Divide the miles and time to find the speed.
14.4/3 = 4.8
28.8/6 = 4.8
43.2/9 = 4.8
57.6/12 = 4.8
All the answers are the same, so therefore the speed is 4.8 mph.
Let's start by evaluating the parenthesis on the right. Because of the order of operations (PEMDAS - parenthesis, exponents, multiplication/division, addition/subtraction), we divide 3 by 1/8 first. This is equal to multiplying 3 * 8, or 24. Next, we subtract 5 from 24. This is equal to 19.
Next, we subtract 19 from 3/4. -18 1/4 We complete this problem by adding (1/2)^2, or 1/4. This is: -18 1/4 + 1/4 = -18, so -18 is the answer.
Answer:C
Step-by-step explanation:
MA=80,5-35
MA=45,5
MN/MA=MP/MB
80,5/45,5=96,6/x
80,5x=45,5*96,6
80,5x=4395,3
x=4395,3/80,5
x=54,6m
The answer is =x^2 +x +1 +2/x-1
