Given that 110ₓ = 40₅ , find the value of x.

x = 4

Step-by-step explanation:

110ₓ = 40₅    --------- change all to base ten.

the system called binary

1x²+1x ¹+0x⁰ = 45¹+0*5⁰

x² + x + 0 = 20

x² + x – 20 = 0

solve x using Quadratic equation

       -1 ±  

x =  ------------------------------------

                       2 * 1

x = -5;  x = 4

therefore, x = 4

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32

step-by-step explanation:

a child is 12 years old, and his father is 32 years older. in how many years will the age of the father be 2 times the age of the child?

this needs to be the answer format, or else your answer is incomplete.

if the number of years is x, then the equation is

in __ years
