Answer:
can i have brainliest? :) hope this helpeddd
Step-by-step explanation:
i don't know what im supposed to match it too but im just gonna solve the equation
2x + 5 = 19
isolate the variable
2x + 5 = 19
-5 -5
2x = 14
__ __
2 2
x= 7
So if you have r^2 + 4s and r=4 and s = 1.5 r^2 is 4^2 which is 16 and 4s is 1.5 x 4 which is 6 so you do 16 + 6 which is 22 so the correct answer is a.
Simple....
What is equivalent to 7(x-3)?
Distributing....
7*x=7x
7*-3=-21
7x-21
Thus, your answer.
Answer:
A
Step-by-step explanation:
One complete turn is 1 perimeter (aka circumference).
We have to find the length it turned, hence, its circumference.
The formula for circumference (C) of a circle is:

Where r is the radius
The radius is HALF of diameter. Given diameter is 250, the radius is:
r = 250/2 = 125 feet
Now, substituting in formula we have:

So, it turned 785.4 feet with 1 rotation.
The correct answer is A
Answer: - x - 120
Explanation: You want to find the opposite of (120-x) not just x, so you just put the negative symbol next to both the variables.
