Answer:

2x+90°+x°=180

or, 2x+x=180-90

or, 3x= 90

or, x= 90/3

or, x= 30°

Therefore , the value of X is 30°.

Thank you ☺️☺️☺️

Answer:

x=30

Step-by-step explanation:

2x+90+x+90+90=360

Combine like terms

3x+270=360

Subtract 270 from both sides

3x=90

Divide both sides by 3

x=30

23.37

Answer:

-32.27

Step-by-step explanation:

[tex]n^{2}p +p[/tex]

First you have to substitute the values. (n = -1.9 and p = -7).

Substituting it would get to [tex](-1.9)^{2}(-7) + (-7)[/tex].

First you solve the exponent which would get it to [tex](3.61)(-7) + (-7)[/tex].

Then you would multiply to get it to -25.27 - 7.

That gets to -32.27.

Step-by-step explanation:,,

Answer:

The answer is B:subtract 1,add x,divide by 4

The other answer is D:add x,subtract 1,divide 4

Step-by-step explanation:

when you subtract 1 you isolate 3x so the equation looks like 3x=-x+3

the next step is to add x to both sides so you isolate the x to one side after doing that your equation should look like 4x=3,after this you divide both sides to the solution x=[tex]\frac{3}{4}[/tex]

The answer is also D because if you add x to both sides u isolate x to the left side so the equation will look like 1+4x=4 the next step will be to subtract one from each side and after doing this the equation should look like 4x=3 which should look familiar because its the same exact solution as B was so the answer to this choice is x=[tex]\frac{3}{4}[/tex]

With that evidence I can reasonably say that answer to the question is B,and D

Answer: x=3.500

Step-by-step explanation:  product of several terms equals zero.  

When a product of two or more terms equals zero, then at least one of the terms must be zero.  

We shall now solve each term = 0 separately  

In other words, we are going to solve as many equations as there are terms in the product  

Any solution of term = 0 solves product = 0 as well.

   2x-7 = 0  

Add  7  to both sides of the equation :  

                     2x = 7

Divide both sides of the equation by 2:

                    x = 7/2 = 3.500

Formula to convert F to C:

(F -32) x 5/9

F = 63 + 10 = 73

73-32 = 41

41 x 5/9 = 22.77777

Rounded to the nearest degree = 23 C

Answer: 63 +10 =73 then you have to round it right

it would be 70 degrees Celsius

Step-by-step explanation:

it would be rounded to 70 because 73 cant be round to 80 the 3 is ot higher than 5

Answer:

The total cost of the hotel room is $235.20

Step-by-step explanation:

Here, we want to find the total cost of the hotel room

Total cost of hotel room = Cost of hotel room for the two nights + tax

Tax = 12%

Total cost = 210 + 12% of 210

Total cost = 210 + (12/100 * 210)

Total cost = 210 + 25.2

Total cost = $235.2

Answer:

m = -2

Step-by-step explanation:

m - 5 - 6m = 5

First, you need to combine like terms

-6m + m = -5m

-5m - 5 = 5

Next, add 5 to both sides of the equation

-5m - 5 = 5

    + 5   + 5

-5m = 10

Divide -5 by both sides of the equation

-5m = 10

÷-5    ÷-5

m = -2

Answer:

12.3 + 9.6 = 21.9

Step-by-step explanation:

The number 21.9 means that when she rode the Ferris wheel from the bottom to the top, Vivian's height rose by 21.9 feet.

The slope of a line would be -6 which is perpendicular to the line whose equation is 2x+12y=−192.

The slope of a line is defined as the angle of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

We have to determine the slope of a line perpendicular to the line whose equation 2x + 12y = −192.

First, we have to find the slope of the given line

The equation of the line which is given as

2x + 12y = −192

12y = −192 - 2x

Divided by 12 both sides of the above equation to get the slope-intercept form

y = - (1/6)x - 16

Here the slope of the line (m) = -1/6

So the slope of the line perpendicular to the line will be: 1/m = 1/(-1/6) = - 6.

Answer:

x= -10

Step-by-step explanation:

distribute 7 to x and 3: 7x + 21 = -49

subtract 21 from both sides to isolate the variable: 7x= -70

divide both sides by 7 to find x: x= -10

Answer:

X = -10

Step-by-step explanation:

1.- 7x + 21 = -49

Subtract 21 on both sides of the equal sign

You should have:

2.- 7x = -70

Divide 7 on both sides of the equal sign

You should get the answer:

X = -10

Answer: x = 3

Step-by-step explanation: Simplify both sides

2x - 9x + 17 = -4

2x + - 9x + 17 = -4

Combine like terms

(2x + -9x) (17) = -4

-7x + 17 = -4

Subtract 17 from both sides

-7x + 17 - 17 = -4 - 17

-7x = -21

Divide both sides by -7

-7x/-7 = -21/-7
