Answer:
See below
Step-by-step explanation:
The difference of 5 and 2
5-2 <===== now multply it by 6
6 x (5-2)

so.. the left-hand-side does indeed simplify to x+7, so the equation does check out.
however, notice something, for the equation of x+7, when x = 6, we get (6) + 7 which is 13.
BUT for the rational, we get

so, even though the siimplification is correct, the rational or original expression is constrained in its domain.
Answer:
v = -5, t = -13. , d = -12
Step-by-step explanation:
29) 3v - 9v = 30
Simplifying gives us -6v = 30. Then dividing both sides by -6 reaches our answer of v = -5.
30)12t - 8t = -52
Simplifying gives us 4t = -52. We can divide both sides by 4 to reach a conclusion that t = -13.
31) -8d - 5d + 7d = 72
Simplifying gives us -6d = 72. We can then divide both sides by -6. In doing so, we can achieve our answer that d = -12.
How many students would there be? did not see that information if that is the question but if not I say go with the bus that has more seats yes it is more expensive but more space is better!
Answer:
2.25 square inches
Step-by-step explanation:
we know that
The scale is 
That means
1 inch on a map represent 20 miles in the city
