Answer:

x = 23 degrees

Step-by-step explanation:

Supplementary angles add up to 180 degrees.  Thus, 3x - 17 degrees plus al 5x + 21 deg must equal 180 degrees.  

Combining like terms, we get 8x - 4 = 180, or 8x = 184.

Dividing both sides by 8 yields   x = 184/8 = 23 = x (measured in degrees)

Answer:

x= -2

Step-by-step explanation:

6x= -12 (subract x on each side then 17 on each side)

x=-2 (divide each side by 6)

Answer:

x + 5

Step-by-step explanation:

This is actually rather simple to figure out. Simply divide 6x + 30 by 6. That should get x + 5 for the length of one side.

The answer is A. 42

Solution:

Let x= ones digit, y=tens digit

1st condition (original number) : 7(x+y)=10y + x

2nd condition (new number by reversing the digits): 18+x+y=10x+y

simplifying:

1st condition: 6x=3y

2nd condition: x=2

substituting x=2 to 6x=3y

y=4

Answer:

1.71

Step-by-step explanation:

x/4 = 3/7

4 * 3 = 12

12/7 = 1.714285714285714

Rounded to the nearest hundreths, the answer is  1.71

2x²y - 4xy²

Substituting the value of x & y,

= 2(- 1)² × 1 - 4(- 1) × 1²

= 2 × 1 × 1 + 4 × 1

= 2 + 4

= 6

Hence, The value of the expression is 6.

60+70+?=180

60+70+50=180

The number of inches in 5 m is 196.85 inches

1 m = 100 cm

Therefore,

5 m = 5 × 100

5 m = 500 cm

2.54 cm = 1 inche

Therefore,

500 cm = 500 / 2.54

500 cm = 196.85 inches

Thus, there are 196.85 inches in 5 m

f(x)=2x-3

Step-by-step explanation:

To write an equation in function notation change the y to an f(x). Then, if you plug something in for x also replace it in f(x). For example, if x=3 then the equation would be f(3)=2(3)-3.

Step-by-step explanation:

Given:

[tex]f(x) = 3^x[/tex]

[tex]g(x) = 3^{2x} - 3^x[/tex]

[tex]h(x) = f(x) - g(x)[/tex]

Then:

[tex]h(x) = 3^x - (3^{2x} - 3^x)\\h(x) = 3^x - 3^{2x} + 3^x\\h(x) = 2 \times 3^x - 3^{2x}[/tex]

The length of the rectangle is x + 9 whose width is gives as 2x.

To find the length of the rectangle, we need to express it in terms of the width.

Given:

width of the rectangle is 2x.

The formula for the area of a rectangle is

A = length × width.

As, the polynomial function for the area:

[tex]A(x) = 2x^2 + 18x[/tex]

So, set up the equation:

[tex]2x^2 + 18x =[/tex] [tex]{\text} width x length[/tex]

Substituting the given width = 2x in above equation gives

[tex]2x^2 + 18x = 2x * length[/tex]

Dividing both sides of the equation by 2x:

x + 9 = length

Therefore, the length of the rectangle is x + 9.
