I do not understand what you are asking but I am going to assume that you are trying to simplify the equation.
First, write the equation.
(4/3)b + 2 = 4 - (1/3)b
Add (1/3)b to each side.
(5/3)b + 2 = 4
Subtract 2 on each side.
(5/3)b = 2
Divide by (5/3) on each side
b = 1.2
b = 1.2 is your final answer.
The answer is 7/1, when you want to know a reciprocal, all you do to the fraction is flip it around. Hope this Helps!
Line Q??? You don't really have an image of it
Answer:
BC ≈ 14 units
Step-by-step explanation:
using Pythagoras' identity in the right triangle.
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
BC² + AB² = AC²
BC² + 18² = 23²
BC² + 324 = 529 ( subtract 324 from both sides )
BC² = 205 ( take square root of both sides )
BC =
= 14.317.. ≈ 14 units ( to the nearest unit )
