countries he has visited can be represented as thus;

If
1 year = 5 countries
y years would be 5y countries
So, in y years; he'd have visited

To determine the value of y.
We have that
<em>in the world</em>
<em>Substitute 195 for Countries</em>

<em>Collect Like Terms</em>


<em>Divide through by 5</em>


<em>Reorder</em>

This means that; he'll visit all countries in at most 29 years' time
