Answer:
x=4
Step-by-step explanation:
5(x-10) = 30- 15x
5x - 50= 30 - 15x
+15x +15x
20x - 50 = 30
+50 +50
20x = 80
/20 /20
x = 4

Answer:
42580 miles
Step-by-step explanation:
Mean = 
The manufacturer does not want to replace more than 5% of the tires
By using normal table values :
Hence the approximate number of miles for the warranty is 42580 miles
35x – 13 x = x – 1
⇒ 22 x = x - 1
⇒ 22x - x = -1
⇒ 21x = -1
⇒ x = -1/21
Thus,the value of x is -1/21
Answer:
x=21.
Step-by-step explanation:
First you distribute 3 to the parenthesis. You should get 3x-21=42 at this point. Then you add 21 to 42 to get 63. Here you should be at 3x=63. Divide 63 by 3 to get x=3
Answer:
2x^2+16x-66
Step-by-step explanation:
Use FOIL (First, Outside, Inside, Last)
(2x-6)(x+11)
F- 2x*x=2x^2
O-2x*11=22x
I--6*x=-6x
L--6*11=-66
2x^2+22x-6x-66
Combine like terms
2x^2+16x-66
