Answer:
x=841/68
Step-by-step explanation:
-68(x-11)=1+(-94)
-68(x-11)=-93
-68x+748=-93
-68x=-93-748
-68x=-841
68x=841
x=841/68
k = 1.33 or 1 1/3
Formula of Direct variation. Where y is equal to the product of the constant of variation times x.
y = kx
16 = k * 12
k = 16/12
k = 1 4/12 = 1 1/3
Constant of variation is 1 1/3 or 1.33.

Answer: The cost for each subscription is $19.5
Step-by-step explanation:
32m=624
Divide 32 on both sides:
32m/32=624/32
m=19.5
Answer:
Step 1: It should be m∠m + m∠n + m∠o = 180° (sum of angles in a triangle)
Step-by-step explanation:
He made the mistake in Step 1: m∠m + m∠n + m∠p = 180°
It should be m∠m + m∠n + m∠o = 180°
Then only, he can equate it with m∠o + m∠p in step 3.
So, m∠p is the exterior angle and m∠m and m∠n are the two remote interior angles.
m∠o is the adjacent angle to m∠p. They form a linear pair.
Hence, the correct answer is Step 1.
