x = 3
Step-by-step explanation:Hi there !
DBC + CBV = 180°
DBC + BDC + DCB = 180° }=> VBC = BDC + DCB
replace
20x + 5 = 9x - 2 + 40
solve the equation
20x - 9x = 40 - 2 - 5
11x = 33
x = 33 : 11
x = 3
Good luck !

Whats x solve 1/3x-2/3=-18
Answer:
[tex]x=-52[/tex]
Step-by-step explanation:
multiple everything by 3 to get rid of the fractions
[tex]3(1/3x-2/3=-18)\\1x-2=-54\\[/tex]
rewrite
[tex]x-2=-54[/tex]
add 2 to both sides
[tex]x-2+2=-54+2\\x=-52[/tex]
Answer:
[tex]x=-52[/tex]
Step-by-step explanation:
[tex]\frac{1}{3} x-\frac{2}{3} =-18[/tex]
Add [tex]\frac{2}{3}[/tex] to both sides of the equation:
[tex]\frac{1}{3} x=-18 +\frac{2}{3}[/tex]
Simplify [tex]-18+\frac{2}{3}[/tex] by multiplying [tex]-18[/tex] in fraction form [tex]-\frac{18}{1}[/tex] to get a common denominator so you can add the two fractions:
[tex]-\frac{18}{1}[/tex] × [tex]\frac{3}{3}=-\frac{54}{3}[/tex]
Now add the two fractions:
[tex]-\frac{54}{3} +\frac{2}{3} =-\frac{52}{3}[/tex]
Now write the simplified equation:
[tex]\frac{1}{3} x=-\frac{52}{3}[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]\frac{1}{3}[/tex]:
[tex]x=-\frac{52}{3}[/tex] ÷ [tex]\frac{1}{3}[/tex]
Use the reciprocal of the dividend ([tex]\frac{1}{3}[/tex]), and multiply by your divisor:
[tex]x=-\frac{52}{3}[/tex] × [tex]\frac{3}{1}[/tex]
[tex]x=-\frac{156}{3}[/tex]
Simplify the fraction by dividing [tex]-156[/tex] into [tex]3[/tex]:
[tex]x=-52[/tex]

The number line below represents which combined inequality? (5 points)
Show your work and write an expression by using these clues:
1. Write a number that is greater than 100, but smaller than 10,000
2. Divide that number by 10, 100 or 1,000
3. The quotient should be a number that is less than 100, but greater than 1
Answer: 10.1
Step-by-step explanation:
Step 1: 1,000 is greater than 100 but smaller then
Step 2: 10,000 1,000 is divided by 10,100 which =10.1
Step 3: and 10.1 is less than 100 greater than 1
Answer:10.1
Step-by-step explanation:
Step 1: 1,000 is greater than 100 but smaller then
Step 2: 10,000 1,000 is divided by 10,100 which =10.1
Step 3: and 10.1 is less than 100 greater than 1

What do the zero exponent and negative exponent properties mean.
Answer:
Negative exponents put the exponentiated term in the denominator of a fraction and zero exponents just make the term equal to one.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Primero, cualquier número elevado a la potencia cero es uno. Segundo, los exponentes negativos indican una disposición. Si un exponente es negativo, necesita moverse de donde está al numerador o denominador. Investigaremos esta propiedad más adelante en el Conjunto de Problemas.
What is the slope of the line shown?
Answer:
The slope is 2, or 2/1
Step-by-step explanation:
If you count the rise/run, you get 4/2, which simplifies to 2/1, which is the same as 2.
The fence is rectangular, so use the formula for the area of a rectangle: .
You know the area (A = 300 ft2) and the width (w = 4 ft), but not the length. The formula would be more useful if it were rewritten to solve for the length in terms of the area and width. Rewrite the formula by dividing both sides by the width.
Use the formula to find the length of fence (in feet) that can be painted.
Answer: New formula is A/w=l
Length equals 75ft.
Step-by-step explanation:
A=l x w Area of a rectangle formula.
A/w=l Solve for length
300=l x 4
300=l x 4
4 4
300/4=l
75=l
The new formula is A/w=l and Length= 75ft.
A=l x w (Area of a rectangle formula)
A/w=l (Solve for length)
300=l x 4
300=l x 4
300/4=l
75=l
What's the vicinity system?
Given a rectangle with duration l and width w, the system for the location is A = lw (rectangle). that is, the place of the rectangle is the duration accelerated by the width. As a unique case, as l = w inside the case of a rectangular, the location of a rectangular with facet duration s is given with the aid of the formulation: A = s2 (rectangular)
The perimeter P of a rectangle is given through the formulation, P=2l+2w, wherein l is the period and w is the width of the rectangle. The location A of a rectangle is given with the aid of the system, A=lw, where l is the length and w is the width.
