4(2x-5)+15=11
8x-20+15=11
8x-5=11
8x=11+5
8x=16
x=16/8
x=2
Hope it helps
Since the angle is in radians, then s = rθ.
Lets simplify each one of the rational expressions using the product rule of exponents:

and the quotient rule of exponents:

We can conclude that you should pair the rational expressions with their simplest form as follows:



Step-by-step explanation:
2x = 18
Divide both sides by 2
x = 9
Answer:
I don't think It's possible to have a division equation for this problem, However here is a multiplication one: 14 * 7 = x
x = 98
Step-by-step explanation:
14 * 7 = x
This works because there are 7 days in a week, and he ran for 14 weeks. 14 times 7 = 98. So x = 98.
