Answer:
Radius = 7.995944341
Step-by-step explanation:
You use the circumference formula. C=2πr
Since you have the circumference 50.24 cm. You plug in the circumference.
50.24 = 2πr
You divide by 2 and get 25.12.
25.12 = πr
Then, you divide 25.12 by π.
Your answer is
7.995944341 = r

the answer is “LOSS OF $1.38” :)
If it starts at 5 degrees celsius and raises to 15 degrees celsius in 3 minutes it increases by about 3 1/3 every minute.
times that by 5 and you get 16 2/3. times that by 10 and you get 33 1/3
Answer:
x = -8
Step-by-step explanation:
y = 3x + 14
2x - 3y = -14
So, what is the substitution? Y of course, this is because y is equal to 3x + 14.
2x - 3 (3x + 14) = -14
Multiply 3 with the numbers in the parentheses.
2x - 9x + 42 = -14
So you maybe be wondering why it is a negative 7 instead of subtracting 9 with 2. Using PEMDAS, we always read from left to right. So it is basically 2 -9 and you get -7.
-7x + 42 = -14
Then subtract 42 from both sides.
-7x + 42 - 42 = -14 - 42
Simplify
-7x = -56
Divide 7 by both sides.
-7x / 7 = -56 / 7
x = -8
And you might ask, why we get x instead afterwards. This is because both -7 and 7 cancel each other out leaving us with x.
