<em>45 = 6n + 3n
45 = 9 n
dividing 9 on other side
45 / 9 = n
5 = n
or
n = 5 answer..</em>
Let the common multiple be x
3x : 2x
3x = 125
x = 125/3
So, B pays 2x = 2 × 125/3 = £250/3
Answer: 2
Step-by-step explanation:
You are not really asked how to find the solutions, just how many there are. The easiest way to solve this is to use a program like Desmos and graph the question. I have done this for you.
Red: line -2x + 1
Blue: quadratic y = -2x^2 + 1
Answer: 2
Divide by 6

Square both sides

Simplify Left side using Trig identities: (Pythagorean, Double Angle)

Solve for x:
5 less than w into an algebraic expression is w-5.
