12
You want to find an equivalent ratio with 2:3. As the question already gives you 8 where 2 used to be, you need to find out what change occurred to get from 2 to 8 (a multiplication of 4). To find the missing part of the ratio, multiply 4 with 3 to get 12.
Answer:
<h2>
</h2>
Step-by-step explanation:
Rewrite the first equation
Now we have the following system of equations
To solve the system of equations multiply the first equation by -1 and add it to the second equation
+
-----------------------------------
Now substitute the value of x in any of the two equations and solve for y
The solution is:

Answer:
a. d = C/π
b. d = 8/π inches ≈ 2.546 inches
c. r = 61/(2π) inches ≈ 9.708 inches
Step-by-step explanation:
a. The formula for circumference is ...
C = πd
Dividing by π gives ...
d = C/π
__
b. For a circumference of 8 inches, the diameter is ...
d = (8 in)/π = (8/π) in ≈ 2.546 in
__
c. The radius is 1/2 the diameter. So, the radius of a circle is ...
r = d/2 = (C/π)/2 = C/(2π)
For a circumference of 61 inches, the radius is ...
r = (61 in)/(2π) = 61/(2π) in ≈ 9.708 in
Answer:
3x - y = -1
Step-by-step explanation:
Standard form of equation is Ax + By = C
y - y1 = m (x -x1)
y - 7 = 3 (x - 2)
y - 7 = 3x - 6
3x - y = -7 +6
3x - y = -1
