Answer:
3 =n
Step-by-step explanation:
-3 +3(n+8)= 2(1 + 6n) - 8
Distribute
-3 +3n +24 = 2 +12n -8
Combine like terms
21+3n = 12n -6
Subtract 3n from each side
21+3n-3n = 12n-3n -6
21 = 9n -6
Add 6 to each side
21+6 = 9n-6+6
27 = 9n
Divide each side by 9
27/9 = 9n/9
27/9 =n
Divide the top and bottom by 3
3 =n
Oof I’m not quite sure how to do that
Answer:
To know how much he bought it for, let's consider the actual amount it be x.
Step-by-step explanation:
10% of x + $585 = x
x/10 + $585 = x
$585 = x-x/10
$585= 9x/10
9x=$5850
x=$5850/9
x=$650
.: the actual price was $650.
20 + 25(times the number of hours) = 282.50
You add the 20 because of the one time service fee.
Now lets work this out.
20 + 25x =282.50
25x = 262.50 (subtract both sides by 2 to get the x's alone)
x = 10.5 (divide both sides by 25 to get just x)
x = 10.5 hours
So the answer is A.
X + 3x = 90 degrees
4x = 90
x = 22.5 degrees
