For the first, simply plug in the value of x given (x = 2) into the equation: 
So, 8 would be your answer.
For the second, the sum of x and 2 would be expressed as x + 2. Twice this sum would be written as 2(x+2). Finally, 8 less than twice that sum would be written as 2(x+2) - 8, which would be your expression.
For the last question, the coefficient refers to the number directly in front of the variable, x. So you need only to check what the x would simplify to in each equation and look for the expression where x has no coefficient (i.e., its coefficient is 1). For Hunter, the coefficient would be 15 (5 × 3x = 15x); for Michael, the coefficient would be 11 (6x + 5x = 11x); for Nate, the coefficient would be 1 (x = 1x); and for Spencer, the coefficient would be 2 (2x = 2x). Thus, Nate's expression has a coefficient of 1 when simplified.
Answer:
8.66
Step-by-step explanation:
root 75 is also 5 root 3 (after simplifying)
when that is converted into a decimal we get
8.660254038...
Rounding to the nearest hundred of that number we focus on these two numbers
8.6<u><em>60</em></u>254038...
As a result to the nearest hundreth is 8.66
Answer: I'd assume its B 100 miles each day.
Step-by-step explanation:
Because 70 x 100 is 7,000 which is equal to the amount of miles stared in the question
Answer:
314.16 sq mm
Step-by-step explanation:
formula for area of a circle = pi(r^2)
if the diameter is 20mm then the radius is 10 mm
When you plug in pi(10mm^2) you get 314.16 sq mm
