Step-by-step explanation:

a-2=3+6a/3

By cross multiply

3(a-2)=3+6a

3a-6=3+6a

to check, 1/2 * 1/2 = 1/4

1/4-1/4 = 0

Tasha lists all the multiple of 3 from 3 to99. Tony lists all the multiples of 5 from 5 to100. What is the first number that is
IrinaVladis [17]

Answer:

  • Multiples of 3 = 3, 9
  • Multiples of 5 = 5, 10

Step-by-step explanation:

In a list of 3 to 99, the first multiple of 3 will be none other than 3 itself because when multiplied by 1, you get three.

The second number will be: 3 * 2 = 6

In a list from 5 to 100, the first multiple will be 5 with 5 being a multiple of itself when multiplied by 1.

Second number = 5 * 2 = 10

Look at the figure and answer
andreyandreev [35.5K]

Answer:

\cos x=\dfrac{8}{f}

Step-by-step explanation:

Given that,

\tan x=\dfrac{e}{8}\\\\\sin x=\dfrac{e}{f}

We need to find the value of cos x.

We know that,

\tan\theta=\dfrac{\sin\theta}{\cos\theta}

Using the above relation,

\dfrac{e}{8}=\dfrac{\dfrac{e}{f}}{\cos x}\\\\\cos x=\dfrac{\dfrac{e}{f}}{\dfrac{e}{8}}\\\\=\dfrac{e}{f}\times \dfrac{8}{e}\\\\=\dfrac{8}{f}

So, the value of cos x is equal to \dfrac{8}{f}.
