What is the value of x?

Mathematics
1 answer:
Firlakuza [10]3 years ago
8 0

(10 + 3x)° + (x - 30)° = 180°

(3x + x)° + (10 - 30)° = 180°

4x° - 20° = 180°

4x° = 180° + 20°

4x° = 200°

x° = 200/4

x° = <u>50°</u>

So, the value of x is 50°

Does the equation 6x + 35 = -6x - 35 have no, one, or infinite solutions?
fenix001 [56]

Answer:

The equation has one solution.

Step-by-step explanation:

6x + 35 = -6x - 35

subtract 6x from both sides of the equation

35 = -35 - 12x

add 35 to both sides of the equation

70 = -12x

divide -12x on both sides of the equation

x = 5.833333333

6. (08.02 MC)
MariettaO [177]

Answer:

The percentage change in volume between cylinder A and cylinder B is 50%

Step-by-step explanation:

The volume of a cylinder is given by the formula

V= πr^2h

For cylinder A, where r=7 and h= 5, π=22/7

V= π * 7^2 * 5

V= π * 49 * 5

V= 769.69 cubic inch

For cylinder B

V= 490π

V= 1539.3804 cubic inch

The percentage change in volume between cylinder A and cylinder B

=[ (VA- VB)/VB] *100

=( 1539.3804 - 769.69) / 1539.3804

= 0.5000 * 100

= 50%

If the triangles are congruent, then X=?
steposvetlana [31]

Answer:

Hi there!

The correct answer to this question is: x=3

Step-by-step explanation:

because these two triangles are similar, that means the hypotenuse are similar. which means you can set the sides equal to each other like this:

13 = 4x + 1   minus one on both sides and you should get 4x = 12 and then divide 4 on both sides and you should finally get x = 3

Find the value of the expression. 7! ÷ 3! 5,040 5,034 840 24
koban [17]
First, let's review what the "factorial operator"  !   means.

5! = 5*4*3*2*1.

3! = 3*2*1

7! = 7*6*5*4*3*2*1

Then:  

 7!         7*6*5*4*3*2*1       7*6*5*4         5040
----- = ----------------------- = ------------- = ----------- = 5040 (answer) 
 3!              3*2*1                     1                  1
