Hello!
-4x - 10x
When subtracting terms with the same variable degree (x), we can simply subtract the coefficients from each other:
-4 - 10 = -14
We can add on the x variable once we have done this:
-14x. Therefore, B is the correct answer.
Answer:
11
Step-by-step explanation:
just flip the problem around 14+q=25
then do 25-14

Wendy spent four hours on the train.
If the...
Train Speed= 60 mph
Train Time= x
Bus Speed= 40 mph
Bus Time= 5.5-x
Total Time= 5.5 hr
and
Total Distance= 300 miles
Then we can put all of that into the equation...
60x + 40(5.5-x)= 300
Now, following the order of operations we can free the x from the parenthesis by multiplying 40 by 5.5 and (-x) to get...
60x + (-40x) + 220= 300
Next we can simplify by adding the 60x and (-40x) to get...
20x + 220= 300
After that we need to get the x alone on the left side. To do this we must use reverse order; if we subtract 220 from 220 on the left side and then we can subtract 220 from 300 on the left side. Remember the Golden Rule of Algebra! If you add, subtract, multiply, divide, or raise to a power on one side you must do it on the other! This gives us...
20x + 220 - 220= 300 - 220
20x= 80
Now all that is left to get x all alone on the left is to look back at the golden rule of algebra and divide 20 from both 20x and 80. Which gives us...
20x/20 = 80/20
x= 4
And that gives us our answer! 4 hours :D
Hope this helped!
First of all the answer is (6) and don’t click on the link from the other answer :)
