Find the value of x.
42°
130°
75°

Answer:

Step-by-step explanation:

1) 2/5= 0.4

2) 2 1/8= 2.1

3) 4/33= 0.12

4) -6/11= -0.54

Explanation:

In fractions, the numerator is the number above the line and the denominator is the number below.

The line in a fraction that separates the numerator and the denominator represents division.

To convert a fraction to a decimal, divide the numerator by the denominator.

x + 21 + 3x + 9 = 90

Combine like terms

4x + 30 = 90

Subtract 30 from both sides

4x = 60

Divide both sides by 4

x = 15

Answer:

x = 15

Step-by-step explanation:

You can use the opposite angles property to solve this problem. By using the property, the opposite angle of x+21 must also be x+21. So therefore, you can setup the equation x+21+3x+9=90. Simplify and you should get 4x+30=90. Subtract 30 on both sides and you get 4x=60. Divide 4 on both sides and you get x=15.

Answer:

8x-3

Step-by-step explanation:

The total perimeter is the length of all the sides of the triangle added together, in this case that is 11x+1. In order to get the length of the one side by itself subtract the other two side lengths from the perimeter. (11x+1)-(x+5)=10x-4. (10x-4)-(2x-1)=8x-3.

Answer:

x = - 2

Step-by-step explanation:

Given

- x - 4 + 3x = - 5x - 18 , that is

2x - 4 = - 5x - 18 ( add 5x to both sides )

7x - 4 = - 18 ( add 4 to both sides )

7x = - 14 ( divide both sides by 7 )

x = - 2

Answer:

-563

Step-by-step explanation:

a = -7 , b = 9 , c = 4

9ab +C

9 × -7 × 9 + 4

81 × -7 + 4

-567 + 4

-563

Step-by-step explanation:

20x12= 240cm^2 (the size of one brick)

If there are 5000 bricks then you multiply 240cm^2 by 5000

5000x240= 1,200,000cm^2

(it's a huge number so I'm not so sure about this)

Step-by-step explanation:

(7/8) / (6/9)

= (7/8) / (2/3)

= (7/8) * (3/2)

= (7 * 3) / (8 * 2)

= 21/16.

The result is: 7/8 divided by 6/9 is equal to 21/16.

To divide one fraction by another, we can multiply the first fraction by the reciprocal (inverse) of the second fraction.

The reciprocal of a fraction is obtained by flipping it upside down.

we have to find 7/8 divided by 6/9:

now we find the reciprocal of 6/9.

Reciprocal of 6/9 = 9/6 (Flip the fraction upside down)

Multiply 7/8 by the reciprocal of 6/9.

(7/8) × (9/6)

To simplify the fraction, first, check if both the numerator and denominator share any common factors and then divide both by their greatest common divisor (GCD).

Now, let's calculate:

(7/8) × (9/6)

Multiply the numerators: 7 × 9 = 63

Multiply the denominators: 8 × 6 = 48

The result is 63/48.

Find the greatest common divisor (GCD) of the numerator and denominator, which is 3 in this case (GCD of 63 and 48).

Divide both the numerator and denominator by the GCD (3):

63 ÷ 3 = 21

48 ÷ 3 = 16

The simplified fraction is 21/16.

So, 7/8 divided by 6/9 is equal to 21/16.

Answer: [tex]\overline{VW}=15[/tex] units.

Step-by-step explanation:

Since Point W is on line segment [tex]\overline{VX}[/tex].

That means V,W,X  are collinear such that [tex]\overline{VX} = \overline{WX}+\overline{VW}[/tex]  (i)

Given[tex]\overline{ WX}=2[/tex] units. ,  [tex]\overline{ VX} = 17[/tex] units.

To determine :  length of [tex]\overline{ VW}[/tex].

Substitute all the given values in (i), we get

[tex]17=2+\overline{VW}\\\\\Rightarrow\ \overline{VW} =17-2=15\\\\\Rightarrow\overline{VW}=15[/tex]

Hence, the length of [tex]\overline{VW}=15[/tex] units.

Answer:

The ratio is 2:3

Step-by-step explanation:

There was 750,000 total deaths in the civil war

About 500,000 of these deaths were due to disease and uncleanliness.

To simplify, 50:75 is 10:15 or 2:3.

To solve ratios, just simplify down as much as possible.

Answer:

x=8

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    -1/2*x+3-(-x+7)=0

simplify 1/2

((0 -  (1/2• x)) +  3) -  (7 - x)  = 0

Adding a whole to a fraction

Rewrite the whole as a fraction using  2  as the denominator :

        3     3 • 2

   3 =  —  =  —————

        1       2  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

-x + 3 • 2     6 - x

——————————  =  —————

    2            2  

(6 - x)    

 ——————— -  (7 - x)  = 0

    2      

ubtracting a whole from a fraction

Rewrite the whole as a fraction using  2  as the denominator :

            7 - x     (7 - x) • 2

   7 - x =  —————  =  ———————————

              1            2    

Adding up the two equivalent fractions

(6-x) - ((7-x) • 2)     x - 8

———————————————————  =  —————

         2                2  

x - 8

 —————  = 0

   2  

When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 x-8

 ——— • 2 = 0 • 2

  2

Now, on the left hand side, the  2  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  x-8  = 0

Solve  :    x-8 = 0

Add  8  to both sides of the equation :

                     x = 8

Hope this helps :)

Answer:

x=8

Step-by-step explanation:

Original equation: -1/2x+3 = -x+7

First, you must isolate the x value to be alone on 1 side. Steps 1 and 2 do this.

1. Subtract 1/2x to both sides.

This results in:

-0.5x + 7 = 3

Because -x - (-1/2x) = -x + 1/2x = -0.5x

2. Subtract 7 from both sides.

This results in:

-0.5x = -4

Because 3 - 7 = 4

Then, you simply get rid of the -0.5 by multiplication. Steps 3 and 4 accomplish this.

3. Multiply the whole equation by -1

-1(-0.5x) = -1(-4) —> 0.5x = 4

We did this to make it easier to see the equation.

4. Divide the whole equation by 2

2(0.5x) = 2(4) —> x = 8

Your answer is x = 8 because 0.5 times 2 is 1 and 2 times 4 is 7, and you can now ignore the 1 because anything times 1 is itself.

So x=8.
