What is the equation 7n + 6n -5 = 4n + 4
2 answers:
7n + 6n -5 = 4n + 4
combine like terms
13n-5 = 4n+4
subtract 4n from each side
9n -5 = 4
add 5 to each side
9n = 9
divide by 9
n =1
Hi there!
So you need to put all the same terms together so that your equation can be simplified :
7n + 6n -5 = 4n + 4
7n + 6n = 13n
13n - 5 = 4n + 4
Subtract 4n from each side of the equation
9n -5 = 4
Add 5 on each side of the equation
9n = 9
Divide each side of the equation by 9
n = 1
There you go! I really hope this helped, if there's anything just let me know! :)

700. To find out what number a value is ten times as much as, divide by 10.
We use the formule: t=S/v. So:
+ t1= 160/100 = 8/5 hrs = 5760''
+ t2= 160/90 = 16/9 hrs = 6400''
=> t2-t1= 6400 - 5760 = 640'' = 10'40''
Answer:

C
Use the formula of the Pythagorean theorem. a^2 + b^2 = c^2
a = 11.5
b = 18
11.5^2 + 18^2 = 456.25^2
Sqrt(456.25) to find c
c=21.36 in.
