Answer:
by the -16 did you mean to put a + sign or is that a t
Answer:
36
Step-by-step explanation:
a^2 =6^2=36
We have to write a proportion. We put 35 over 60 to show that 35 miles can go in every 60 minutes. Next to it we write another fraction and put 490 over x because we are trying to find how many MINUTES first. we multiply 490 by 60 which is 29400. Now we divide that by 35. we get 840 minutes. Now we convert this into hours by dividing it by 60 because there are 60 minutes in an hour. 840 divided by 60 is 14 hours. The answer is 14 hours.
First group the coefficients together on their side of the equal sign.
-x + 3x = 2x.
Then, since it is a positive number, subtract it from that side and the other side.
On the other side, the x becomes -x.
Add the 6 from the other side to the 8 to make 14.
14 = -x
Divide both sides by -1, to get the answer.
x = -14
