Answer: this is the answer please follow to the explanation
Step-by-step explanation:
21x + 14y = 168. X=2y
14y = -21x +168. 2y=x
14 divided by 14 on one side and
-21 + 168 divided by 14 on the other side
You should get...
Y= -3/2x +12
For part 2 where they want you to put the 2 numbers in, you should put the point they intercept which is (6,3).
Well, have a good day
Answer:
2.89
Step-by-step explanation:
Note the equal sign, what you do to one side of the equation, you do to the other. To solve, do the opposite of PEMDAS. Isolate the variable, z.
First, subtract 12 from both sides:
25 = 4.5z + 12
25 (-12) = 4.5z + 12 (-12)
25 - 12 = 4.5z
13 = 4.5z
Isolate the variable, z. Divide 4.5 from both sides:
(13)/4.5 = (4.5z)/4.5
z = 13/4.5
z = ~2.89 (rounded).
2.89 is your answer.

Answer:
The answer to your question is diameter = 19.7 in
Step-by-step explanation:
Data
Circumference = 62 in
diameter = ?
Process
1.- Write the formula of Circumference, remember that circumference = perimeter.
Perimeter = 2πr
2.- Equal the equation to the value given
2πr = 62
-Solve it for r
r = 62/2(3.14)
-Result
r = 62/6.28
r = 9.87 in
3.- Find the diameter
diameter = 2r
diameter = 2(9.87)
diameter = 19.7 in
Answer:
Step-by-step explanation:
Since this is a degree we going to use the arc length formula
where x is the central angle measure and r is the radius.
The radius is 6 and the central angle is 48 so let plug that in the formula
Multiply 2 pi by 6
