Answer:
x=-3
Step-by-step explanation:
- -2 (-5+8x)+6=40-8x
- 10-16x+6=40-8x
- 16-16x=40-8x
- -16x+8x=40-16
- -8x=24
- x=-3
A. 6.19% that is the correct answer
Answer:
15 Doughnuts
Step-by-step explanation:
First, subtract 1.30 from 20.05
You get: 18.75
Now divide 18.75 by 1.25 to find the number of doughnuts he bought.
Therefore, he bought 15 doughnuts
The answer is 6x
Because x is equal to 1x so 1x+2x+3x = 6x
Hope this helps :)
You can solve this problem and calculate the arc lenght, by applying the following formula:
s=θr
s: it is the arc lenght.
θ: it is the central angle (θ=2π/3).
r: it is the radius of the circle (r=10 inches).
When you substitute these values into the formula, you obtain the arc lenght (s):
s=θr
s=(2π/3)(10)
Then, you have that the value of the arc lenght is:
s=20.94 inches
