3 0

Answer:

Infinitely many.

Step-by-step explanation:

Combine like terms as shown below

x + 12 + 2x = 20 + 3x - 8

Side one

x + 2x = 3x

Side two

20 - 8 = 12

Set the equation up again

3x + 12 = 3x + 12

The equation is the same on both sides which means that the equation cancels itself out.

3x - 3x = 0 and 12 - 12 = 0

0 = 0 so there is infinitely many solutions because both sides equal the same thing.

Express secΦ in terms of tanΦ

Sunny_sXe [5.5K]

Answer:

$\sec\theta=\sqrt{1+\tan^2\theta}$

Step-by-step explanation:

The trigonometric identity is :

$\sec^2\theta-\tan^2\theta=1\\\\or\\\\\sec^2\theta=1+\tan^2\theta$

We need to express secθ in terms of tanθ.

The above equation becomes,

$\sec\theta=\sqrt{1+\tan^2\theta}$

Hence, this is the required solution.

a group 5 friends want to buy a flat screen tv for $ 210. the tax comes to $15. write and solve a multiplication equation to fin

Greeley [361]

Let x be the amount each friend pays .

There are five friends contributing ,so 5x will be the total money collected .

It needs to equal the price plus the tax, 210 + 15 = 225

So the equation becomes,

$5x = 210 + 15$

5x = 225

dividing right side by 5, we have

x = 225/5 = 45

Answer: So each frien pays $45.
