Give me an expression of nine less than a number

1 answer:

4 0

So if you want it to be 9 less than your number (x) then you would subtract nine.

So it would be:

x - 9.

So if your "number" is 12 then you would substitute x for 12 and it would be 12-9. The answer is 3. So 3 is 9 less than a number (12).

I believe

Solve for X, and show the equation you would use to solve.

kompoz [17]

Answer:

x = 20

Step-by-step explanation:

There are both consecutive interior angles and are supplementary.

The equation should be written like this:

5x + 50 + x + 10 = 180

Step 1: Simplify both sides of the equation.

5x + 50 + x + 10 = 180

(5x+x) + (50+10) = 180 (Combine Like Terms)

6x + 60 = 180

Step 2: Subtract 60 from both sides.

6x + 60 − 60 = 180 − 60

6x = 120

Step 3: Divide both sides by 6.

$\frac{6x}{6} = \frac{120}{6}$

x = 20

Hope it helps!!

Question 1(Multiple Choice Worth 5 points)

Nadusha1986 [10]

Answer: $arc\ length =13.19cm$

Step-by-step explanation:

You need to use the following formula:

$arc\ length=r\theta$

Where "r" is the radius and $\theta$ is is the central angle of the arc in radians.

Assuming that that the angle $\frac{3\pi }{5}$ is the central angle of the arc, and knowing that the radius is 7 centimeters, you can substitute values into the formula.

Therefore, you get:

$arc\ length=r\theta\\\\arc\ length= (7cm)(\frac{3\pi}{5})}\\\\arc\ length =13.19cm$

Students get a 15% discount off the original prices at the Everything Fluorescent store during its back to school sale. Find the

spayn [35]

The discount is $1.19 unless you have to round up than it is $1.20. in order to solve this problem you would set up a proportion. So your proportion would be x over 7.99 = 15 over 100. Than you would cross multiply. 7.99*15=119.85. and 100*x=100x. than u divided both sides by a 100. than x= 1.19. which 1.19 is the discount.
