Answer:
b=
−3
/x
Step-by-step explanation:
Step 1: Add -10 to both sides.
−2bx+10+−10=16+−10
−2bx=6
Step 2: Divide both sides by -2x.
−2bx
−2x
=
6
−2x
b=
−3
/x
Answer:
Step-by-step explanation:

Answer: 288.17
Step-by-step explanation:
y ∝ x
⇒ y = kx
substituting the given value of x and y , the equation becomes
12 = 14 k
therefore
k = 12/14
k = 6/7
The formula then becomes
y = 6/7 x
when y = 247, we have
247 = 6/7 x
6x = 247 x 7
6x = 1729
x = 1729/6
x = 288. 17
